Kennametal 3660436 Corner Radius End Mill 3/4 in 2 Flute

Product Description

The KENNAMETAL 3660436 is a solid carbide corner radius end mill designed for high-performance milling of non-ferrous metals. It features a 3/4 inch cutting diameter, a 1-1/2 inch length of cut, and a 0.12 inch corner radius that reduces stress concentrations at the cutting edge. The 2-flute, right-hand spiral geometry with a high helix angle promotes efficient chip evacuation in aluminum, copper, brass, and similar materials. At 4 inches overall length with a 3/4 inch straight cylindrical shank, this is a short-series tool built for rigidity. Licensed machinists and CNC setup technicians are the primary installers of this tool.

This end mill is suited for roughing operations on non-ferrous metal workpieces in both production and job-shop environments. The centercutting capability allows plunge entry, and the coarse pitch geometry supports aggressive material removal rates. It is designed for use with HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A toolholders. Single-end configuration means the tool is replaced rather than flipped at end of life.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in non-ferrous applications
• 0.12 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• High helix, right-hand spiral flutes promote fast chip evacuation and reduce built-up edge
• Centercutting geometry allows direct plunge milling without a pre-drilled pilot hole
• Bright uncoated finish - no coating interaction concerns with aluminum or other non-ferrous materials
• Straight cylindrical shank compatible with hydraulic, collet, and shrink-fit toolholding systems

Compatibility

Designed for use with HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A toolholders. Intended for non-ferrous metal workpiece materials. Part of the KENNAMETAL ABDF series.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the controller is in a safe state before loading or unloading tooling. Verify shank and bore cleanliness before seating the tool in the holder to achieve proper runout and grip. Consult the toolholder manufacturer torque specifications when tightening hydraulic or shrink-fit assemblies.
