Accupro 12182886 Corner Radius End Mill 3/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12182886 is a single-end corner radius end mill designed for precision milling in metalworking and machining applications. It features a 3/8 inch diameter with a 5/8 inch length of cut and a 0.045 inch corner radius that reduces stress concentrations at the base of a cut, extending tool and workpiece life. The body is manufactured from micrograin solid carbide and finished with a TiCN coating for improved wear resistance and performance in ferrous and non-ferrous materials. A 40-degree helix angle promotes efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers running vertical or horizontal milling machines.

This end mill is suited for stub-length milling operations requiring tight tolerances and a radiused corner profile. Its centercutting geometry allows plunge entry as well as conventional peripheral and slot milling. The right-hand flute direction and right-hand cutting orientation make it compatible with standard spindle configurations. Typical applications include profiling, contouring, pocketing, and finishing passes on steel, stainless, cast iron, and similar materials where the TiCN coating provides meaningful abrasion resistance.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating improves wear resistance across a range of ferrous and non-ferrous materials
• 0.045 inch corner radius reduces stress risers and extends workpiece and tool life
• 40-degree helix angle promotes chip evacuation during deep or full-width cuts
• Centercutting design allows plunge milling without a pre-drilled entry point
• 4 flutes with right-hand spiral and right-hand cutting direction for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style replacement or direct-use stub-length corner radius end mill for standard 3/8 inch collets, end mill holders, and milling chucks used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before loading or removing the tool. Seat the 3/8 inch shank fully into a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the corner radius and cutting edges for chips or wear before each use, and follow all applicable shop safety and machine guarding practices.
