Sgs 77195 Corner Radius End Mill 0.5in 7 Flute Solid Carbide

Product Description

The SGS 77195 is a single-end corner radius end mill engineered for high-performance finishing operations in demanding metalworking applications. Built from micrograin solid carbide and finished with a TM coating, this tool handles steel, stainless steel, cast iron, superalloys, and titanium. The 7-flute, close-pitch geometry produces smooth surface finishes while maintaining chip clearance at elevated feed rates. A 0.0600-inch corner radius protects the cutting edge from chipping and extends tool life in hard and abrasive materials. The variable index design reduces harmonic chatter, making it well-suited for high-speed finishing passes where surface quality is critical.

This end mill fits standard straight-cylindrical end mill toolholders with a 0.5-inch shank. It is sized for CNC machining centers and manual mills used in tool-and-die, aerospace, and general precision machining environments. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium, with rated secondary application in hard materials. The right-hand cut, right-hand spiral flute configuration is the standard orientation for most vertical machining center setups. A chipbreaker along the flute length reduces cutting forces during extended finishing passes.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TM coating reduces friction and thermal buildup during high-speed finishing cuts
• 7-flute close-pitch design delivers fine surface finish and stable tool engagement
• 0.0600-inch corner radius extends edge life and reduces stress concentration at the cutting corner
• Variable index flute spacing minimizes chatter and vibration during finishing passes
• Chipbreaker geometry lowers cutting forces across the full 1.5-inch length of cut

Compatibility

Designed for use with standard end mill toolholders accepting a 0.5-inch straight-cylindrical shank. Part of the SGS Series 77C corner radius end mill family, rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque guidelines. Power down and lock out the spindle before loading or removing the end mill. Confirm shank engagement depth meets the toolholder minimum before tightening. This tool is not center-cutting and is not suitable for plunge entry; use a ramping or helical entry strategy for pocket operations.
