Accupro 12180537 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 12180537 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this single-end mill handles demanding cuts in hardened steels, stainless steels, and high-temperature alloys. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and a 0.015 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The 40 degree helix angle promotes efficient chip evacuation and smooth surface finishes. Installed and operated by machinists and CNC tool room technicians.

This end mill is suited for CNC machining centers, vertical mills, and manual milling machines requiring a centercutting, right-hand spiral tool with a 1/2 inch shank. Typical applications include profiling, slotting, and finishing passes in ferrous and non-ferrous metals where edge integrity and dimensional accuracy are critical. The variable index flute spacing helps reduce harmonic chatter during aggressive cuts, making it appropriate for both roughing and finishing strategies.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating for improved heat resistance and tool life in ferrous materials
• 0.015 inch corner radius reduces edge chipping and stress concentration
• 40 degree helix angle promotes efficient chip flow and smooth cutting action
• Variable index flute geometry reduces chatter during high-feed operations
• Centercutting design allows plunge milling capability

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 1/2 inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a properly sized collet or end mill holder, ensuring minimum shank engagement per shop standards before tightening. Verify spindle speed, feed rate, and depth of cut against tool manufacturer recommendations for the specific workpiece material before starting the cut. Inspect the cutting edges and coating condition before each use and remove the tool from service at the first sign of chipping or excessive wear.
