Accupro 12181299 Corner Radius End Mill 3/16 in 2 Flute

Product Description

The ACCUPRO 12181299 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, this single-end tool features a 3/16 inch diameter, a 0.015 inch corner radius, and a TiCN coating that improves wear resistance and extends tool life in demanding cutting environments. With a 40-degree helix angle and a right-hand spiral flute configuration, the 12181299 delivers efficient chip evacuation and stable cutting performance. It is installed and operated by machinists and CNC tooling professionals working with milling machines and machining centers.

This end mill is suited for finishing and semi-finishing passes where a controlled corner radius is required to reduce stress concentrations at inside corners or to match a specified radius on a workpiece. The 5/8 inch length of cut and 2 inch overall length make it appropriate for shallow-to-medium-depth pocketing and profiling operations. The centercutting design allows it to be plunged directly into the material when the application requires it. It is commonly used in job shops, tool rooms, and production machining environments.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance in abrasive and ferrous materials
• 0.015 inch corner radius reduces stress concentrations at inside corners
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting capable for direct plunge entry
• Right-hand cut, right-hand spiral with 2 flutes for clean finish passes

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard milling machines and CNC machining centers accepting a 3/16 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holding system is clean and free of debris before installing or removing the end mill. Use an appropriate collet or end mill holder sized for a 3/16 inch shank and verify runout before beginning a cut. Follow the tool and machine manufacturer guidelines for speeds, feeds, and depth of cut for the specific material being machined.
