Kennametal 6767731 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The KENNAMETAL 6767731 is a solid carbide square end mill designed for high-performance milling in demanding materials. With a 1/16 inch cutting diameter and 4 flutes featuring a variable helix angle of 36 to 39 degrees and variable index geometry, this tool is engineered to reduce chatter and improve surface finish in steel, stainless steel, cast iron, high-temperature alloys, and hardened materials. The AlTiN coating extends tool life in high-heat applications. It is a single-end, center-cutting tool belonging to the HARVI H1TE series from Kennametal, intended for use by machinists and tooling professionals in CNC milling operations.

This end mill is suited for precision milling applications in aerospace, die and mold, and general metalworking environments where small-diameter tooling is required. With a 1/8 inch length of cut, a 1/8 inch straight shank diameter, and a 1-1/2 inch overall length, it fits standard collet chucks and tool holders used in vertical and horizontal machining centers. Its right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle configurations. The material grade KCPM15 is formulated for performance across ISO material groups P, M, K, S, and H.

Key Features

• Solid carbide construction with AlTiN coating for extended tool life in high-heat and abrasive materials
• Variable helix (36 to 39 degrees) and variable index geometry reduce vibration and chatter during cutting
• Center-cutting design allows for plunge entry and versatile toolpath options
• 4-flute spiral flute configuration improves chip evacuation and finish quality
• Compatible with ISO material groups P, M, K, S, and H including hardened materials
• Straight shank at 1/8 inch diameter fits standard collet and end mill holders

Compatibility

Designed for use with standard 1/8 inch collet chucks and end mill holders on CNC vertical and horizontal machining centers. The KCPM15 material grade and AlTiN coating are optimized for steel, stainless steel, cast iron, high-temperature alloys, and hardened materials as specified by the manufacturer for the H1TE series.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is placed in an appropriate safe state before changing tooling. Use a torque wrench and collet nut wrench appropriate to the tool holder system to achieve proper clamping without over-torquing. Verify tool projection and runout with a dial indicator before beginning a cut.
