How to Sharpen the HSS Drill Bit?

You can Sharpen the HSS Drill Bit when the chipping length is below 0.02,” or

drilled holes are out of the tolerance. When the drilling produces more noise is

another sign of sharpening. You can use a file or grinder made with carbide or

diamond. The cutting angle should maintain according to the material requirement.
