“Mains voltage” is the term used to describe the electrical voltage provided in the electricity network by a power supply company. It is 230 volts in Europe and in most countries in the world.
Scribing implement on the end of a marking pin. To drill congruent holes in two workpieces for a wooden dowel joint, you first drill the holes in one of the workpieces. You put marking pins through the drilled holes, and the tips of the pins scribe the exact position where the holes should be on the other workpiece.
The material removal rate provides a meaningful reference value for comparing different power tools, such as planers or sanders. Put simply, it states how much material (stock) is removed in a certain time (usually measured by the hour) from the workpiece. As a rule, the higher the material removal rate, the more effective the tool.
What is known as “memory effect” can occur in nickel cadmium batteries. These batteries have a “memory”, so to speak, and should be completely discharged before they are recharged. If this is ignored too often, the battery seems to “remember” the energy requirement. Over time, the charge capacity diminishes, which causes the battery to become flat faster when it is used. This effect does not occur in lithium-ion batteries.
There are different metal types for different applications. Some of the technically most important metals are aluminium, lead, chrome, iron, cadmium, cobalt, copper, magnesium, manganese, molybdenum, nickel, platinum, plutonium, quicksilver, titanium, uranium, tungsten, zinc, tin.
Metals are divided into light and heavy metals and have properties such as good electrical conductivity and high heat conductivity. When metals are worked on, they can develop a high surface gloss. There are many metal types that are suitable for different applications.
To join two workpieces at an angle, the surfaces to be joined are cut at an angle (usually 45 degrees). These mitre cuts can be produced using circular saws with a guide rail or with bench-mounted saws (e.g. sliding mitre saws). Some DIY stores rent out bench-mounted saws – but an expert DIYer can also use a hand-held circular saw with a guide rail to produce a mitre cut.
Feature for protecting an electric motor against overload. If the performance limit of a power tool is reached during operation, the motor protection switches the tool off before the motor is damaged.
