M.a. Ford 13812504 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The M.A. FORD 13812504 is a solid carbide square end mill designed for precise milling of non-ferrous metals and similar materials. Built to Series 138 specifications, it features a 1/8 inch (0.1250 inch) cutting diameter, a 1/2 inch length of cut, and a 1-1/2 inch overall length. The three-flute, spiral-flute geometry with a 36-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a centercutting tool, allowing plunge entry directly into workpiece material. The straight cylindrical shank accepts standard 1/8 inch collets and tool holders. Solid carbide construction provides rigidity and wear resistance suited to tight-tolerance work on aluminum, brass, copper, and other non-ferrous stock.

This end mill is suited for light-duty to medium-duty milling operations on non-ferrous metals in machining centers, CNC mills, and manual knee mills. Its long-reach profile and compact 1/8 inch diameter make it appropriate for slot milling, profiling, and pocket work in confined areas or detailed features. The uncoated carbide substrate is well matched to non-ferrous applications where coating adhesion or heat buildup is less of a concern than edge sharpness and surface finish. Machinists working aluminum plate, bar stock, or extrusions will find this geometry a reliable general-purpose choice for finish and semi-finish passes.

Key Features

• Solid carbide construction for rigidity and dimensional stability during high-RPM cuts
• 3-flute spiral design with 36-degree helix angle for efficient chip evacuation on non-ferrous materials
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• Mill diameter tolerance of +0.0000 / -0.0005 inches for close-tolerance slot and profile work
• Straight cylindrical shank with h6 tolerance for secure collet clamping

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8 inch collets and end mill holders on CNC machining centers and manual milling machines. Primary workpiece material code N indicates optimization for non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for collet torque and runout inspection. Confirm the spindle and tool holder are clean and free of chips or coolant residue before seating the shank. At 1/8 inch diameter, this tool is sensitive to lateral load and deflection — avoid excessive depth of cut or feed rate beyond the calculated chip load for the material. Always power down and lock out the spindle before changing tooling.
