Kennametal 6929440 Corner Radius End Mill 6mm 4-flute Altin

Product Description

The KENNAMETAL 6929440 is a solid carbide corner radius end mill engineered for high-performance milling in demanding workpiece materials. It features a 6 mm cutting diameter, 13 mm length of cut, and a 1 mm corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 4-flute, right-hand helical geometry with a 36-degree helix angle supports both roughing and finishing operations in a single tool. An AlTiN PVD coating provides oxidation resistance and hardness retention at elevated cutting temperatures. This end mill is installed by machining professionals and CNC operators working in precision manufacturing environments.

This end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is designed for use in vertical and horizontal machining centers where extended-reach access is required. The straight-cylindrical shank is compatible with ER single angle standard collets. With a 31.98 mm reach length and a neck diameter of 5.64 mm, it can access deeper features without sacrificing rigidity. Material grades and coatings are optimized for ISO material groups P, M, K, S, and H.

Key Features

• 6 mm cutting diameter with 1 mm corner radius for edge strength and surface finish quality
• 4-flute right-hand helical geometry supports roughing and finishing in a single pass
• AlTiN PVD coating delivers heat and oxidation resistance in hard and abrasive materials
• 36-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Extended reach design with 31.98 mm reach length for deep-feature accessibility
• Submicron solid carbide substrate provides wear resistance and dimensional stability

Compatibility

Designed for use with ER single angle standard collets. Compatible with ISO material groups P (steel), M (stainless steel), K (cast iron), S (superalloys and titanium), and H (hard materials). Part of the KENNAMETAL H1TE series; catalog number H1TE4RA0600E013HAR100M.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured to the correct collet size before tightening. Confirm reach length and neck clearance against the workpiece feature depth before beginning a cut. Follow machine tool manufacturer guidelines for runout tolerances and collet torque procedures.
