Kennametal 6167536 Corner Radius End Mill 9 Flute Altin

Product Description

The KENNAMETAL 6167536 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding metalworking applications. It features a 1/2-inch mill diameter with 9 flutes in a super close pitch configuration, delivering fine surface finishes with reduced chatter. The 0.38 mm (0.0150 inch) corner radius protects the cutting edge and improves tool life in hard materials. An AlTiN PVD coating enhances heat resistance and wear performance at elevated cutting speeds. Coolant-through capability supports chip evacuation and thermal management during deep cuts. This tool is installed by machinists and CNC operators working in production or job-shop environments.

This end mill is suited for finishing cuts in steel, stainless steel, superalloys, titanium, and hard materials. The short length-of-cut geometry and high helix angle make it effective in rigid setups where surface finish and dimensional accuracy are the priority. It mounts in standard straight-bore end mill toolholders with a 1/2-inch bore. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC machining center use. Single-end configuration means the tool is replaced rather than indexed when worn.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• 9-flute super close pitch design optimized for finishing and fine surface finish
• 0.38 mm corner radius (0.0150 inch) protects cutting edge and reduces stress concentrations
• AlTiN PVD coating provides thermal and oxidation resistance for steel and superalloy cutting
• Coolant-through design aids chip evacuation and controls heat at the cutting zone
• High helix, right-hand spiral flutes with right-hand cutting direction for standard CNC use

Compatibility

Designed for use with standard end mill toolholders accepting a 1/2-inch straight cylindrical shank. Primary workpiece materials include steel, stainless steel, superalloys, titanium, and hard materials as designated by material codes P, M, S, and H. Part of the KENNAMETAL FSDE series.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the toolholder. Verify holder bore condition and runout before seating; excessive runout will accelerate wear on a 9-flute finishing tool. Do not use this tool for slotting or plunge entry, as it is a non-centercutting design.
