Kennametal 4067262 Corner Radius End Mill 0.625in 4 Flute

Product Description

The KENNAMETAL 4067262 is a single-end corner radius end mill head designed for demanding material removal in steel, stainless steel, cast iron, non-ferrous metals, and hard materials. Built from solid carbide with a PVD-applied AlTiN coating, this tool delivers reliable performance across both roughing and finishing operations. It features a 0.625 inch mill diameter, a 0.030 inch corner radius, and four right-hand spiral flutes with a medium helix and variable index geometry. The HPHV series designation indicates a high-performance, high-velocity design intended for use in production machining environments where tool life and surface finish consistency are critical.

This end mill head is rated for use in steel and stainless steel applications under material codes P and M, as well as cast iron and hard material applications under codes K and H. It mounts on a Weldon flat shank and is designed for use with compatible toolholders. The 3.5 inch overall length and 1.625 inch length of cut make it well suited for moderate-depth slotting, profiling, and contouring operations in CNC machining centers. Machinists and tooling specialists working in job shop or production settings will find this a direct-use replacement or new-setup option in the KENNAMETAL HPHV series.

Key Features

• Solid carbide construction with AlTiN PVD coating for extended tool life in ferrous and hard materials
• 0.030 inch corner radius reduces stress concentration and improves workpiece surface finish
• Variable index geometry minimizes chatter and vibration during aggressive cuts
• Center-cutting capable for direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction with normal pitch for consistent chip evacuation
• Weldon flat shank ensures positive drive and accurate seating in compatible toolholders

Compatibility

Designed for use with toolholders compatible with a 0.625 inch Weldon flat shank. Part of the KENNAMETAL HPHV series; catalog number HPHV625S4163R030. Shank diameter tolerance is h6. Mill diameter tolerance is +0.0000 / -0.0020 inches.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before mounting or removing any end mill head. Verify toolholder bore cleanliness and torque the Weldon flat set screw to the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating a cutting program, particularly for finishing operations where dimensional accuracy is critical.
