It's a long time since I was taught the names the names but I do sharpen my drill bits, chisels, planes and knives but here goes. 1, looking from the top down is the angle between the cutting edge, looking from the front is the bevel and from the side the downwards angle. 2 Forgotten 3 Forgotten 4 Flute 5 Rake is the front angle, clearance is the side angle on #1 6 Where the saw blade doesn't point into the material, often for cutting ali. 7 Countersink is a small depression to take a screw head, counterbore is a deeper hole 8 Tool steel is harder than high carbon steel 9 Tungsten carbide tooling 10 clearance is wider than the screw and is in the bit your fixing, pilot is smaller than the screw and is in the bit your fixing too. 11 bevel is full depth, chamfer is like an arris 12 Because you pull it over the wood?
