Power tools can be classified in the following basic types according to their application range:
In addition to this, there are power tools for special applications and combination types.
Power tools work according to the following basic principles:
The basic principles are used individually or in combinations.
Volt is the unit of measure of electrical voltage.
Watt is the unit of measure for (electrical) power.
You have to know the characteristics of the material you are working on.
No. You have to go by the material characteristics.
The softer the material, the higher the speed. The harder the material, the lower the speed.
As there are very different hardness ratings within materials, you should always drill with the right speed that is adapted to the material and the drill bit diameter.
In technical literature there are application tables that have been calculated in detail. The speeds listed here in our table must be seen as simplified guidelines that can be used to achieve good results with hand-held machines.Other speeds may apply for special drill bits and core cutters. It is best to consult the values specified on the packaging or in the user manual.If you cannot precisely define the speed of the drill used, then use the nearest value.
The user of drills is primarily at risk of possible back torques. Back torques occur when the drill’s torque output increases due to increasing friction of the bit in the hole when
Extremely high, dangerous kick-back can occur if the power tool jams.
The possible kick-backs during drilling can be avoided as follows: Always use immaculate, sharp drill bits. Damaged or blunt drill bits have considerably higher friction and can very easily get jammed or stuck.
Encourage the chip flow when drilling deep holes by regularly retracting the drill bit. This reduces drill bit friction and with it the risk of jamming.
When drilling large diameter holes, select the suitable speed and fix the workpiece.
Generally pre-drill when drilling holes of over 6 mm diameter in metal. This measure will mean that less feed pressure is required. This is especially advantageous when drilling thin sheet metals because it enables you to adjust the feed pressure more precisely when removing the drill bit from the workpiece, which prevents the cutting edge of the drill bit from getting caught. As a rule of thumb, for pre-drilling you choose a drill bit with a diameter that matches the chisel edge width of the large drill bit.
Back torques are absorbed by handling the machine safely. It is therefore necessary to hold and guide the drill with both hands. Drills that are intended to be used with an auxiliary handle must be used with the auxiliary handle.
The spindle on the drill is securely fixed in the bearings. This provides a high level of true running precision. The speeds are optimised for drilling in metal. The spindle on the impact drill is positioned in the bearings as a moving part. The true running precision is not as good as on normal drills because of the different system. The speed is usually higher than that of drills because stone is also drilled, which requires a high impact rate.
Tool reactions can occur when tightening and loosening screws, which can endanger the user. The causes are
Impermissible and therefore dangerous back torques can be avoided by the following measures:
The most common cause of bit slipping is:
It is not difficult to see that an application error is to blame in each of these cases.
The effects of bit slipping are:
You can see that it is worth avoiding these common application errors.
Nearly all screwdriving applications can be classified as one of two basic types: hard screwdriving applications and soft screwdriving applications.
There are machine screws and wood screws. There are different versions of these basic types for various building materials and special applications. They differ in terms of their shape and their type of thread.
In principle, the different types are:
Sanding or grinding surfaces is called surface sanding or surface grinding, whereas cutting materials by grinding them is called cut-off grinding or deep grinding.
Nearly all solid materials can be sanded or ground. Only certain material types such as elastomers can either not be sanded or ground at all or only with extreme technical measures.
The application range is based on the abrasive used and is universal. Orbital sanders are preferably used for working on wood, wood-based materials and painted surfaces. They are less suitable for metals and stone materials because the material removal rate is very low.
Orbital sanders are excellent for flat surfaces. There is a risk of sanding through here and there on sharp corners and edges and on convex or concave curved surfaces due to the hard, flat sanding plate. This can also damage the sanding plate.
The application range is based on the abrasive used and is universal. Angle grinders are preferably used for grinding metal and stone. The grinding position becomes very hot due to the tool’s high circumferential speeds. Angle grinders are therefore less suitable for wood-based materials and plastics.
