Types Of Chisels
by Rick Oconor
Types of chisels; Most chisels today have plastic handles which can be struck with a hammer or with a mallet without danger of splitting. In fact, some carpentry chisels for use on wood are made of one-piece steel. Size is a factor in selection. The shortest is the butt chisel, about 7 to 9 inches long, for use in tight spaces. Next is the 9-to-10 1/2 inch pocket chisel, preferred for general shop work. Largest is the mill chisel, 16 inches long, good for heavy work but seldom used in the home shop. Intended purpose is the other basic carpentry consideration. The paring chisel is thin-bladed, new-ground to a 25- degree edge, often re-ground to 15 degrees. Drive it by hand only for precise shave cuts in fitting work. The firmer chisel has a thick blade for heavy driving. The gouge is a hollow-blade type. Firmer gouges may be bevel-ground inside or outside, paring gouges are bevel-ground inside only.
Work only with sharp chisels, and use them only for material removal that other carpentry tools cannot do. In lap-joint work, make close parallel saw cuts across the joint area, not quite to joint depth, and remove the material between the saw cuts. Then pare down to joint level with a chisel. In cutting a mortise, first score the outline with a knife so any surface splitting won't extend beyond it. Then bore out the bulk of the wood within the outline with an auger bit. Use the chisel to remove the rest and to finish the mortise to size and shape. Shallow recesses, such as for lock strike plates, can be made with a chisel by a series of close cross-grain cuts (within Sr knife outline), followed by paring cuts.
