Kennametal 6769687 Square End Mill 4 Flute Altin Solid Carbide

Product Description

The KENNAMETAL 6769687 is a solid carbide square end mill engineered for high-performance metal removal in demanding machining environments. Built to the H1TE series specification, it features a 0.4724 inch (12 mm) cutting diameter matched to a 0.4724 inch (12 mm) shank, a 4-flute spiral geometry with a variable helix angle of 36 to 39 degrees, and a variable index design. The cutting edges carry an AlTiN coating for heat resistance and extended tool life. With a 0.6299 inch (16 mm) length of cut and a 2.874 inch (73 mm) overall length, this is a single-end, right-hand cut tool ready for use in production and job-shop CNC milling operations.

This end mill is targeted at machinists and tooling specialists running CNC vertical or horizontal mills. It is rated for steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, covering ISO material codes P, M, K, S, and H. The AlTiN coating and variable helix geometry make it well suited for interrupted cuts, high-speed finishing passes, and general profiling in tough alloys where heat buildup and vibration are primary concerns. Center-cutting capability allows direct plunge entry without a pre-drilled start hole.

Key Features

• AlTiN coating resists heat and abrasion in steel, stainless, cast iron, high-temp alloys, and hardened materials
• Variable helix (36 to 39 degrees) and variable index reduce chatter and harmonic vibration
• 4-flute spiral geometry balances material removal rate with chip evacuation
• Center-cutting design permits direct plunge milling without a pilot hole
• Solid carbide construction in material grade KCPM15 for rigidity and edge retention
• Single-end configuration; right-hand flute and right-hand cut

Compatibility

Designed as an OEM-style solid carbide square end mill in the KENNAMETAL H1TE series, compatible with standard CNC milling machine spindles accepting a 0.4724 inch (12 mm) round shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the shank in a collet or end mill holder rated for the shank diameter and ensure runout is within acceptable tolerance before cutting. Power down and lock out the spindle before changing tooling. Verify spindle speed, feed rate, and depth of cut against the machine tool builder guidelines and KENNAMETAL H1TE series cutting data before engaging the workpiece.
