Kennametal 6767959 Corner Chamfer End Mill 2mm 4-flute Carbide

Product Description

The KENNAMETAL 6767959 is a solid carbide corner chamfer end mill engineered for high-performance material removal in demanding machining environments. Built on the H1TE series platform, it features a 2 mm diameter, 6 mm length of cut, and a 0.1 mm chamfer width at a 45-degree chamfer angle. The AlTiN PVD coating delivers elevated heat resistance and extended tool life when cutting ferrous and difficult-to-machine materials. With a variable helix and variable index geometry, this end mill reduces harmonic vibration and chatter during aggressive cuts. It is a center-cutting design, supporting plunge entry and multi-directional tool paths. CNC machinists and tool-and-die professionals are the primary users of this tool.

This end mill is suited for precision machining operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Applicable operations include side milling, shoulder milling with eased chamfer edges, helical milling, pocketing, trochoidal milling, ramping, slotting, and plunge milling. The 6 mm straight-cylindrical shank provides consistent runout in standard collet and end mill holders. It is rated for both roughing and finishing passes, making it a versatile choice in job shop and production environments where tool changes are a premium concern.

Key Features

• 2 mm cutting diameter with 0.1 mm chamfer width at 45-degree chamfer angle for precise edge breaking
• Solid carbide substrate in KCPM15 material grade for rigidity and wear resistance
• AlTiN PVD coating provides thermal protection during high-speed cuts on ferrous and exotic alloys
• Variable helix and variable index flute geometry reduces vibration and improves surface finish
• Center-cutting design supports direct plunge entry and trochoidal tool paths
• Single-end, 4-flute, right-hand cut and right-hand flute configuration for standard CNC spindle compatibility

Compatibility

Designed for use with steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Primary workpiece material codes P, M, K, S, and H. Intended for use in standard straight-cylindrical collet chucks and end mill holders accepting a 6 mm shank. Also identified by manufacturers catalog number H1TE4CH0200N006HAM.

Installation Notes

Installation and tool changes should be performed by a qualified CNC machinist with the spindle at a full stop and machine power locked out per shop safety procedures. Verify collet bore size and runout with a dial indicator before committing to a production run, especially at small diameters like 2 mm where deflection is a concern. Refer to the KENNAMETAL cutting data recommendations for this series when establishing feed rate, speed, and depth-of-cut parameters. Do not use this tool in manual milling machines not capable of maintaining the speeds and tolerances required for solid carbide tooling.
