M.a. Ford. 12156250 Square End Mill 9/16 Inch Solid Carbide

Product Description

The M.A. FORD. 12156250 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 9/16-inch mill diameter, a 1-1/8-inch length of cut, and a 3-1/2-inch overall length. Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance required for demanding cuts. The uncoated, spiral-flute geometry with a 30-degree helix angle promotes efficient chip evacuation. Centercutting capability allows for direct plunge entry without a pilot hole. Installed by machinists and tooling specialists, this end mill suits CNC machining centers and manual mills requiring consistent dimensional performance.

This end mill is suited for milling ferrous and non-ferrous materials across a range of workpiece material codes including H, K, M, N, P, and S categories, covering cast iron, non-ferrous metals, steel, and heat-resistant alloys. Its regular-length profile makes it appropriate for standard-depth slot milling, profile milling, and peripheral milling operations in job shop and production environments. The straight-cylindrical shank seats securely in standard collet and end mill holders.

Key Features

• 9/16-inch mill diameter with a mill diameter tolerance of +0.000 / -0.003 inches for consistent sizing
• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 30-degree helix angle spiral flute for efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand flute orientation for standard spindle rotation
• Uncoated finish suitable for use with or without cutting fluids depending on material

Compatibility

Part of the M.A. FORD. Series 121 end mill line. Compatible with standard collet chucks and end mill holders accepting a 9/16-inch straight-cylindrical shank. Suited for workpiece materials in M.A. FORD. material code groups H, K, M, N, P, and S.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before changing tooling, de-energize the machine, disengage the spindle, and follow the machine tool lockout procedure per shop safety protocols. Verify shank runout and holder condition prior to mounting to maintain diameter tolerance. Avoid overtightening set-screw holders, as this can damage the straight-cylindrical shank surface.
