Accupro 12182067 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The ACCUPRO 12182067 is a solid carbide corner radius end mill designed for precision milling of metals and hard materials in CNC machining and manual milling applications. The tool features a 1/2 inch cutting diameter with a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life on contoured and profiled cuts. With 3 flutes and a right-hand spiral flute geometry, it delivers efficient chip evacuation and a smooth surface finish. The bright/uncoated finish suits general-purpose ferrous and non-ferrous cutting where coating is not required. Machinists and CNC operators in job shops, production facilities, and tool rooms install this end mill as a standard cutting tool for slot milling, profiling, and ramping operations.

This end mill is suited for single-end use in vertical machining centers, CNC knee mills, and manual milling machines where a 1/2 inch shank toolholder or collet is available. The centercutting design allows plunge entry directly into workpiece material, making it practical for pocket milling and contour work. The micrograin solid carbide substrate provides the rigidity and wear resistance needed for higher feed rates and harder workpiece materials compared to high-speed steel alternatives. This tool is a single-end configuration with no extended reach, keeping deflection to a minimum in standard-depth applications.

Key Features

• 0.045 inch corner radius reduces edge chipping and stress on profiled cuts
• Micrograin solid carbide substrate for rigidity and wear resistance
• 3-flute right-hand spiral geometry promotes efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for general-purpose ferrous and non-ferrous milling
• Single-end configuration minimizes deflection in standard-depth applications

Compatibility

Designed as a standard 1/2 inch shank corner radius end mill for use in any CNC or manual milling machine equipped with a 1/2 inch collet, end mill holder, or toolholder accepting a 1/2 inch straight shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before commencing a cut, and confirm spindle direction is right-hand before engaging the workpiece.
