Technical Information



Grades of Carbide

WhizCut inserts are available in both PVD coated and uncoated Micrograin carbide with hardness over 1700 Hv. The grades are classified as follows:

Stock Standard

8M is an uncoated grade covering ISO groups K10-K20 and M10-M20.

C8 is a coated grade covering ISO groups K05-K20, M05-M20 and P05-P10.

F8 is a TiAIN multicoated grade where extreme heat is developed when machining. Some of the most common inserts are stocked.

Geometry's

All WhizCut Standard Inserts have sharp fully ground cutting edges. The standard geometry's are 8, 12 and 20° cutting edge. The combination of a high positive cutting rake and ground cutting edge makes the WhizCut inserts useful in most types of material. The Micrograin carbide makes it also suitable for Titanium and Super Alloys.

Wiper
Some inserts for axial turning have a narrow edge, a "wiper", parallel to the centre-line of the machine axle. This wiper produces a very smooth surface finish.
