M.a. Ford 277X3122B Corner Radius End Mill Head 4 Flute

Product Description

The M.A. FORD 277X3122B is a solid carbide corner radius end mill head engineered for precision milling applications. Featuring 4 helical flutes with a variable helix angle ranging from 38 to 41 degrees and a variable index design, this head reduces chatter and improves surface finish in demanding cutting environments. Right-hand flute direction and right-hand cutting rotation are standard. Solid carbide construction delivers the hardness and wear resistance required for high-feed operations in ferrous and non-ferrous materials. Machinists and tool-and-die professionals install this head as part of a modular end mill system.

This corner radius end mill head suits CNC machining centers where a modular tooling system is in use. The corner radius end type protects the cutting edge from chipping during profiling, contouring, and slotting passes. Variable helix geometry distributes cutting forces unevenly across the flutes, lowering vibration during long-reach and deep-pocket operations. It is suited for job shops, production machining, and mold-and-die work where tool change frequency and edge consistency are priorities.

Key Features

• Solid carbide construction for hardness and extended tool life
• 4 helical flutes for efficient chip evacuation
• Variable helix angle (38 to 41 degrees) reduces harmonics and chatter
• Variable index spacing distributes cutting forces for improved surface finish
• Corner radius end type protects cutting edges during profiling and contouring
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as a modular replacement end mill head for use with compatible M.A. FORD modular tooling arbors and shanks. Confirm shank interface and diameter specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before mounting or removing any end mill head. Use the appropriate torque wrench and interface tool specified for the modular system to seat the head correctly - do not over-tighten by hand. Inspect the mating interface and threads for wear or contamination before each installation.
