No, this section isn t about hand-to-hand combat training from basic training Masters in the art of shop often make holes in the material they re working with in order to build that perfect birdhouse (or whatever else they re working on) These holes can be done with a variety of tools, which are covered in the following sections

Twist drills use drill bits, which are round pieces of steel shaped in a spiral, to create holes Drill bits are attached to a drill (usually a power drill, but sometimes a hand drill operated by manually turning a crank) The point of the drill bit is sharpened, and the shank is smooth and fits into the drill

A countersink is a drill bit that enlarges the surface of a hole so that a screw head can be accommodated A countersink is used to allow the top of the fastener to be set exactly even with the material to which it s attached Without a countersink, the fastener slightly protrudes from the material to which it s been attached Auger bits bore larger holes They re shaped differently from drill bits They re also much larger Auger bits are most commonly used with a brace for drilling holes in wood Their length varies from 7 to 10 inches

Punches have a sharp end that s placed against the material to be punctured; the other end is struck with a hammer A center punch is used to mark where a drilled hole is to be placed; this keeps the drill bit in position and prevents the drill from jumping to another part of the material Using a Phillips screwdriver as a punch is bad form in the shop world because hitting the handle of a screwdriver with a hammer can damage it (and then you ll get talked about in serious shop circles)

Chisels are used to chip or cut metal or wood Chisels are made of steel and have a sharp cutting edge Metal-cutting chisels have different shapes depending on how they ll be used; cold chisels are flat; round chisels make circular cuts Chisels that cut metal are usually struck with a mallet to make the cut Some wood chisels, called socket chisels, are also struck with a mallet Other wood chisels require only the pressure of your hands Wood chisels also come in different shapes, depending on what they re used for A butt chisel has a short blade and is used for in-close work A mortising chisel has a narrow blade made for chiseling out the narrow mortises in joints A framing chisel has a heavy, strong blade meant for rough work Because you use chisels with other tools and the pressure of your hands, there s a little bit of a risk involved with this tool One slip and these instruments can easily cut large chunks out of your skin, so be careful

Filing and finishing shop tools are used to sharpen the blades of other tools and to smooth the edges of cut metal objects Files come in a range of fineness, and the blades can be cut in different patterns Files also come in different shapes to finish different kinds of objects Here are the different kinds of files: Single-cut files are used for finishing work and sharpening blades Double-cut files are used for rough work Flat files and half-round files are for general purposes Square and round files fit square and round openings Planes are also a type of finishing tool used to prepare wood for final finishing and to fit doors and trim Planes consist of a handle to push with, a knob to guide with, a frame, a sole, and a mouth (where the blade is) Bench planes are used to smooth surfaces Longer planes give a more uniform surface
