M.a. Ford 17743700A Square End Mill 7/16 in 4 Flute Carbide

Product Description

The M.A. FORD 17743700A is a solid micrograin carbide square end mill engineered for high-performance milling in demanding materials. It features a 0.4375 inch (7/16 inch) cutting diameter, a 0.4375 inch length of cut, and a 2.5 inch overall length. The tool carries an ALtima coating and runs a variable 35/38 degree helix angle with variable index geometry, reducing chatter and improving chip evacuation across a broad range of workpiece materials. With 4 helical flutes and a straight-cylindrical shank, this end mill is suited for machinists running production or precision milling operations on CNC machining centers.

This end mill is designed for milling operations involving materials classified under primary workpiece material codes H, K, M, P, and S, which correspond to hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys. It is centercutting, enabling plunge entry without pre-drilling. The right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups. It is sold as a single-end tool, appropriate for use in toolholders accepting a 0.4375 inch straight-cylindrical shank.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in tough materials
• ALtima coating improves heat resistance and extends tool life in ferrous and exotic alloys
• Variable 35/38 degree helix angle with variable index geometry reduces harmonic vibration and chatter
• Centercutting design allows direct plunge milling without a pilot hole
• 4 helical flutes with right-hand cut and right-hand flute direction for standard CNC applications
• Mill diameter tolerance of +0.000 to -0.003 inches ensures consistent fit and surface finish

Compatibility

Designed for use in CNC machining centers and milling machines accepting a 0.4375 inch straight-cylindrical shank. Compatible with workpiece material codes H, K, M, P, and S as specified by the manufacturer for Series 177 tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or changing tooling. Seat the shank fully in a clean, properly sized collet or toolholder and torque the retention mechanism according to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear on a carbide end mill.
