M.a. Ford 12243310C Square End Mill 0.4331 in 4 Flute

Product Description

The M.A. FORD 12243310C is a solid carbide square end mill designed for precision milling operations across a broad range of workpiece materials. It features a 0.4331-inch (11 mm) cutting diameter, a 1.5748-inch (40 mm) length of cut, and a 0.4331-inch straight-cylindrical shank, placing it in the long-length category. The four-flute, right-hand spiral flute geometry runs at a 30-degree helix angle, promoting efficient chip evacuation and smooth cutting action. A TiCN coating reduces friction and extends tool life in demanding applications. This end mill is centercutting, allowing direct plunge entry into the workpiece.

The 12243310C is suited for milling ferrous and non-ferrous materials including hardened steels, cast irons, stainless steels, aluminum alloys, titanium alloys, and high-temperature alloys, corresponding to ISO material groups H, K, M, N, P, and S. Its long-reach geometry makes it appropriate for deeper pocketing, slotting, and profiling operations where a standard-length tool would not reach. It is typically used in CNC machining centers and manual knee mills in job shop, aerospace, and general manufacturing environments. The micrograin carbide substrate supports tight tolerances and repeatable performance in production runs.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating reduces friction and extends tool life across multiple material groups
• 30-degree right-hand spiral flute geometry promotes efficient chip evacuation
• Centercutting design permits direct plunge milling
• Long-length series (Series 122) enables deeper pocketing and profiling passes
• Straight-cylindrical shank fits standard ER collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use tool compatible with standard straight-bore end mill holders and ER collet chucks accepting an 11 mm (0.4331-inch) shank diameter. Rated for ISO material groups H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Ensure the spindle and tool holder are clean and free of debris before seating the shank to the recommended gauge-line depth. Confirm tool runout with a dial indicator before beginning cuts, as excessive runout will accelerate wear on a carbide tool. Consult the machine manufacturer and applicable shop safety procedures before operating at elevated spindle speeds.
