M.a. Ford. 17850032NA Corner Radius End Mill 1/2 in 5 Fl

Product Description

The M.A. FORD. 17850032NA is a solid carbide corner radius end mill designed for high-performance material removal in ferrous and exotic alloys. It carries a 0.5 inch cutting diameter, a 1-3/8 inch length of cut, and a 0.015 inch corner radius that reduces stress concentration at the tool tip. The AlTiN (ALtima PVD) coating provides thermal resistance and oxidation protection at elevated cutting speeds. With 5 close-pitch right-hand spiral flutes and a 38-degree medium helix, this tool handles both roughing and finishing passes in a single setup. Extended reach and a 3-1/8 inch reach length make it suitable for deeper cavity work without requiring a longer shank.

This end mill is built for cutting steel, stainless steel, cast iron, superalloys, and titanium — material codes P, M, K, and S. The single-end, centercutting design allows plunge entry as well as conventional peripheral and slot milling. The straight-cylindrical 1/2 inch shank mounts directly into standard end mill toolholders. It belongs to M.A. FORD. Series 178N and is classified as a long-length type, making it well suited for mold and die work, aerospace component machining, and general production environments where reach and finish quality are both required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN (ALtima) PVD coating for thermal stability and extended tool life in dry or minimal-coolant cutting
• 5 close-pitch flutes with 38-degree medium helix for balanced chip evacuation across roughing and finishing
• 0.015 inch corner radius reduces chipping and improves surface finish at workpiece corners
• Extended reach with 3-1/8 inch reach length and 5 inch overall length for deep-cavity applications
• Centercutting geometry enables direct plunge entry without pre-drilling

Compatibility

Designed for use with standard end mill toolholders accepting a 1/2 inch straight-cylindrical shank. Intended for machining steel, stainless steel, cast iron, superalloys, and titanium (material codes P, M, K, S) on CNC machining centers and manual mills where extended reach is required.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, as runout directly affects corner radius tolerance and surface finish.