Virtually all workpiece shapes can be worked on. Angle grinders are, however, less suitable for workpieces that need to be given an absolutely flat surface because the high material removal rate means that application errors will inadvertently cause deep grinding marks.
The main risk of injury on sawing power tools is posed by the saw blade – both when the tool is at standstill and when it is working. There is also the risk of machine kick-back resulting from application errors. You must only use sharp saw blades in immaculate condition. The saw blades must be suitable and permitted for the corresponding saw. Blunt or damaged saw blades can lead to jamming and machine stalling. Injuries caused by the saw blade can be avoided by the following measures:
Set and fix adjustable safety mechanisms such as the riving knife according to instructions.
The saw must be guided securely and firmly during work. When doing so, choose a feed pressure that does not cause the saw to jam or stall. This could cause kick-back torques to occur.
With the exception of certain mineral materials and glass, virtually all materials can be cut with hand-held electric saws.
Hand-held circular saws are basically suitable for all sawable materials by using the corresponding saw blade.
The main application range of the circular saw is fast and precise trimming and sizing of panel-shaped components by means of straight cuts. Cutting depths of up to 100 mm or more are used the carpentry trade, but handling such large hand-held circular saws is risky due to the high back torques that occur when the saw blade jams.
Metals cannot be sawn with the tandem saw because of the way it works:
the metal chips that get between the saw blades and in the bar guide would weld the saw blades stuck as a result of friction. Plastics can be sawn to a limited extent: the chips and dust from foamed thermoplastics, especially styrene based (e.g. polystyrene), heat up between the saw blades and the guide as a result of friction. After cooling down, they jam the saw blades because of the hot glue effect. With carbide tooth tipped saw blades, however, they are also suitable for sawing soft and porous stone materials such as aerated concrete and soft lightweight bricks. The saw blades can be changed without the need for additional tools.
The tandem saw is primarily intended for working on wood in the carpentry trade. Beams are usually cut to length and tenon joints are produced. The tandem saw is used just as often in structural work to cut aerated concrete components.
Hand-held chainsaws are used only for working on wood. They are used to quickly cut and trim beams and square timbers and fresh (“green”) wood in the gardening and forestry trade.
Sabre saws are basically suitable for all sawable materials by using the corresponding saw blade.
The sabre saw is typically used in installation and plumbing, vehicle construction, metalworking and pallet recycling.
You must read the user manual because battery technology changes quickly, which may require a new method of operation.
Self-discharge refers to the process by which a battery passively emits energy through storage alone. Once a certain time has elapsed, the battery must be charged before it can operate a garden tool. The self-discharge with conventional nickel technology is approximately 25% per month, whereas with Li-ion it is less than 2%. Li-ion batteries are therefore ready to use even after prolonged periods of storage.
Memory effect occurs in NiCd batteries if they are not fully discharged. If a part of the battery is not used, the battery “remembers” this. The unused part of the battery is then no longer available for storing energy in the battery. This memory effect cannot occur in Li-ion batteries.
Li-ion batteries should be stored at room temperature. Storage at higher temperatures reduces the lifetime of the battery. Li-ion batteries can be destroyed by temperatures above 55 °C, and can suffer deep discharge at temperatures below –15 °C. Li-ion batteries should not be fully charged prior to long-term storage. The activity in a fully charged cell is higher than a partially charged cell, which causes the cell to age more quickly.
Brand-name batteries, particularly those in Bosch garden tools, are protected by a variety of safety mechanisms. An explosion is virtually impossible. Nonetheless, short circuits or mechanical damage to the pack should be avoided at all costs.
You give them back to the power tools dealer. He collects them and passes them on to the power tools manufacturer who then arranges for them to be recycled properly.
