Accupro 12181543 Corner Radius End Mill 3/4 in 2 Flute Ticn

Product Description

The ACCUPRO 12181543 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining applications. It features a 3/4 inch diameter with a 0.02 inch corner radius and a 1-1/2 inch length of cut, making it well suited for slotting, contouring, and peripheral milling where a defined edge radius is required. The tool carries a TiCN (Titanium Carbonitride) coating for improved wear resistance and surface hardness. With a 40-degree helix angle and micrograin carbide substrate, it delivers clean chip evacuation and consistent cutting performance across a range of ferrous and non-ferrous materials.

This end mill is intended for use in CNC machining centers and manual knee mills across job shops, tool-and-die operations, and production machining environments. The single-end, centercutting design allows for plunge entry and direct slot milling without a pre-drilled pilot hole. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling setups. Machinists working with steel, stainless, cast iron, and similar materials will find the TiCN coating and micrograin carbide construction appropriate for moderate-to-aggressive feed rates.

Key Features

• 0.02 inch corner radius reduces stress concentration and improves edge life at part corners
• TiCN coating provides increased hardness and lubricity over uncoated carbide
• Micrograin solid carbide substrate for rigidity and edge retention
• 40-degree helix angle promotes efficient chip evacuation during deep cuts
• Centercutting design enables direct plunge milling without a pre-drilled hole
• 3/4 inch shank diameter for secure tool holding in standard ER or side-lock holders

Compatibility

Designed as an OEM-style solid carbide corner radius end mill suitable for standard 3/4 inch tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque wrench when tightening collet nuts or set screws to manufacturer-specified values for the holder being used. Verify runout with a dial indicator after installation before beginning any cutting operation.
