Kennametal 4067332 Corner Radius End Mill 1-1/4 in 4 Flute

Product Description

The KENNAMETAL 4067332 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built to the HPHV series standard, it carries a 1-1/4 inch diameter with a 0.03 inch corner radius and four flutes ground from submicron-grade carbide. The AlTiN PVD coating extends tool life in high-heat cutting environments. With a 2-1/4 inch length of cut and 5 inch overall length, this is a long-reach tool suited for deep-pocket and profiling work. A Weldon flat shank provides positive drive retention in the spindle. Installation and operation are handled by CNC machinists and tool-room programmers.

This end mill is engineered for roughing and finishing operations on steel, stainless steel, cast iron, and hard materials. The extended reach geometry and high-helix flute design promote chip evacuation and reduce deflection during aggressive cuts. Its single-end, right-hand cut, right-hand spiral configuration is standard for vertical machining centers and horizontal mills running conventional or climb cutting strategies. The tool is compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems as specified by the manufacturer.

Key Features

• Submicron-grade solid carbide substrate for wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating provides thermal and oxidation resistance during high-speed dry or near-dry cutting
• 0.03 inch corner radius reduces stress concentration at the cutting edge and improves surface finish at floor radii
• Extended reach design with 2-1/4 inch length of cut supports deep-cavity and long-reach applications
• Weldon flat shank prevents tool pullout under high torque and feed conditions
• Center-cutting capable — supports direct plunge entry without a pilot hole
• Rated for steel, stainless steel, cast iron, and hard materials (ISO material codes P, M, K, H)

Compatibility

Compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems per manufacturer specifications. Designed for use on CNC machining centers accepting a 1-1/4 inch Weldon flat shank. Suited for ISO P, M, K, and H workpiece material classifications including steel, stainless steel, cast iron, and hard materials.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle and toolholder are fully deenergized and at rest before loading or unloading the tool. Seat the Weldon flat fully into the holder bore and engage the set screw against the flat per the toolholder manufacturer torque guidelines. Verify runout at the cutting diameter before committing to production cuts, particularly given the extended reach of this tool.
