M.a. Ford 277L3122B Corner Radius End Mill Head 4 Flute

Product Description

The M.A. FORD 277L3122B is a solid carbide corner radius end mill head designed for precision milling operations in ferrous and non-ferrous materials. This single-end tool features 4 helical flutes with a variable helix angle ranging from 38 to 41 degrees, which helps reduce chatter and improve surface finish across a range of cutting conditions. The variable index geometry further distributes cutting forces unevenly to suppress vibration. With a straight shank diameter of 5/16 inches and a right-hand cutting direction, this head suits modular tooling systems used by machinists and tool-and-die professionals in production and job-shop environments.

This end mill head is suited for profiling, contouring, and finishing passes where a corner radius edge form is required to reduce stress concentrations in the workpiece. The solid carbide construction provides the rigidity and wear resistance needed for high-speed machining in hardened steels, stainless alloys, and aluminum. It is intended for use in CNC machining centers and manual mills where a modular end mill system accepts straight-shank replacement heads. Single-end configuration makes it a direct swap-out when the cutting end is worn without discarding the full tool assembly.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• 4 helical flutes with variable helix angle (38 to 41 degrees) to reduce chatter
• Variable index spacing to distribute cutting forces and suppress vibration
• Corner radius end type reduces stress risers and improves part finish
• Right-hand flute direction and cutting direction for standard CNC spindle compatibility
• 5/16 inch straight shank diameter for modular tooling system interface

Compatibility

Designed as a replacement corner radius end mill head for modular tooling systems that accept a straight shank at 5/16 inches. Confirm compatibility with your specific modular head-locking system before installation.

Installation Notes

Installation of end mill heads should be performed by a qualified machinist following the torque and clamping procedures specified by the modular tooling system manufacturer. Ensure the spindle and toolholder are fully de-energized and at rest before changing cutting heads. Inspect the shank seating surface and locking mechanism for wear or debris before assembly. Follow all applicable shop safety protocols and machine guarding requirements during setup.
