      A sander is a hand-held power tool, mainly for working on surfaces. There are all different kinds of sanders depending on the application. Wooden or metallic surfaces, for example, can be worked on with a sander if the correct sanding paper is used.

      There are various hand-guided sanding tools depending on the application. Here are the most common ones:

      Belt sander– For sanding with a high material removal rate.

      Delta sander– The specialist for corners, edges and profiles.

      Random orbit sander– For fine sanding and polishing on straight or curved surfaces made of various materials such as wood, metal, plastic, roughcast and paint.

      Multi-sander– Combination of orbital sander and delta sander.

      Orbital sander– For sanding large surfaces.

      Sanding paper

      Sanding paper (also called sandpaper or emery paper) is an accessory for surface finishing and is used together with a sanding tool or by hand. There are various sanding paper types, which are labelled by different coatings for wood, paint or metal. Sanding paper is categorised according to what are known as grits, which are specified in numbers and indicate the material removal rate. The lower the grit number, the rougher the sanding paper and the higher the material removal rate.

      Screw types

      There are many different types of screws for different purposes. They differ in terms of thread type, thread pitch, thread form, screw head shape and screw drive. The most common screws are:

      Machine screws– For driving screws in metal parts.

      Tapping screws– For joining metal plates up to twelve millimetres.

      Self-drilling screws– For joining steel, aluminium and other non-ferrous metal plates.

      Drywall screws– For joining plastics, wood, plasterboard and aluminium.

      Wood screws– For driving screws in wood parts.

      Chipboard screws– For fixing chipboard.

  • Screwdriver bit

      Screwdriver bit

      The screwdriver bit is a replaceable screwdriving insert. Depending on the application, the shank of the bits can be clamped in a bit holder, a ratchet or a torque spanner. However, the bits are mostly fixed either directly or by means of a bit holder in the drill chuck of the tool. Since the bits have to fit the respective screw head exactly, there are also corresponding screwdriver bit types to suit the various screw types.

  • Screwdriver bit types
    • Screwdriver bits are available in many shapes and sizes: slotted, Phillips (cross head), Pozidriv, Torx, Allen, etc., so that the bits fit the screw heads exactly and guarantee perfect guidance when screwdriving.

  • Scribing square
    • Measuring tool that helps to “scribe” shapes and dimensions on a workpiece, i.e. to mark them with a pencil or scriber. A scribing square usually consists of two arms that are joined at a right angle. However, there are also special models, for example, for staircase building (with several adjustable arms) or for window and door building (with the most common rebating and grooving depths).

  • Set screw
    • Everyday term for grub screws that do not have a widened head. The profile for the bit holder (screwdriver, Allen key) is integrated into the screw cylinder. The “headless” outer form, which is reminiscent of a grub, gives the grub screws their nickname.

  • Shaft collar
    • Ring made of cast iron or wrought iron that precisely fits on a shaft and can be fixed on the shaft with one or more screws. The shaft collar holds the shaft itself or moving parts on the shaft in a certain position.

  • Simplex clamp
    • Connector for cords and wire or steel cables. The cables or cable ends are fed through narrow gaps in an oval metal clamp. Then a counterpiece is screwed onto the clamp. It squeezes the wires apart, thereby force-fitting them in the narrow gap. Often used in lamp constructions with metal tension cables.

  • Skirting board
    • Wall trim of a floor covering. It is used to cover the joint between the floor covering and the wall. In doing so, it protects the bottom area of the wall and serves as a design element.

  • Space ring (sleeve, pipe, tube)
    • Small building component that is used either as a spacer between two components (e.g. to leave a gap for rear ventilation on wooden parts) or as a lining to enlarge a round component so that it fits in a clamp or a similar mount.

  • Speed control
    • Control device that adjusts the speed of a motor to a certain, preselected value. This makes it possible to operate tools at a constant speed despite varying load. It is used, for example, in impact drills to adapt the rotary speed of the drill bit to suit the material that is being drilled into.

  • Straight bit
    • Accessory for a router. The straight bit is used to make rectangular grooves and holes in wood, plastic or panels. The straight bit is mounted in the router, and the router is guided to the workpiece from above (in contrast to a bench-mounted router, which routs from below).
