M.a. Ford. 13818756N Square End Mill 3/16 in 3 Flute Carbide

Product Description

The M.A. FORD. 13818756N is a solid carbide square end mill engineered for precision milling in non-ferrous metals and similar materials. It carries a 3/16 inch (0.1875 inch) mill diameter with a 1/4 inch length of cut and a 2 inch overall length. The three-flute, spiral design runs a 36-degree helix angle, promoting efficient chip evacuation and smooth cutting action. The straight cylindrical shank measures 3/16 inch in diameter with an h6 tolerance, keeping runout tight in standard collet chucks. Centercutting geometry allows plunge entry directly into workpieces. This tool is uncoated and suited for machinists and CNC operators working in aluminum, brass, copper, and other non-ferrous stock.

The 13818756N belongs to M.A. FORD. Series 138N, a stub-length extended-reach line designed for applications where a short cutting zone and a reduced neck diameter provide clearance in confined pockets or stepped features. The neck diameter is 0.1770 inch with a 0.7500 inch neck length and a reach length of 0.7500 inch. This geometry makes it a practical choice for pocketing, profiling, and slotting operations on CNC machining centers and manual knee mills handling non-ferrous workpieces in production or job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous milling
• 3-flute spiral design with 36-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Extended reach with 0.7500 inch neck length and reduced 0.1770 inch neck diameter for clearance in deep pockets
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Mill diameter tolerance of +0.0000 to -0.0005 inch for close-tolerance fits

Compatibility

Designed as an OEM-style Series 138N stub-length square end mill for use in CNC machining centers, vertical mills, and similar equipment with standard collet or end mill holders accepting a 3/16 inch straight-cylindrical shank. Primary workpiece material classification is non-ferrous metal (Material Code N).

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention hardware to the tool holder specification. Verify runout with a dial indicator before running at full feed and speed; the h6 shank tolerance supports minimal runout when properly seated in a quality holder.
