Kennametal 6754900 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The KENNAMETAL 6754900 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 3/8 inch mill diameter with a 0.015 inch corner radius, 5 flutes, and a 1-1/8 inch length of cut. The 35-degree medium helix promotes efficient chip evacuation, and the bright/uncoated finish makes this tool well suited for aluminum, copper, and other non-ferrous workpiece materials. Coolant-through capability supports both roughing and finishing operations. This tool is part of the KOR5 series and is manufactured from submicron carbide grade for consistent edge integrity across demanding production cycles.

This end mill is built for milling non-ferrous metals in machining centers and CNC mills used in production and job-shop environments. The single-end, straight-cylindrical shank with a 3/8 inch shank diameter mounts directly into hydraulic or collet-style toolholders. It is compatible with HC 20M through HC 32M hydraulic sleeves with inch bores. The right-hand flute direction and right-hand cutting direction make it a standard configuration for conventional and climb milling passes on aluminum, brass, and similar materials.

Key Features

• Solid carbide construction from submicron carbide grade for extended tool life
• 0.015 inch corner radius reduces stress concentrations at part edges and improves surface finish
• 5-flute design increases feed rates and material removal efficiency versus 4-flute configurations
• Coolant-through design delivers coolant directly to the cutting zone for thermal management
• Bright/uncoated finish optimized for non-ferrous metals where coating buildup is a concern
• KOR5 series geometry supports combined roughing and finishing in a single tool

Compatibility

Compatible with HC 20M through HC 32M hydraulic sleeves with inch bores. Designed as an OEM-style solid carbide corner radius end mill for non-ferrous metal milling applications in standard 3/8 inch straight-shank toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the end mill. Use a calibrated toolholder with proper runout tolerance to preserve edge geometry and tool life. Verify coolant-through passages in the toolholder are clear and aligned before initiating a cut.
