M.a. Ford 27837530B Square End Mill 3/8 in 5 Flute Carbide

Product Description

The M.A. FORD 27837530B is a single-end square end mill designed for high-performance material removal in demanding machining environments. Built from micrograin solid carbide, it delivers the rigidity and edge retention required when cutting steel, stainless steel, cast iron, and high-temperature alloys. The tool features a 3/8 inch diameter with a matching 3/8 inch shank, a 1-5/8 inch length of cut, and a 3-1/2 inch overall length. An ALtima Blaze AlCrN coating provides elevated oxidation resistance and thermal hardness, extending tool life at higher cutting speeds. This end mill is installed by machinists and CNC operators in job shops, aerospace, and industrial manufacturing settings.

The 27837530B belongs to the M.A. FORD 278 Series and is suited for milling operations on steel (ISO P), stainless steel (ISO M), cast iron (ISO K), and high-temperature alloys (ISO S). Its 40-degree helix angle and variable index geometry promote smooth chip evacuation and reduce chatter, making it appropriate for finishing and semi-finishing passes in vertical and horizontal machining centers. The right-hand cut and right-hand flute spiral are standard for conventional CNC setups. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

Key Features

• Micrograin solid carbide substrate for superior hardness and wear resistance
• ALtima Blaze AlCrN coating for high-temperature oxidation resistance and extended tool life
• 5-flute design increases feed rate capability compared to 4-flute equivalents in finishing applications
• Variable index flute spacing reduces harmonic vibration and chatter
• 40-degree helix angle promotes efficient chip evacuation in ferrous and exotic materials
• Centercutting geometry allows direct plunge milling without a pre-drilled entry point

Compatibility

Designed for use on steel, stainless steel, cast iron, and high-temperature alloys (ISO material codes P, M, K, and S). Fits standard 3/8 inch collets and tool holders in CNC machining centers and manual mills.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and spindle locked. Ensure the collet or end mill holder is clean and free of debris before seating the 3/8 inch shank. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear on carbide tooling. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
