M.a. Ford 13831255 Square End Mill 5/16 Inch Solid Carbide

Product Description

The M.A. FORD 13831255 is a solid carbide square end mill designed for precise milling operations in non-ferrous metals and similar materials. It features a 5/16 inch (0.3125 inch) mill diameter, a 1-1/8 inch length of cut, and a 2-1/2 inch overall length. The three-flute, helical design with a 36-degree helix angle promotes efficient chip evacuation and smooth cutting performance. This is a centercutting tool, allowing plunge entry directly into the workpiece. The uncoated carbide construction suits applications where coating is not required or where the substrate alone meets the demands of the material being machined.

This end mill is suited for milling non-ferrous metals such as aluminum, brass, and copper in both manual and CNC machining centers. Its straight cylindrical shank with h6 tolerance fits standard collets and tool holders used in precision machining environments. The Series 138 designation places it within M.A. FORD's line of general-purpose solid carbide end mills. It is typically installed by machinists and tool-and-die professionals working in job shops, production facilities, and maintenance machining applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous metal cutting
• Three helical flutes with 36-degree helix angle for efficient chip removal
• Centercutting geometry allows direct plunge milling without pre-drilled entry
• Right-hand cut and right-hand flute configuration for standard spindle operation
• Straight cylindrical shank with h6 tolerance for accurate tool holder fitment
• Uncoated substrate suited for non-ferrous and other compatible workpiece materials

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard collet chucks and end mill holders accepting a 5/16 inch straight-cylindrical shank. Primary workpiece material designation is non-ferrous metal (Material Code: N).

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping to minimize tool deflection and premature wear. Follow the machine tool manufacturer and applicable OSHA guidelines for speeds, feeds, and personal protective equipment when operating end mills.
