Accupro 12182423 Corner Radius End Mill 3/16in 4 Flute Ticn

Product Description

The ACCUPRO 12182423 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 3/16-inch diameter, a 0.03-inch corner radius, and a TiCN (Titanium Carbonitride) coating that extends tool life by reducing friction and resisting heat buildup. With four flutes and a 40-degree helix angle, this single-end, centercutting tool delivers smooth chip evacuation and efficient material removal. It is manufactured from micrograin carbide for added hardness and edge retention. Machinists and tool-and-die professionals specify this geometry for profiling, contouring, and finishing work where a sharp, radiused corner profile is required.

This end mill is suited for use in CNC machining centers and manual mills processing ferrous metals, stainless steel, cast iron, and high-temperature alloys where TiCN coating provides a performance advantage over uncoated or TiN-coated tooling. The centercutting design allows plunge entry, making it practical for pocket milling and ramp entry operations. Right-hand flute direction and right-hand cutting orientation are standard for conventional setup on most vertical and horizontal machining centers.

Key Features

• TiCN coating for improved wear resistance and reduced heat buildup compared to uncoated carbide
• Micrograin solid carbide construction for superior edge retention and rigidity
• 0.03-inch corner radius reduces stress concentrations at part corners and extends cutter life
• 40-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design supports plunge milling and ramp entry without a pre-drilled pilot hole
• Single-end configuration; 3/16-inch shank diameter matches mill diameter for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style replacement or direct-specification corner radius end mill for CNC machining centers and manual mills accepting a 3/16-inch shank diameter in standard collet or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures and machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
