M.a. Ford. 11131250T Square End Mill 5/16 4 Flute Carbide

Product Description

The M.A. FORD. 11131250T is a solid carbide square end mill designed for precision milling operations across a range of workpiece materials. It features a 0.3125 inch (5/16 inch) mill diameter with a 0.8125 inch length of cut and a 2.5 inch overall length. The four-flute, helical design runs at a 30-degree helix angle with right-hand cut and right-hand flute direction. A titanium nitride (TiN) coating improves surface hardness and wear resistance. The micrograin carbide substrate supports tight tolerances and consistent performance in demanding applications. This end mill is installed by machinists and tooling professionals in CNC and manual milling setups.

This end mill suits a broad range of materials, including hardened steels, cast irons, stainless steels, non-ferrous metals, structural steels, and high-temperature alloys, as indicated by material codes H, K, M, N, P, and S. It is center-cutting, allowing plunge entry. The straight-cylindrical shank fits standard collets and end mill holders. It falls within the Series 111 product family and carries a standard length-of-cut classification, making it a direct fit for general-purpose milling work in job shop, production, and maintenance environments.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• Titanium nitride (TiN) coating extends tool life on a wide range of materials
• 30-degree helical flute geometry promotes chip evacuation and smooth cutting action
• Center-cutting design allows direct plunge entry without a pilot hole
• Right-hand cut with right-hand flute direction for standard CNC and manual mill spindles
• Mill diameter tolerance of +0.000 to -0.003 inches ensures consistent fit and finish

Compatibility

Designed for use in standard straight-cylindrical collets and end mill holders accepting a 0.3125 inch (5/16 inch) shank. Compatible workpiece material codes include H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous metals, structural steels, and superalloys.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before commencing a cut, especially on finishing operations where diameter tolerance is critical.