The main risk of injury on routers is posed by the sharp router bit – both when the tool is at standstill and when it is working. Routers work at very high rotational speeds. Improper operation can lead to machine kick-back. You must only use sharp router bits in immaculate condition. The router bits must be suitable and permitted for the corresponding router. Blunt or damaged router bits can lead to severe vibration, machine kick-back and bit breakage. Injuries caused by the router bit can be avoided by the following measures:
When routing edges, the feed direction must always be opposite to the bit’s direction of rotation (upcut routing). When routing in the bit’s direction of rotation (downcut routing), the machine cannot be guided safely, especially at higher cutting depths. The severe evasive movements of the machine can cause the user to lose control over the router, which poses extreme risk of an accident. The router must always be guided securely and firmly.
The selected feed pressure must not cause the machine to lose speed too much, which causes vibration.
Hand-held power tools for routing are known under the generic terms routers or plunge routers. The term “plunge router” describes the fact that the router bit is first located above the workpiece and has to be lowered to start routing.
Hand-held routers differ in their application purpose and power consumption. The common types are:
In general, all free-machining materials, especially wood-based materials, can be processed. Metals can only be processed with heavy, stationary routing machines. Only thin aluminium sheets can be processed with hand-held routers.
The hardness of wood is relatively low which makes machining easy. However, if local temperatures get too high, for example, if you stay in one spot for too long, it tends to burn.
The elasticity especially of long-fibred soft wood exerts a certain clamping force on the router bit which is converted to additional frictional heat. In case of solid wood it is very important to respect the grain direction if you want to achieve good results.
The source of danger on an electric planer is the high-speed rotating cutter shaft (“planer shaft”). As a result of momentum, the planer shaft continues to run for some time after the planer has been switched off. Until complete standstill is reached, the planer shaft must therefore not come into contact with the user or other objects, e.g. the work bench.
To prevent danger, you should not put the planer down until the planer shaft has come to a standstill. It is easiest to use a planer type that has a parking feature (“parking rest”). This feature prevents the planer shaft from touching the surface underneath. You must nevertheless ensure that there are no objects on the surface.
All free-machining materials can be planed. However, portable electric planers are almost exclusively used to process wood and wood-based materials. The processing of plastics is possible if the planing width is low (approximately 20-50 mm, depending on the type of plastic).
In comparison to other materials, wood is relatively soft and can therefore be perfectly processed by material-removing techniques. As a “naturally grown” processed material, it has a fibrous structure in natural state and, due to differing growth conditions, it is marked by irregularities, for example, branches. This has to be taken into account during machining since it has an influence on the surface quality.
When the planer is brought into starting position the operator pressure must be applied to the front of the planer base, otherwise the result will be a dent in the surface.
When the planer is taken off the planed material the operator pressure must be applied to the rear of the planer base, otherwise the result will be a dent in the surface.
The correct planing direction has to be chosen to make sure that the planer does not cut against the emerging fibres since this would deteriorate the surface quality. By setting the planer on at a slight angle to the feed direction one can produce an “oblique drawing cut” which improves the surface quality (planer blade does not penetrate into the workpiece across the feed direction but diagonally to the feed direction).
As a rule, only wood and wood-based materials can be stapled and only if the wood is not too hard. Natural wood and plywood can be more easily stapled since the fibres exert an additional clamping force. Other wood-based materials like chipboard can only be reasonably successfully stapled if resin-coated staples are used.
All hard materials, for example, metals, stone-based materials, glass and hard plastics can not be stapled.
Tackers are exceptionally safe if used as instructed. They should always be applied directly on the workpiece and never to “shoot” staples through the air. Many tackers are therefore equipped with a mechanical safety device which prevents their actuation unless they are pressed against hard materials.
Glue guns are electrically safe, however, they should not remain unsupervised in switched-on condition like all electric appliances. The high melting temperature of 150...180 °C of the adhesive, however, requires your attention during application to avoid skin burns.
All materials with absorbent or porous surfaces and with suitable resistance to heat can be glued with the hot glue gun. Typical materials are wood, wood-based materials, stone-based materials and fibre-based materials such as fabrics, leather, cardboard and paper.
