M.a. Ford 13875007R.120 Corner Radius End Mill 3/4 in

Product Description

The M.A. FORD 13875007R.120 is a solid carbide corner radius end mill designed for high-precision milling in non-ferrous metal applications. It features a 3/4 inch cutting diameter, a 2-1/2 inch length of cut, and a 0.12 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in both roughing and finishing operations. With 3 right-hand spiral flutes and a bright uncoated finish, this single-end mill suits machinists and toolroom technicians running aluminum, brass, copper, and similar non-ferrous workpiece materials on CNC machining centers or manual knee mills.

This end mill is built for production and toolroom environments where a combination of roughing and finishing in a single tool pass is required. The Series 138 designation places it in M.A. FORD's standard-reach, straight-shank line. The centercutting geometry allows plunge entry as well as conventional peripheral and slot milling. Its 5 inch overall length and 3/4 inch straight cylindrical shank mount directly into standard collet chucks, end mill holders, and hydraulic toolholders rated for that shank diameter.

Key Features

• 0.12 inch corner radius with tolerance of plus 0.002 / minus 0.002 inches for consistent edge geometry
• Solid carbide construction provides rigidity and wear resistance in non-ferrous metal cutting
• Centercutting design permits direct plunge entry without a pilot hole
• Right-hand cut, right-hand spiral flutes with medium helix for controlled chip evacuation
• Bright uncoated finish suited to non-ferrous materials where coating adhesion or chemical reaction is a concern
• Single-end, normal pitch, no chipbreaker - optimized for smooth surface finish and dimensional accuracy

Compatibility

Designed for use with standard toolholders accepting a 3/4 inch straight cylindrical shank, including collet chucks, end mill holders, shrink-fit holders, and hydraulic chucks. Primary workpiece material is non-ferrous metal.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is secured to the specified pullout torque for the toolholder type before beginning any cut. Confirm runout at the cutting edge with a dial indicator before production use, as excessive runout accelerates corner radius wear on carbide tools. Do not use this tool on ferrous materials, as the uncoated carbide and flute geometry are optimized for non-ferrous applications.
