There are various sorts of drill bits made especially for wood, because it's soft and easy to cut. If they're used for metal, they'll go blunt very quickly indeed. Wood drills can be flat, in a spade shape. Or they can be a big coarse spiral with a tiny woodscrew thing at the tip. Or they can be cylindrical and short, also with a central pip or screw. Metal drills are simple spirals, and can also be used for wood. | There are various sorts of drill bits made especially for wood, because it's soft and easy to cut.

===Bandsaw=== | |||
There are various sorts of saw blades for the bandsaw intended for wood or metal. Using the wrong kind of blade will, if you're lucky, just break the bandsaw. If not then, well, all kinds of bad things can happen when a fast rotating sharp edged band of metal snaps under stress. | |||
A simple rule is to check the blade against the kind of straight saw you'd use on your chosen material. | |||
If it looks like a hacksaw blade, it's for metal. | |||
If it looks like a woodsaw blade, it's for wood. | |||
Changing the blade on the bandsaw is possible, but should only be done by someone who has the training. | |||
