Kennametal 4046291 Corner Radius End Mill 6mm 5 Flute Carbide

Product Description

The KENNAMETAL 4046291 is a solid carbide corner radius end mill designed for high-performance milling in steel, stainless steel, cast iron, and hard materials. It features a 6 mm cutting diameter, a 13 mm length of cut, and a 0.38 mm corner radius that protects the cutting edge and reduces chipping in demanding applications. The tool carries an AlTiN PVD coating, which improves heat resistance and extends tool life in dry or semi-dry cutting conditions. With 5 flutes and a right-hand spiral flute geometry, it is built for both roughing and finishing passes in a single setup. Licensed machinists and CNC operators use this end mill in production and job-shop environments where surface finish and edge integrity are critical.

This end mill is suited for use in CNC machining centers handling ferrous workpieces including carbon steel, tool steel, stainless steel, cast iron, and hard materials. The straight-cylindrical shank and 6 mm shank diameter make it compatible with ER single angle standard collets. With a 57 mm overall length and standard length-type classification, it fits standard toolholding setups without extended-reach adapters. The UCDE series designation places it in a category optimized for both material removal rate and surface finish quality across a range of ferrous and hard material applications.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating improves thermal stability and oxidation resistance at the cutting edge
• 5-flute design supports higher feed rates and improved surface finish in ferrous materials
• 0.38 mm corner radius reduces stress concentration and edge chipping at workpiece corners
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• Rated for roughing and finishing material removal types in a single tool

Compatibility

Designed for use with ER single angle standard collets. Suitable for machining steel, stainless steel, cast iron, and hard materials as part of the KENNAMETAL UCDE series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Secure the straight-cylindrical shank in a properly sized ER collet and tighten to the collet nut torque specification published by the toolholder manufacturer. Verify runout at the cutting diameter before beginning a production cycle.
