Kennametal 6754957 Corner Radius End Mill 5 Flute Solid Carbide

Product Description

The KENNAMETAL 6754957 is a solid carbide corner radius end mill designed for precision material removal in non-ferrous metal applications. It features a 0.5-inch mill diameter, a 0.030-inch corner radius, and five flutes arranged in a right-hand spiral with a 35-degree medium helix angle. The cutting length of cut is 1.5 inches, with an overall length of 3.5 inches. Coolant-through capability supports efficient chip evacuation and heat management during demanding cuts. The submicron carbide grade and bright uncoated finish make this tool well-suited for both roughing and finishing passes on aluminum and similar non-ferrous workpiece materials. Licensed machinists and CNC programmers install this tool in precision machining centers.

This end mill is intended for single-end use in non-ferrous metal machining environments, including aluminum, copper, and similar materials where sharp edges and smooth surface finish are critical. It is part of the KOR5 series, which targets high-efficiency milling operations. The Safe-Lock shank design provides secure tool retention in high-speed spindle applications. Compatible toolholding systems listed by the manufacturer include HC-HSK Form A, HC-CV Form AD, and ER Single Angle Standard Collets. Normal pitch and standard length type make this a versatile fit for production and job-shop CNC applications.

Key Features

• 0.030-inch corner radius reduces stress concentration at the cutting edge and extends tool life on non-ferrous workpieces
• Five-flute, right-hand spiral geometry supports both roughing and finishing in a single tool
• Coolant-through design promotes chip evacuation and thermal control at the cutting zone
• Safe-Lock shank provides positive pull-out resistance in high-speed and high-feed toolholders
• Submicron carbide grade delivers consistent edge integrity across extended run cycles
• Bright uncoated finish is optimized for non-ferrous materials where coated tools can cause built-up edge

Compatibility

Compatible toolholding systems as specified by the manufacturer: HC-HSK Form A, HC-CV Form AD, and ER Single Angle Standard Collets. The 0.5-inch Safe-Lock shank diameter is required for proper tool retention.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the control placed in an E-stop or tool-change state before installing or removing the end mill. Ensure the Safe-Lock toolholder is properly matched to the shank diameter and torqued per the toolholder manufacturer specifications. Verify coolant-through passages are clear and that coolant pressure is set appropriately for the spindle and workpiece material before beginning a cut.
