Kennametal 6929449 Corner Radius End Mill 10mm 4 Flute

Product Description

The KENNAMETAL 6929449 is a solid carbide corner radius end mill designed for demanding material removal in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It carries a 10 mm cutting diameter with a 2 mm corner radius and runs four right-hand spiral flutes at a 36-degree helix angle. The AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. At 100 mm overall length with a 22 mm length of cut, this single-end, centercutting tool handles both roughing and finishing operations. It is sized for use with ER single angle standard collets and is part of the H1TE series from KENNAMETAL.

This end mill is suited for CNC machining centers performing profiling, slotting, and contouring in ferrous and high-hardness workpiece materials. The extended reach design, with a 58 mm reach length and a reduced 9.40 mm neck diameter, allows access to deeper features without sacrificing rigidity. The 10 mm straight-cylindrical shank fits standard ER collet toolholders. Applications include mold and die work, aerospace component machining, and general precision part production where corner integrity and surface finish are critical. This tool is installed and operated by machinists and CNC programmers working in production or job shop environments.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, titanium, and hard material grades (P, M, K, S, H)
• 2 mm corner radius reduces stress concentration and extends tool life at part edges
• Extended reach with 58 mm reach length and 9.40 mm neck diameter for deep-feature access
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Normal pitch, right-hand cut, right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use with ER single angle standard collets. Part of the KENNAMETAL H1TE series. Also referenced by manufacturer catalog number H1TE4RA1000E022HAR200M.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout/tagout procedures. Seat the straight-cylindrical shank fully into the ER collet holder and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before first cut, as excessive runout accelerates corner radius wear. Consult the KENNAMETAL H1TE series cutting data recommendations for feeds, speeds, and depth of cut before programming.
