M.a. Ford. 27850040B Square End Mill 0.5 in 5 Flute Carbide

Product Description

The M.A. FORD. 27850040B is a solid carbide square end mill designed for high-performance milling in demanding cutting applications. It features a 0.5 inch (1/2 inch) cutting diameter and a 5-flute helical geometry with a 40-degree helix angle, providing efficient chip evacuation and a smooth surface finish. The cutting edge is finished with an AlCrN (aluminum chromium nitride) coating, which improves heat resistance and extends tool life in ferrous and hardened materials. This is a single-end, right-hand cutting tool manufactured from micrograin solid carbide stock. It is installed and used by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slotting, profiling, and peripheral milling operations on ferrous metals, hardened steels, stainless steel, and similar materials where heat buildup and tool wear are primary concerns. The variable index flute spacing helps reduce harmonic vibration during deep cuts. With a 2.125 inch length of cut and a 4 inch overall length, it handles extended-reach applications without sacrificing rigidity. The 0.5 inch shank diameter fits standard ER and side-lock toolholders common in vertical and horizontal machining centers.

Key Features

• 0.5 inch cutting diameter with 2.125 inch length of cut for extended reach capability
• 5-flute helical design with 40-degree helix angle for improved chip flow and surface finish
• AlCrN coating for elevated heat resistance and extended tool life in hard and abrasive materials
• Variable index flute spacing reduces chatter and harmonic vibration during aggressive cuts
• Micrograin solid carbide construction provides consistent edge sharpness and rigidity
• Right-hand cut, right-hand flute, centercutting - suitable for plunge entry

Compatibility

Designed as a standard-shank replacement end mill for use in CNC machining centers and manual mills accepting a 0.5 inch shank diameter in ER collet, Weldon side-lock, or shrink-fit toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm the toolholder is clean and free of chips before seating the shank to the recommended engagement depth. Verify runout with a dial indicator after clamping before initiating a cut.
