Lathe – Grinding tool bits – Blondihacks
Using the 60-grit wheel, grind the long edge first. Hold it flat against the tool rest (which, remember, is at a 10° downward angle) and slide it smoothly back and forth across the entire wheel. When it gets hot enough to burn your fingers, dunk it in the water and continue. The more dead the nerves in your fingers are, the faster this will go.

In the grinding process, the magnitude of the grinding force has a serious impact on the surface quality of the workpiece and the tool life. In order to explore the influence of different grinding parameters on the grinding force in the ultrasonic-assisted grinding process, this paper carried out an ultrasonic-assisted single-grain high-speed grinding experiment.
Recommended grinding wheel for sharpening HSS bits
The secret to grinding high speed steel is to remember that HSS is abrasion and heat resistant. These two properties make it resistant to grinding. A grinding wheel is a cutting tool and the abrasive grains are in effect its cutting teeth. If the abrasive grains are dull from use they wear more then they cut causing friction thus heating the tool.
