Kennametal 6675742 Corner Chamfer End Mill 10mm 4 Flute

Product Description

The KENNAMETAL 6675742 is a solid carbide corner chamfer end mill engineered for high-performance metal removal in demanding machining environments. Built on the H1TE platform, it features a 10 mm cutting diameter, 22 mm length of cut, and a 0.50 mm chamfer width at a 45-degree chamfer angle. The four-flute, variable-helix geometry with a 36 to 39 degree helix angle promotes chip evacuation, reduces chatter, and enables stable cuts in both roughing and finishing passes. An AlTiN PVD coating improves heat resistance and tool life when cutting abrasive and hard workpiece materials. The 10 mm straight-cylindrical shank makes it compatible with standard collet and milling chuck toolholders used across machining centers and manual mills.

This end mill is suited for a range of milling operations including shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging and recessing. It is designed for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. The centercutting capability allows direct plunge entry without pre-drilling. Single-end configuration makes it a standard drop-in for CNC machining centers and milling machines where precise chamfer edge preparation is required alongside general milling operations. Machinists working in tool rooms, production shops, and aerospace or die-mold environments will find this geometry well-suited to mixed-material programs.

Key Features

• Solid carbide construction with AlTiN PVD coating for extended tool life in hard and abrasive materials
• Variable helix angle (36 to 39 degrees) reduces vibration and improves surface finish across roughing and finishing passes
• Variable index flute spacing further dampens chatter in interrupted and full-slot cuts
• Centercutting design enables direct plunge entry and helical interpolation without a pilot hole
• 0.50 mm chamfer width at 45 degrees integrates edge chamfering with standard end milling in a single tool
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H)

Compatibility

Designed for use in standard straight-bore collet chucks and milling chucks accepting a 10 mm shank diameter. Part of the KENNAMETAL H1TE series; manufacturer catalog number H1TE4CH1000R022HAM. Material grade KCPM15. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and toolholder are fully powered down and locked out before loading or removing the end mill. Verify runout at the shank before committing to a production program, as excessive runout accelerates edge wear on variable-helix tools. Confirm that feed rate, spindle speed, and depth-of-cut parameters match the workpiece material and coating recommendations from the manufacturer before cutting.
