Honing Tool Abrasives

Too high of a concentration = loading/glazing
Too high of a concentration = Increased honing force needed, reduced removal rate, broken tooling
Too low of a concentration = Good removal rate, but the tool will wear out prematurely
Long, stringy chips need larger chip clearance, so low concentration is needed
Small chips (cast iron or carbide) processing allows for a higher concentration
Need a balance of good free-cutting action with cost effective tool life
