Accupro 310207 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 310207 is a solid carbide corner radius end mill designed for precision milling operations in demanding machining environments. It features a 3/8 inch diameter, a 1/2 inch length of cut, and a 2 inch overall length. The 0.020 inch corner radius reduces stress concentrations at the cutting edge, extending tool life in high-feed applications. An AlCrTiN coating provides thermal resistance and wear protection, making this end mill well suited for hardened steels, stainless alloys, and other difficult-to-machine materials. Machinists and CNC operators install this tool in standard 3/8 inch collet or end mill holders.

The 310207 is intended for use in CNC machining centers and manual mills requiring a centercutting, single-end tool capable of plunge entry. Its four-flute, right-hand spiral configuration supports slotting, profiling, and finishing passes. The variable index geometry helps reduce harmonic chatter during extended cuts. The micrograin solid carbide substrate provides the rigidity needed for close-tolerance work in production and job-shop environments alike. This is a single-end tool from the ACCUPRO HS series, sold individually.

Key Features

• AlCrTiN coating for high-temperature wear resistance in ferrous and hardened materials
• 0.020 inch corner radius reduces edge chipping and extends tool life at part corners
• Four flutes with variable index geometry to reduce vibration and improve surface finish
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate for rigidity and dimensional stability
• Right-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 3/8 inch collet chucks and end mill holders used in CNC machining centers and knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify runout with a dial indicator after seating to confirm concentricity before beginning a cut.
