Set your tool rests down 10°, so that the inside angle between the face of the wheel and the top surface is 100°. This trick will eliminate the need to think in compound angles, which hurt my primitive primate brain. Time to grind a tool bit.

How to Grind Tool Bits Use a bench grinder to sharpen your tool bits. Even an inexpensive bench grinder can do a good job grinding lathe tool bits. In some cases, you might want to purchase a higher quality fine grit wheel. Keep a small cup of water near your grinder. Grinding generates heat, which can cause two problems.
Grinding the end face of the tool. The grinding rest was tipped to give the required end relief angle and the fence adjusted to give the front cutting edge angle. Again the front cutting edge angle was not important, although it is usually set to make the tip and less than 90 º. The relief angle is the critical one.
Begin by dressing the grinding wheel. Next, look up the typical angles for the workpiece material, and then follow the steps in Figure A–2. Dip the tool in coolant frequently to keep it from overheating and annealing. Any discoloration on the bit indicates it may no longer be hardened. If this happens, consider starting over again from the beginning.

This foray into tool grinding theory was educational but the resulting bits cut too well, so well they chattered in the 7x12 and the Rockwell 10". Chatter was a problem on both machines during deep cuts with high feed rate until I limited the feed rate by reducing the side relief (see below) and reduced the width of the cutting section.
Jun 16, 2011· To start grinding, set the tool rest about 2mm from the wheel and hold the drill bit so its centre line is at 59 degrees to the face of the wheel with the cutting lip horizontal. When the cutting lip is brought into contact with the grinding wheel, the drill bit has to
I also recommend buying a copy of Tool and Cutter Sharpening by Harold Hall, Workshop Practice Series #38, which includes much sound advice, along with plans for many easy to build grinding fixtures.
