M.a. Ford 17721810A Square End Mill 0.2187 in 4 Flute Carbide

Product Description

The M.A. FORD 17721810A is a solid micrograin carbide square end mill designed for high-performance milling across a range of workpiece materials. It carries a 0.2187 inch cutting diameter with a 0.4375 inch length of cut and a 0.25 inch straight-cylindrical shank. Overall length is 2.5 inches. The four-flute, variable-helix geometry at 35/38 degrees reduces chatter and improves chip evacuation compared to fixed-helix designs. An ALtima coating adds heat and wear resistance for extended tool life in demanding cuts. Centercutting capability allows plunge entry. Right-hand cut and right-hand flute orientation are standard for conventional CNC machining center use.

This end mill is suited for milling ferrous and non-ferrous metals, heat-resistant alloys, and stainless steels. Primary workpiece material codes H, K, M, P, and S cover hardened steels, cast irons, mild steels, non-ferrous metals, and high-temperature alloys. Typical applications include slot milling, profiling, and contour work on CNC vertical machining centers and milling machines in production and job-shop environments. The variable index flute spacing further minimizes harmonic vibration during long-run cuts. Part of the M.A. FORD Series 177 end mill family.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• ALtima coating for elevated heat and abrasion resistance
• Variable helix (35/38 degrees) and variable index reduce chatter and vibration
• Centercutting design allows direct plunge entry
• Four helical flutes for efficient chip evacuation
• Right-hand cut with straight-cylindrical shank for standard ER and side-lock toolholders

Compatibility

The M.A. FORD 17721810A belongs to Series 177 and is compatible with workpiece material codes H, K, M, P, and S as specified by the manufacturer. It accepts standard 0.25 inch bore toolholders including ER collet chucks and Weldon-style holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine in an e-stop or lockout state. Verify toolholder bore tolerance and runout before use, as the shank diameter tolerance is specified at +0 / -0.00035 inches. Do not exceed manufacturer-recommended speeds and feeds for the target workpiece material. Inspect cutting edges before each use and replace the tool if chipping or wear is observed.
