Accupro 12182668 Corner Radius End Mill 3/4in 4 Flute Ticn

Product Description

The ACCUPRO 12182668 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/4 inch diameter, a 1-1/2 inch length of cut, and a 0.0200 inch corner radius that reduces stress concentrations at part edges and extends tool life in demanding cuts. The 4-flute, right-hand spiral geometry combined with a TiCN coating provides excellent wear resistance and performance in harder ferrous materials. At 4 inches overall length with a matching 3/4 inch shank diameter, this single-end, centercutting tool handles both plunge and contour operations. It is intended for use by machinists and CNC operators working in production or job-shop environments.

This end mill is suited for milling slots, pockets, and profiles in steel, stainless steel, cast iron, and similar materials where a radiused corner is required for part geometry or fatigue resistance. The 40 degree helix angle promotes smooth chip evacuation and reduces chatter during high-feed passes. The micrograin carbide substrate supports sharp edge retention at elevated cutting temperatures. Typical applications include die and mold work, aerospace component machining, and general precision part production on CNC machining centers and manual knee mills.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating improves wear resistance in ferrous and abrasive materials
• 0.0200 inch corner radius reduces edge chipping and stress concentrations
• 4-flute right-hand spiral design supports high material removal rates
• 40 degree helix angle promotes efficient chip evacuation
• Centercutting capability allows direct plunge entry into workpiece

Compatibility

Designed as an OEM-style replacement or direct fitment corner radius end mill for CNC machining centers and manual mills accepting a 3/4 inch straight shank toolholder.

Installation Notes

This tool is installed and serviced by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and machine is in an energy-isolated state before changing tooling. Seat the 3/4 inch shank fully into a clean, properly torqued collet or end mill holder to prevent runout. Verify corner radius and diameter tolerances against job print requirements before beginning a production run.
