Accupro 311360 Corner Radius End Mill 1/8 in 5 Flute Carbide

Product Description

The ACCUPRO 311360 is a single-end corner radius end mill designed for precision milling operations in ferrous and hardened materials. Built from solid micrograin carbide and coated with AlCrTiN for heat and wear resistance, this tool handles demanding cutting conditions where tool life is critical. It features a 1/8 inch diameter, a 1/2 inch length of cut, a 0.010 inch corner radius, and a 38-degree helix angle. With 5 flutes and a variable index geometry, it is suited for machinists and tool-and-die professionals who need consistent finish quality and edge stability at higher feed rates.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter profiling, slotting, or finishing passes are required. The center-cutting design allows plunge entry, making it practical for pocketing operations. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC setups. Its 2 inch overall length and 1/8 inch shank diameter make it a direct fit for standard collets and end mill holders sized for small-diameter tooling.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlCrTiN coating provides thermal protection and extends tool life in dry or high-speed cutting
• 5-flute design increases chip load per tooth and improves surface finish
• Variable index geometry reduces harmonic vibration during cutting
• Center-cutting capability allows direct plunge entry for pocketing
• 0.010 inch corner radius reduces stress concentration at the cutting edge

Compatibility

Designed for use with standard 1/8 inch collets and end mill holders on CNC machining centers and manual milling machines. Suitable for profiling and finishing in ferrous metals, alloy steels, and similar materials where AlCrTiN coating performance is appropriate.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line depth and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout on small-diameter carbide tools increases breakage risk.
