  • Recommended grinding wheel for sharpening HSS bits

    Jun 29 2002 · 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.
