M.a. Ford. 17739301A Corner Radius End Mill 10mm 4 Flute

Product Description

The M.A. FORD. 17739301A is a solid carbide corner radius end mill designed for high-performance milling across a range of ferrous and exotic materials. Built to Series 177 specifications, this single-end, centercutting tool features a 10 mm cutting diameter, a 0.5 mm corner radius, and four flutes with a variable helix geometry ranging from 35 to 38 degrees. The ALTiN (ALtima) PVD coating provides thermal resistance and extended tool life when cutting steel, stainless steel, cast iron, and superalloys including titanium. Straight-cylindrical shank design ensures compatibility with standard toolholders used in CNC machining centers.

This end mill is suited for both roughing and finishing operations on ferrous metals and high-temperature alloys. The short flute length and normal pitch make it appropriate for stable, vibration-resistant cuts in vertical and horizontal machining centers. Applications include profiling, slotting, and contouring in steel and stainless steel components found in aerospace, automotive, and general manufacturing environments. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life compared to sharp-corner designs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• ALTiN (ALtima) PVD coating improves heat resistance and tool life in dry or semi-dry cutting
• Variable helix (35 to 38 degrees) reduces chatter and harmonic vibration during milling
• 0.5 mm corner radius reduces edge chipping and extends tool life at the cutting corner
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut and right-hand flute spiral for use on standard CNC spindles

Compatibility

Designed for use with standard toolholders on CNC milling machines. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium (Material Application Codes P, M, K, S). Series 177 design; confirm toolholder bore and runout tolerance before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the straight-cylindrical shank in a precision toolholder and verify runout before cutting. Ensure the machine spindle is fully stopped and the control is in an idle or E-stop state before changing tooling. Do not exceed manufacturer-recommended speeds and feeds for the specific workpiece material and depth of cut.