Materials that cannot be glued are those with a smooth, non-absorbent surface such as glass, metal and smooth plastics, as well as heat-sensitive plastics such as polystyrene foams. If in doubt, perform a gluing test.
If you follow this procedure and paint away from the window, i.e. with the incidence of light, all colour transitions will disappear and you will prevent unattractive shading.
The choice of paint type depends on the application range: Do you want to paint your furniture? Are you painting your walls? Do you want to protect your patio against weather effects with a varnish?
Suitable for painting ceilings and walls (indoors). They have good adhesive properties, even out surface irregularities on boards, plasterboard or cement fibres, seal pores on plastered walls and concrete, and are preferred for painting ingrain and anaglypta wallpapers.
Special emulsion paints which are usually permeable to water vapour, but very hard-wearing, scruff-resistant and insensitive to standard detergents. They are mainly used in damp rooms such as bathrooms or laundry rooms and in heavy duty rooms such as garages or kitchens.
Colour paints or other paints with especially finely distributed, low pigmentation. They are used when you want the texture of the substrate to remain visible. Wood is protected by varnishes against weather effects, UV radiation, and in some cases against fungi and insects. Wood surfaces can be given a consistent colour by the varnishes, which can also be used on concrete to balance out any colour variations.
Lacquers are mostly opaque coatings. Once it has dried, the coating gives a high-quality, good-looking matte or shiny surface. They are resistant to chemicals and are mainly used to coat wood, metal, plastic or mineral material.
In principle, colourless paint should not be used on windows, wooden panelling or any other wooden components that are situated outdoors.
Colourless paints and light varnishes do not provide sufficient UV protection. UV radiation will cause the wooden surface to lose its ability to hold paint, the wood will turn from brown to grey, the paint will crack and peel away from the wood.
White, covering coatings usually provide the most durability. Sufficiently pigmented varnishes have proven effective on panelling or fences.
A levelling instrument is a tool for measuring the relative height of objects.
By projecting laser lines onto the wall, a laser levelling instrument makes it easier to perform tasks such as precisely hanging up pictures, shelves or wall cupboards and precisely aligning objects in relation to each other.
The path between the measuring instrument and the measuring object must be free of obstacles. You therefore have to measure past obstacles.
Measuring errors can also occur if smoke or dust absorb or partially reflect the measuring beam.
The lasers used in Bosch measuring tools correspond to laser class 2, which is classed as safe. There is therefore no need for any particular safety measures. In general, however, laser beams should never be aimed directly into the eyes, regardless of their protection class.

2) The required part belongs to an assembly. In this case, it is only possible to order the whole assembly.
3) The required part is not in stock or no longer available. To find out more detailed information about delivery times, please contact our service hotline.
Spare parts are integral components of a power tool. They are part of its standard equipment – without them it is not possible to operate the tool. Examples of spare parts are toothed belts, bolts, brackets and carbon brush sets.
Accessories are function-enhancing attachments or additions, without which a power tool can still be operated normally. Examples of accessories are saw blades, carrying cases, auxiliary handles, sanding paper and drill bits.
Collection of tools during the warranty period is free of charge. For repairs after the warranty period has expired, there are one-off shipping costs of 7.14 euros (incl. VAT).
The current prices can be found in our calibration service brochure.
If you discover external damage to the parcel when the spare part shipment is delivered, then refuse acceptance or show the damage to the postman/delivery agent.
If, whilst unpacking the goods, you discover material defects or you have ordered the wrong spare part, then please inform us as soon as possible (within 15 days at the latest). Please also check our delivery conditions on this point.
Before you return the goods, you must request a returns note from us, quoting the delivery note number.
Yes, disposal is free of charge. Batteries and rechargeable batteries can be recycled in all GRS containers (Common Collection System). Old tools can be handed in at your specialist retailer.
