For a general purpose tool I will angle the tool bit so that about 50-60% of the end of the tool is ground off when the side is done. For illustrative purposes, I have drawn a line to show what I mean. It is useful for new guys to do this as it helps you to align your tool bit to the grinding media.

The first step in creating a tool bit is to grind the front relief. For most work, a relief angle of 10° works well. While you are grinding the front relief, you are also creating the front cutting edge angle. Make this angle about 10° also, so that the corner formed by the front cutting edge and the side cutting edge is less than 90°.

Angles of tool bits can be positive, negative or have no angle at all. Rake Angles. The term rake angle refers to the angle located at the top of the tool bit. A side rake angle dips back from the cutting edge. This can be positive or have no angle. This determines the size, shape and direction of chips coming off the workpiece.

General Sharpening Approach The process of sharpening turning tools can be described using three sequential steps: A. Shape the tool to the desired angles and dimensions. This is usually done with an 80 grit wheel. B. Sharpen the edge with the grinder. Using a 120 grit wheel, or finer, can achieve this step.
