M.a. Ford. 27821800B Square End Mill 7/32 in 5 Flute

Product Description

The M.A. FORD. 27821800B is a single-end square end mill designed for precision milling in ferrous and non-ferrous materials. Built from micrograin solid carbide and coated with AlCrN (aluminum chromium nitride), it delivers high hardness and thermal resistance at elevated cutting speeds. The 7/32-inch (0.2187-inch) diameter and 5-flute geometry provide a balance of chip evacuation and surface finish quality. A 40-degree helical flute angle promotes smooth cutting action and reduces chatter. Licensed machinists and tool-and-die professionals are the primary users of this end mill in production and job-shop environments.

This end mill suits applications in CNC machining centers and manual mills where tight tolerances and clean finishes are required. The 1/4-inch length of cut and 1/4-inch shank diameter make it well-suited for shallow-to-moderate-depth slotting, profiling, and contouring operations. The variable index design helps suppress vibration during interrupted cuts. AlCrN coating extends tool life in hard materials and high-temperature cutting environments, reducing the need for frequent tool changes.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlCrN coating provides thermal and oxidation resistance at high cutting speeds
• 5-flute configuration balances material removal rate with chip clearance
• 40-degree helix angle reduces cutting forces and improves surface finish
• Variable index flute spacing minimizes harmonic vibration and chatter
• Center-cutting capable — supports plunge entry and ramping operations

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 1/4-inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and de-energized before changing tooling. Use a properly sized collet or end mill holder that matches the 1/4-inch shank diameter and torque the retention nut per the machine manufacturer's specification. Inspect the tool shank and holder bore for chips or damage before seating the tool.
