M.a. Ford. 11643750 Square End Mill 7/16 in 3 Flute Carbide

Product Description

The M.A. FORD. 11643750 is a solid carbide square end mill designed for material removal and finishing operations in ferrous and non-ferrous machining applications. The mill measures 7/16 inch (0.4375 inch) in diameter with a 1 inch length of cut and a 2-3/4 inch overall length. Three spiral flutes and a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The straight cylindrical shank is 7/16 inch in diameter, providing consistent tool holding in standard end mill holders or collet chucks. Micrograin carbide construction delivers hardness and wear resistance suitable for production environments. This is a single-end, uncoated tool with a right-hand cut and right-hand flute orientation. Licensed machinists and CNC operators are the primary installers.

This end mill is suited for milling slots, pockets, profiles, and contour cuts across a broad range of workpiece materials. The Series 116 designation and primary workpiece material codes H, K, M, N, P, and S indicate compatibility with material groups including hardened steels, cast irons, stainless steels, non-ferrous alloys, long-chipping steels, and high-temperature alloys. Center-cutting capability allows plunge entry directly into the workpiece, making it practical for both roughing and finishing passes in vertical machining centers and CNC mills.

Key Features

• Solid micrograin carbide construction for hardness and long tool life
• 3 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting design permits direct plunge entry into workpiece material
• Right-hand cut and right-hand flute orientation for standard spindle use
• Uncoated finish; suitable for use with cutting fluid or dry machining depending on material
• Mill diameter tolerance of +0.000 / -0.003 inch for consistent dimensional accuracy

Compatibility

The Series 116 end mill is designed for use with workpiece material groups H, K, M, N, P, and S as designated in the input specifications. These groups cover hardened steels, cast irons, stainless steels, non-ferrous alloys, general steels, and high-temperature alloys. The straight cylindrical shank fits standard end mill holders and collet chuck systems accepting a 7/16 inch shank diameter.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power locked out per applicable shop safety procedures. Ensure the collet or tool holder is clean and free of chips before seating the shank. Verify runout after installation using a dial indicator before beginning a cut. Refer to the machine manufacturer and tooling documentation for recommended speeds and feeds for the target workpiece material.
