Machining front cocking serrations on a Ruger P95 pistol slide using a 3/32″ 4 flute TiN/carbide end mill. No coolant, just compressed air for chip clearing and cooling. 6,000 RPM, 2.4 IPM, 0.0001″ IPT chip load, 0.020″ DOC. It ran very smoothly, stayed cool, and produced a very nice surface finish.
