Accupro 12182671 Corner Radius End Mill 3/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12182671 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 3/4 inch mill diameter with a 0.06 inch corner radius, a 1-1/2 inch length of cut, and a 4 inch overall length. The 40-degree helix angle and TiCN (Titanium Carbonitride) coating deliver improved wear resistance and cutting performance on ferrous and non-ferrous materials. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. It is sold individually and suited for use on CNC machining centers and manual mills by machinists and toolroom professionals.

This end mill is intended for applications requiring a radiused corner rather than a sharp 90-degree edge, reducing stress concentrations in milled pockets, slots, and profiles. The micrograin carbide substrate supports tight tolerances and extended tool life in production and job-shop environments. Typical applications include contour milling, pocket milling, and finishing passes on steel, stainless steel, cast iron, and similar materials where corner geometry control is critical.

Key Features

• TiCN coating for improved hardness and wear resistance compared to uncoated carbide
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry into the workpiece
• Micrograin solid carbide substrate supports precision tolerances and long tool life
• Right-hand flute direction and right-hand cutting for standard CNC and manual spindle setups
• Corner radius tolerance of 0.0015 inches for repeatable radiused edge geometry

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 3/4 inch collet chucks, end mill holders, and shrink-fit toolholders used on 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. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under cutting loads. Verify runout with a dial indicator after tool installation and before beginning a cut.