Your faulty tool can be sent directly to our service centre. Another option is to hand it in at your local retailer or DIY store.
When sending it to us directly, it is important to ensure that the repair order form is filled in and enclosed with the faulty tool, thus enabling your order to be processed quickly.
If you send the form to us by 5 pm on a working day, the tool can be collected the next day. You can, of course, choose a different collection time.
Bosch tools and their batteries are both registered. The WEEE number (Waste Electrical and Electronic Equipment) is: DE-86520394.
The registration number for batteries and rechargeable batteries is 21001568.
At Bosch Power Tools, we have recourse to a comprehensive logistics network and optimally organised service processes.
The same rules for a repair apply to the calibration service, which means that the user can normally expect to have the tool back after five days at the latest.
Basically, your tool should be packed in such a way that it cannot be damaged during shipping. If you do not have suitable packaging for large tools, please feel free to call us. We will send you an appropriate cardboard box.
For further information on packaging, please read the general terms and conditions of our transport services provider GLS.
No, but this is how we proceed:
In the case of a warranty claim, the repair is, of course, free of charge.
Once the warranty has expired, the following applies:
If the repair costs are less than 50% of the new price, we repair the tool immediately. The repair costs are listed clearly in the invoice.
If the repair costs are more than 50% of the new price, you will receive a cost estimate.
Furthermore, you have the option of an “advance release”:
You decide beforehand if the tool with a repair price above 50% should be released for recycling or if you would like a cost estimate.
In case of an advance release, you are exempt from the shipping costs.
The Bosch calibration service is open to any brand. Upon agreement, we can calibrate not only our own brand of tools, i.e. “Bosch” and “CST/berger”, but also all other brands.
You can decide if the tool remains at the service centre and is recycled there, or if you would like to have it back. In this case, there is a handling charge of 17.85 euros, plus shipping costs of 7.14 euros (incl. VAT).
In the case of a warranty claim, there are, of course, no shipping costs.
For repairs after the warranty has expired, there is a one-off cost per order of 7.14 euros (incl. VAT).
The guarantee on new products is 24 months for private use. Please refer to the current guarantee conditions for detailed information.
You normally receive the repaired tool back after three to five working days at the latest.
Ampere is the unit of measure of electrical current.
That depends on the intended use. DIYers prefer the impact drill because of its versatility, whereas professionals prefer the drill for its precision.
This term denotes the screwdriving accessory required for the particular screw type (slotted, cross head, hex, Torx, etc.). The bit is fixed in the machine either directly via a hex shank in a chuck or in a bit holder that is either part of the machine or an inserted accessory.
The application range is based on the abrasive used and is universal. Random orbit sanders are preferably used for working on wood, wood-based materials and painted surfaces. When used with the right accessory, random orbit sanders are excellent for polishing work. The work rate is lower when sanding metal or stone materials.
Virtually all workpiece shapes can be worked on due to the round sanding plate, which is available in various hardness ratings. Working on sharp corners and edges can lead to sanding through and to damage on the sanding pad.
You always begin with a coarse grit and then choose a finer grit for each stage. As a rule of thumb, you choose a grit that is twice as fine for each subsequent stage.
For example: grit sequence 40 – 80 – 180 – 360 – 600 – 1200
Jigsaws are basically suitable for all sawable materials by using the corresponding saw blade.
Jigsaws are particularly suitable for complex work with curved cuts in all materials. Of all saws, they have the largest selection of universal and special saw blades.
Lithium-ion batteries are based on a new technology that uses lithium as a component in the electrodes. They differ fundamentally from nickel-based batteries and have a cell voltage of 3.6 volts, which is three times as high as nickel cadmium batteries. Less battery cells are required, which enables the power tool to be smaller and lighter or more powerful at the same size. Unlike nickel cadmium batteries, lithium-ion batteries do not have memory effect. They also have considerably less self-discharge.
