The Challenge

Shorten the cycle time of a roughing operation, improve tool life and increase throughput.

The Solution

H&C Tool Supply's representative recommended that the customer try a 1" diameter Kennametal "Harvi 2" 5-Flute End Mill with a 43 degree flute angle. The End Mill has a PVD coating of ALTIN (KC643M grade). This tool is used with coolant and is excellent for cutting steel, cast iron, stainless steels and titanium.
