I've read the instructions, and watched the videos, about sharpening regular HSS bits for the lathe. I think I understand clearance, side rake, and top rake. But I'm confused by a couple of points (no pun intended.)
The lantern-type tool holder puts the bit at an upward angle, about 10 degrees. But the QCTP holders keep the bit flat. Does this change the angles needed for grinding?
Also, I've looked at the Warner HSS insert kits. The inserts are flat. Is the bed angled to add the top relief?
