Accupro 12181411 Corner Radius End Mill 3/8 in 2 Flute

Product Description

The ACCUPRO 12181411 is a single-end corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, it delivers rigidity and wear resistance suited to demanding cut conditions. The tool features a 3/8 inch diameter, a 0.06 inch corner radius, and a 7/8 inch length of cut. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes it well suited for applications where coating interaction with the workpiece is a concern. This end mill is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill is used in milling operations on ferrous and non-ferrous metals where a radiused corner profile is required. The centercutting design allows plunge milling in addition to peripheral and slot cuts. With a 3/8 inch shank diameter matching the cutter diameter, it seats directly in standard collets and end mill holders. Typical applications include profiling, contouring, and producing radiused inside corners on milled parts.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life
• 0.06 inch corner radius produces consistent radiused profiles in a single pass
• Centercutting capability allows direct plunge entry into the workpiece
• 40-degree helix angle promotes efficient chip evacuation
• Bright, uncoated finish suitable for a wide range of base materials
• Right-hand cut and right-hand flute spiral for conventional milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard 3/8 inch collets, end mill holders, and shrink-fit tooling systems used in vertical and horizontal CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the machine spindle is fully stopped and all motion is halted before inserting or removing the end mill from the holder. Seat the shank to the recommended insertion depth for the holder style in use and torque the retention mechanism per the holder manufacturer's specification. Inspect the corner radius and cutting edges for chipping before each use, as carbide tools are brittle and sensitive to improper handling.
