Cincinnati Tool & Cutter grinder circular cutter overview

Machine tool cutter grinding in my garage machine shop. This video shows basic set up for grinding the helical flutes on an endmill in the standard work head using a finger rest. I also touch on grinding primary and secondary relief angles using the flat and hollow grinds, and indicator drop method for non-tilt head machines. This video is another showing how I apply the cutter grinder for my needs and the ability to further take control of the cutting edges and angles for special applications. The cutter I have in the head I ground with the tooth pointing upward, that is more risky and cant be done with some cutters. It is best to start off with the sharp edge pointing down.
