Kennametal 7077704 Square End Mill 1/2 Inch 6 Flute Carbide

Product Description

The KENNAMETAL 7077704 is a solid carbide square end mill from the Harvi III series, designed for high-performance milling in demanding machining environments. It features a 1/2 inch cutting diameter, six flutes, and a variable helix geometry that reduces chatter and improves surface finish in difficult materials. The AlCrN coating enhances heat resistance and tool life during aggressive cutting operations. Centercutting capability allows for plunge entry, expanding its versatility in milling applications. This tool is installed and operated by machinists and CNC programmers working in job shops, aerospace, die and mold, and general manufacturing.

The 7077704 is suited for high-speed milling of hardened steels, stainless steels, and other difficult-to-machine alloys where tool life and surface integrity are critical. The 1-1/4 inch length of cut and 3 inch overall length make it appropriate for standard-depth slots, pockets, and profiles in vertical and horizontal machining centers. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling spindles. No chipbreaker geometry keeps the cutting edge clean and predictable for finish-pass work.

Key Features

• Six-flute solid carbide construction for rigidity and high material removal rates
• Variable helix design reduces vibration and chatter during aggressive cuts
• AlCrN coating provides elevated heat resistance and extended tool life
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand helical flutes for standard CNC spindle compatibility
• Straight cylindrical shank fits standard ER collets and end mill holders

Compatibility

Designed as an OEM Harvi III series solid carbide square end mill for use in CNC machining centers and manual mills with standard 1/2 inch end mill holders or ER collet chucks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from its holder. Use a properly sized collet or end mill holder to achieve correct runout and clamping torque per the toolholder manufacturer specifications. Inspect the cutting edges for chipping or wear before each use and replace if damage is observed.
