Accupro 12182125 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The ACCUPRO 12182125 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/4 inch mill diameter, a 1-1/2 inch length of cut, and a 0.02 inch corner radius that reduces stress concentrations at the base of a cut and extends tool life on ferrous and non-ferrous workpieces. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. This tool is installed and operated by machinists and CNC programmers working on vertical or horizontal machining centers.

This end mill is suited for profiling, slotting, and contouring applications in job shops, production machining facilities, and tool rooms. The single-end, centercutting design allows plunge entry as well as peripheral cuts. The bright uncoated finish makes it appropriate for use with cutting fluids on aluminum, brass, and other materials where coatings may not be preferred. The 40-degree helix angle promotes efficient chip evacuation during side milling passes.

Key Features

• 0.02 inch corner radius reduces edge chipping and stress at cut transitions
• Micrograin solid carbide construction supports high-speed machining
• Centercutting design allows direct plunge entry without a pre-drilled hole
• 40-degree helix angle improves chip evacuation and surface finish
• Right-hand flute direction and right-hand cutting for standard spindle rotation
• Bright uncoated finish compatible with a wide range of cutting fluid types

Compatibility

Designed as a standard 3/4 inch shank end mill compatible with ER, CAT, BT, and similar toolholders accepting a 3/4 inch straight shank on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before inserting or removing the end mill from the toolholder. Secure the shank to the full recommended contact depth in the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
