Kennametal 6754958 Corner Radius End Mill 0.5in 5 Flute

Product Description

The KENNAMETAL 6754958 is a solid carbide corner radius end mill designed for high-performance milling in non-ferrous metal applications. It features a 0.5-inch diameter, a 0.06-inch corner radius, and five right-hand spiral flutes arranged in a normal pitch configuration. The cutting length of 1.5625 inches and an overall length of 3.5 inches make it well suited for standard-depth milling operations. Built from submicron carbide grain, this tool delivers precise edge retention without a coating, which is preferred when machining materials like aluminum, copper, and brass where coating adhesion can cause built-up edge. Coolant-through capability is integrated into the design to support chip evacuation and thermal management at the cutting zone.

This end mill is intended for single-end use in both roughing and finishing operations on non-ferrous metals. The Safe-Lock shank style is compatible with HC-HSK Form A, HC-CV Form AD, and ER single angle standard collet toolholding systems, making it adaptable across a range of CNC machining centers. It is part of the KOR5 series and suited for shops running high-speed or standard machining cycles on aluminum alloys and similar materials.

Key Features

• Solid carbide submicron grain construction for consistent edge sharpness in non-ferrous cuts
• 0.06-inch corner radius reduces stress concentration and extends tool life at the cutting edge
• Five right-hand spiral flutes with normal pitch balance chip load and surface finish
• Coolant-through design supports internal chip evacuation and cutting zone cooling
• Safe-Lock shank compatible with HC-HSK Form A, HC-CV Form AD, and ER collet systems
• Bright/uncoated finish optimized for non-ferrous material applications

Compatibility

Compatible toolholding systems include HC-HSK Form A, HC-CV Form AD, and ER single angle standard collets. This end mill is designed for use in CNC machining centers requiring a 0.5-inch shank diameter with Safe-Lock interface.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the spindle before changing tooling. Confirm runout with a dial indicator after seating the tool in the holder to verify concentricity before beginning a cut. Follow the machine manufacturer and toolholder manufacturer specifications for clamping torque and safe operating speeds.
