M.a. Ford. 27850070B Square End Mill 0.5 in 5 Flute Carbide

Product Description

The M.A. FORD. 27850070B is a solid carbide square end mill designed for high-performance milling operations in metal, alloy, and composite materials. With a 0.5-inch mill diameter and a 3.25-inch length of cut, this tool handles deep-pocket and long-reach applications where rigidity and heat resistance are critical. The AlCrN (aluminum chromium nitride) coating extends tool life by reducing thermal wear at high cutting speeds. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is installed and run by machinists and tool-and-die professionals on CNC milling centers and manual knee mills.

This end mill is suited for production and job-shop environments requiring aggressive material removal with consistent surface finish. The 5-flute configuration balances chip load capacity with cutting stability, making it effective on steels, stainless alloys, and harder workpiece materials. The variable index geometry reduces harmonic vibration during cuts. With a 6-inch overall length and a 0.5-inch shank diameter, it fits standard ER and side-lock toolholders common in vertical and horizontal machining centers.

Key Features

• AlCrN coating for high-temperature wear resistance and extended tool life
• 5 flutes with variable index geometry to reduce chatter and vibration
• 40-degree right-hand helical flutes for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and edge retention
• Center-cutting design allows plunge entry into workpieces
• 3.25-inch length of cut supports deep-pocket and long-reach milling

Compatibility

Designed as a standard-length solid carbide square end mill with a 0.5-inch shank diameter, compatible with ER collet chucks, side-lock holders, and shrink-fit toolholders accepting 0.5-inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Ensure the shank seating depth meets toolholder manufacturer minimums to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping before initiating a cut. Follow the end mill manufacturer feed and speed recommendations for the specific workpiece material and coating type.
