Kennametal 6767734 Square End Mill 3/32 in 4 Flute Carbide

Product Description

The KENNAMETAL 6767734 is a solid carbide square end mill engineered for precision milling in demanding metalworking applications. With a 3/32 inch (0.0938 inch) cutting diameter, 3/16 inch length of cut, and a 4-flute helical geometry, it delivers clean, accurate square-shoulder cuts in hardened steels, stainless, and high-temp alloys. The AlTiN finish provides thermal resistance and extended tool life at elevated cutting speeds. Part of the HARVI series, this end mill is a single-end, centercutting design with right-hand cut and right-hand flute direction, suitable for CNC machinists and toolroom applications where tight tolerances and surface finish matter.

This end mill is used in vertical and horizontal milling operations across aerospace, die-mold, and general precision machining environments. Its straight-cylindrical shank fits standard collet and end mill holders in 1/8 inch bore size, making it a practical choice for small-feature milling on CNC machining centers and manual mills. The centercutting capability allows plunge entry into workpieces without a pre-drilled start hole, expanding its utility in pocket milling and contouring operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• AlTiN coating provides oxidation resistance and extends tool life at high cutting temperatures
• 4-flute helical design improves chip evacuation and surface finish quality
• Centercutting geometry allows direct plunge entry into material
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups
• HARVI series construction with consistent geometry for repeatable results

Compatibility

Designed for use in 1/8 inch straight-bore collets, end mill holders, or shrink-fit holders on CNC machining centers and manual milling machines. Fits standard toolholding systems accepting a 0.1250 inch cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified CNC machinist or toolroom technician with the machine powered down and the spindle locked. Ensure the shank is fully seated and properly torqued in the holder per the toolholder manufacturer specifications. Inspect the collet or holder bore for runout before securing the tool, as excessive runout will accelerate wear on a small-diameter end mill. Follow applicable machine guarding and PPE requirements during setup and operation.
