Kennametal 6754967 Corner Radius End Mill 0.75in 5-flute Carbide

Product Description

The KENNAMETAL 6754967 is a solid carbide corner radius end mill engineered for demanding material removal in non-ferrous metal applications. Part of the KOR5 series, it features a 0.75 inch mill diameter, a 0.12 inch corner radius, and five flutes arranged in a right-hand spiral with a 35-degree helix angle. The single-end design supports both roughing and finishing passes in a single tool, reducing changeover time on CNC machining centers. Coolant-through capability helps clear chips and manage heat at the cutting zone. The bright uncoated finish is suited to non-ferrous workpiece materials where coating adhesion can cause buildup.

This end mill is intended for machining non-ferrous metals such as aluminum alloys and copper-based materials. It is sized for medium-duty CNC milling operations in job shop and production environments. The Safe-Lock shank type provides positive retention in compatible hydraulic chuck systems, making it appropriate for high-speed and high-feed applications where pullout risk must be eliminated. Licensed machinists and CNC setup technicians are the typical installers.

Key Features

• Solid carbide submicron-grade construction for edge stability in non-ferrous cuts
• 0.12 inch corner radius reduces stress concentration and improves surface finish at floor transitions
• Five flutes with normal pitch and medium 35-degree helix balance chip evacuation and rigidity
• Coolant-through design delivers cutting fluid directly to the cutting edge
• Safe-Lock shank prevents tool pullout in high-speed hydraulic chuck setups
• Single-end, right-hand cutting configuration compatible with standard CNC spindle rotation

Compatibility

Designed for use with HC 1/2 through HC 1-1/4 Hydraulic Sleeves Inch with Inch Bores, HC 20M through HC 32M Hydraulic Sleeves Metric with Inch Bores, HC-HSK Form A, and Hydraulic Chuck Standard Line Inch KM63XMZ toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Confirm the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Verify hydraulic chuck clamping pressure meets the toolholder manufacturer specification before initiating a cut. Do not use this end mill on ferrous materials; it is rated for non-ferrous workpieces only.
