Corner Radius VI-Pro End Mills These mills are TITAN's high performance carbide end mills designed with variable flute index and coated with AlCro-Max (AlCrN) PVD coating. They are specifically engineered for the highest metal removal rates in alloy steels, stainless steels, cast irons, high temp alloys, and titanium. They have a corner radius which strengthens the edge for higher feed rates. The variable index design reduces harmonic chatter which increases edge life. They can be used in all slotting, roughing, finishing and profiling operations. Available in 4, 5, and 6 flutes Available in Stub, Standard, Long, and Extra Long Lengths Corner radii: .015", .030", .060", .090", .120", .190" Diameters: 1/8" - 1" V42SR 4 Flute Stub Length V52SR 5 Flute Stub Length V62SR 6 Flute Stub Length V42RR 4 Flute Standard Length V52RR 5 Flute Standard Length V62RR 6 Flute Standard Length V42LR 4 Flute Lo...
