		Uncoated Grades
ANSI CLASS	AVERAGE GRAIN SIZE	Grade
C-2	SUBMICRON	15	High strength carbide for low speed machining non-ferrous and high temperature alloys. Excellent for Milling, Turning or Grooving.
C-3	ULTRAFINE	16	For semi-finishing/finishing of non-ferrous alloys at high tempature and moderate speeds and chip loads.
C-2	FINE	18	A general purpose grade for machining cast iron, non-ferrous and high tempature alloys.
C-6	MEDIUM	55	A general purpose steel cutting grade for semifinishing at moderate to high speeds. Great for threading and grooving.
C-7	MEDIUM	65	A high titanium grade carbide for use when edge buildup is a problem and good cosmetics are required. Can be used at moderate to high speeds on carbon and alloy steels. Good for threading, grooving and profiling.
		Coated Grades
		ALUMINUM NITRIDE (PVD)
C-2	SUBMICRON	ALN-200	A tough threading grade with superior edge strength. Suitable for steel as well as chrome and high tempature alloys.
C-3	ULTRAFINE	ALN-202	Finishing and semi-finishing of high tempature alloys, threading, grooving on short chipping materials. Similar to ALN-200 except more abrasion resistant.
C-2	FINE	ALN-205	Finishing grade for for high tempature alloys.
C-6	MEDIUM	ALN-220	Finishing grade for steel
