M.a. Ford. 12237500 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The M.A. FORD. 12237500 is a solid carbide square end mill designed for precision milling in a wide range of metalworking applications. With a 3/8 inch cutting diameter, 1-1/2 inch length of cut, and a 3-1/2 inch overall length, this tool falls into the extra-long category, giving machinists added reach for deeper pockets and stepped features. The 30-degree helix angle and four right-hand spiral flutes promote efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, it delivers rigidity and edge retention well beyond what high-speed steel tools can offer. The bright, uncoated finish makes it suitable across a broad set of workpiece materials without coating-compatibility concerns.

This end mill is intended for use in CNC machining centers, knee mills, and rigid vertical milling setups. Its material compatibility codes cover cast iron, non-ferrous metals, stainless steel, aluminum, steel alloys, and superalloys, making it a versatile choice for job shops and production floors alike. The straight-cylindrical shank seats directly in standard collet chucks or end mill holders sized for 3/8 inch shank diameter. Single-end construction means the tool is replaced rather than flipped when worn. This is a tool for machinists and CNC operators who need reliable reach and consistent geometry on repeat cuts.

Key Features

• Micrograin solid carbide construction for high rigidity and extended edge life
• 4 right-hand spiral flutes with a 30-degree helix angle for efficient chip evacuation
• Extra-long 3-1/2 inch overall length provides added reach for deep-pocket milling
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Bright, uncoated finish compatible with a broad range of workpiece materials
• Mill diameter tolerance of +0.000 / -0.003 inches for consistent fit in tight-tolerance work

Compatibility

Designed for use with standard 3/8 inch collet chucks or end mill holders in CNC machining centers and manual vertical mills. Compatible workpiece material codes include H, K, M, N, P, and S, covering steel, stainless, cast iron, aluminum, non-ferrous, and superalloy materials as defined by the supplier specification.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight-cylindrical shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer guidelines. Inspect the cutting edges for chips or damage before each use, and confirm runout is within acceptable limits before beginning a cut.
