Re: Types of Chisel

Correct angle for a wood chisel, standard bench and butt chisels are traditionally ground at the factory to 25°, and this is fine for most work, but the edge will last longer if you add a 5° microbevel to make a 30° cutting angle.

Grind the chisel until its blunt end is sharp. Dip the chisel in water every five seconds or so to prevent the metal from overheating. Use a protractor to draw a 25-degree angle on a piece of cardboard, then cut the cardboard with a pair of scissors. Adjust the grinder's tool rest to this angle.

An important aspect of using a hammer is listening. So, for instance, when you are using a chisel hammer to assemble a joint, listen carefully to ensure that the joint is going together. Continuing to hammer something that is being prevented from moving (because it is too tight or misaligned) is counterproductive and may well result in damage. Some hammers, such as the chisel hammer and the cross-peen hammer have two hammering options, it is important to use these for the right jobs, if they are misused they can become damaged. For example the chisel hammer has a rubber face which is great for using directly on wood, however if you were to use it to drive a nail you would damage the rubber face. The cross-peen hammer has a slightly domed face and a tapered end, the tapered end is great to drive the first strike into small nails, it gives you a precise aim when holding the nail between your thumb and forefinger.

In stone working, chisels are used to carve or cut stone, bricks or concrete slabs. Different types of stone chisels are used, depending on the specific function being performed. Stone chisels are normally hit with club hammers to increase the force and therefore cut the stone.
