Kennametal 4046267 End Mill 6mm 4 Flute Altin Solid Carbide

Product Description

The KENNAMETAL 4046267 is a solid carbide roughing and finishing end mill designed for high-performance material removal in precision machining applications. Built on the F4AS series platform, this 4-flute tool features an AlTiN coating that extends tool life under elevated cutting temperatures. The corner chamfer end geometry reduces chipping at the cutting edge and supports both roughing passes and finish cuts in a single tool. With a 6 mm mill diameter and a 38-degree helix angle, it is engineered for right-hand cutting in demanding ferrous and hardened material applications. Machinists and CNC programmers in job shops and production environments rely on this geometry for efficient chip evacuation and consistent surface finish.

This end mill suits vertical and horizontal machining centers running steel, stainless steel, cast iron, and high-temperature alloys. The straight cylindrical shank allows direct installation in ER collet chucks, shrink-fit holders, and hydraulic chucks with a 6 mm bore. The single-end, centercutting design supports plunge entry as well as conventional and climb milling strategies. It is well suited for die and mold work, aerospace component machining, and general production runs where a single tool must handle both stock removal and near-net finishing.

Key Features

• AlTiN coating provides oxidation resistance and hardness at high cutting temperatures
• Corner chamfer end geometry reduces edge chipping and extends tool life on interrupted cuts
• 38-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting capability allows direct plunge entry without a pre-drilled pilot hole
• Right-hand flute direction and right-hand cutting compatible with standard CNC spindle rotation
• F4AS series solid carbide construction delivers rigidity and dimensional stability in tight-tolerance work

Compatibility

Designed as an OEM-style solid carbide end mill replacement for use in standard 6 mm ER collet, shrink-fit, or hydraulic toolholding systems on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Verify that the toolholder bore is clean and free of debris before seating the shank to the full recommended grip length. Always confirm runout with a dial indicator before the first cut. Follow the machine builder and toolholder manufacturer torque specifications when clamping collet nuts or set screws.
