Accupro 12183023 Corner Radius End Mill 5/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183023 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 5/16-inch diameter with a 1/8-inch corner radius, a 1-1/8-inch length of cut, and a 4-flute right-hand spiral configuration. The micrograin carbide construction provides edge retention and dimensional stability under demanding cutting conditions. At 3 inches overall length with a 5/16-inch shank, this single-end, centercutting tool handles both plunge and peripheral cuts. The bright uncoated finish suits general-purpose ferrous and non-ferrous machining where coating is not required.

This end mill is suited for CNC machining centers and manual mills in job shop, tool-and-die, and production environments. The long flute length and corner radius geometry make it well matched to profile milling, pocketing, and finishing operations where a radiused corner is required on a workpiece edge or floor transition. The right-hand cutting direction and spiral flute type are standard for conventional and climb milling setups on vertical and horizontal spindles.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• 1/8-inch corner radius reduces stress concentrations at milled corners
• 4-flute design balances chip evacuation with surface finish quality
• Centercutting geometry allows direct plunge entry into the workpiece
• Bright uncoated finish suitable for general-purpose ferrous and non-ferrous materials
• Right-hand flute direction and cutting direction for standard spindle setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 5/16-inch collet or end mill holder setups on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists using a collet chuck, end mill holder, or shrink-fit toolholder sized for a 5/16-inch shank. Always bring the spindle to a full stop and isolate machine power before changing tooling. Confirm runout with a dial indicator after seating the tool, and verify corner radius and diameter tolerances against part print requirements before beginning a production run.
