M.a. Ford. 11155120 Square End Mill 0.5512 in 4 Flute Carbide

Product Description

The M.A. FORD. 11155120 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.5512-inch (14 mm) cutting diameter and a 1.181-inch (30 mm) length of cut, this single-end tool removes material efficiently across a range of workpiece materials. The 4-flute helical design with a 30-degree helix angle promotes smooth chip evacuation and stable cutting action. Manufactured from micrograin solid carbide with a bright, uncoated finish, it delivers consistent dimensional accuracy and wear resistance in standard-length configurations. A straight-cylindrical shank with a 0.5512-inch diameter ensures secure tool holding in collet or end mill holders.

This end mill is suited for milling operations on a broad range of materials, including hardened steels, cast iron, stainless steel, non-ferrous metals, non-metals, and high-temperature alloys, consistent with M.A. FORD. Series 111 material codes H, K, M, N, P, and S. It is a standard-reach, standard-length tool appropriate for conventional vertical and horizontal milling machine setups, CNC machining centers, and manual knee mills where a 14 mm diameter cutter is specified. It is not configured for extended-reach applications.

Key Features

• 0.5512-inch (14 mm) cutting diameter with a mill diameter tolerance of +0.000 to -0.070 mm
• 4-flute helical geometry with a 30-degree helix angle for smooth chip flow and reduced cutting forces
• Solid micrograin carbide construction for wear resistance and dimensional stability
• Center-cutting capable, allowing plunge entry into workpiece material
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• Bright, uncoated finish suited for use with or without coolant across multiple material types

Compatibility

Rated for workpiece material codes H, K, M, N, P, and S per M.A. FORD. Series 111 classification, covering hardened steels, cast irons, stainless steels, non-ferrous metals, non-metals, and high-temperature alloys. Straight-cylindrical shank fits standard collet chucks and end mill holders sized for 14 mm or 0.5512-inch tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or removing the tool. Secure the straight-cylindrical shank in a properly sized collet or end mill holder to the holder manufacturer's specified clamping procedure. Verify runout with a dial indicator before beginning a production cut to confirm the tool is seated correctly.
