Use the bench grinder to create a new bevel with a 60-degree angle, being careful not to overheat or burn the metal. Once done with the grinder, use a honing stone to remove the burr on the cutting edge, and create a sharp edge. Make sure to hone each cutting edge evenly, and frequently inspect for nicks or chips.

We advise using a diamond stone. Sharpen the topmost layer. You don't want to modify the cutter's form by sharpening the bevel. This is true for all cutter shapes, including square, diamond, and radiused. Clean up the cutters: Rub a few drops of lapping fluid after laying the stone flat. Place the cutters on the stone.

One of the most common questions I get asked is what angles to use when sharpening lathe tools. There are three main angles you need to worry about when sharpening your lathe tools: the bevel angle, the relief angle, and the side grind angle. The bevel angle is the angle between the cutting edge and the top surface of the tool.
