Before diving in, there are some terms you need to understand. The illustration
below shows these terms.
First, notice that there are two cutting edges on the tool bit. There is a cutting
edge on the end of the tool bit called the front cutting edge. There is also a
cutting edge on the side of the tool. Between these cutting edges is a rounded
section of cutting edge called the nose.
Side cutting edge The side cutting edge does most of the cutting. As the
tool bit moves along the workpiece the side cutting edge
removes most of the material.
Front cutting edge The front cutting edge cuts when the tool is advanced
into the work.
Nose
The nose is a critical part of the cutting edge, because it
produces the surface finish of the workpiece.
Side rake
The side rake produces the side cutting edge that cuts
into the workpiece.
Side relief
Side relief provides clearance for the side cutting edge.
Without side relief, the side of the tool bit would hit the
workpiece and not allow the cutting edge to penetrate
the workpiece.
