M.a. Ford. 15739370A Square End Mill 0.3937 in 6 Flute Carbide

Product Description

The M.A. FORD. 15739370A is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. With a 0.3937 inch (10 mm) cutting diameter, a 0.9843 inch (25 mm) length of cut, and 6 helical flutes set at a 45-degree helix angle, this tool delivers efficient chip evacuation and stable cutting action. The ALtima coating provides wear resistance and thermal protection. It is a single-end, center-cutting tool with a right-hand cut and right-hand flute direction, suitable for slotting, profiling, and peripheral milling in production environments.

This end mill is built for use on CNC machining centers and manual mills where high material removal rates and surface finish quality are required. The Series 157 designation places it within a geometry optimized for materials including hardened steels, stainless steels, carbon steels, and high-temperature alloys, as indicated by the primary workpiece material codes H, M, P, and S. The straight-cylindrical shank fits standard collet chucks and end mill holders used in most vertical and horizontal machining setups.

Key Features

• Solid carbide micrograin substrate for rigidity and edge retention
• ALtima coating for enhanced wear resistance and heat management
• 45-degree helix angle for aggressive chip flow and reduced cutting forces
• 6 flutes for improved surface finish and feed rate capability
• Center-cutting geometry allows plunge milling entry
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use in machining operations on workpiece materials classified under codes H (hardened steels), M (stainless steels), P (carbon and alloy steels), and S (high-temperature alloys and titanium). Fits standard straight-bore collet chucks and end mill holders accepting a 0.3937 inch (10 mm) shank.

Installation Notes

Installation is performed by qualified machinists or CNC operators. The spindle must be fully stopped and the machine locked out before tool changes. Torque the collet nut or set screw to the tool holder manufacturer's specification using calibrated tooling. Confirm runout with a dial indicator after clamping before beginning a cut to protect both the tool and the workpiece.
