General use is for jig grinding, precision
grinding, and profiling of holes. The diamond flute
pattern allows for rapid stock removal and
acceptable finish. Manufactured with a slight back
taper to overcome any tool deflection, the hole
will have parallel walls.
The tool diameter should be approximately 80% of
the hole diameter being ground allowing for
unfinished hole size at start. Proper machine
design and quality along with rigid workpiece
mounting is critical as with any carbide tool.

Workpiece rotation should be approximately ten
percent (10%) of spindle speed.
If chatter develops first insure machine
capability and workpiece mounting. If chatter
persists reduce speed and increase feed.
