Accupro 310545 Corner Radius End Mill 1 in Solid Carbide

Product Description

The ACCUPRO 310545 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1-inch diameter with a 0.030-inch corner radius, a 2-inch length of cut, and a 4-inch overall length. The cutting geometry is four-flute, right-hand spiral with a 38-degree helix angle and variable index for improved chip evacuation and reduced harmonic vibration. An AlCrTiN coating provides thermal resistance and extended tool life in demanding cutting applications. This tool is centercutting and capable of plunge milling. It is sized and specified for professional machinists working in job shops, tool rooms, and production environments.

The ACCUPRO 310545 is suited for milling steel, stainless steel, and high-temperature alloys where corner radius geometry is required to reduce stress concentrations at mold pockets, slots, and contoured surfaces. The single-end configuration and 1-inch shank diameter make it compatible with standard end mill holders and collet chucks used on CNC machining centers and manual knee mills. The micrograin carbide substrate supports the high cutting speeds and feeds typical of modern CNC applications.

Key Features

• 1-inch diameter with 0.030-inch corner radius for reduced edge chipping and improved surface finish at part corners
• AlCrTiN coating for elevated thermal resistance and longer tool life in ferrous and exotic alloy cuts
• Four-flute, right-hand spiral with 38-degree helix and variable index to reduce chatter and improve chip flow
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide substrate for high rigidity and wear resistance
• 2-inch length of cut and 4-inch overall length for reach into moderate-depth pockets and slots

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 1-inch end mill holders, collet chucks, and hydraulic tool holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a full stop and spindle lock engaged. Ensure the holder bore and shank are clean and free of chips or burrs before seating the tool. Verify runout with a dial indicator after clamping to confirm proper seating. Follow applicable shop safety protocols and machine manufacturer guidelines for tool holding torque specifications.
