Accupro 12182764 Corner Radius End Mill 3/16in 4 Flute

Product Description

The ACCUPRO 12182764 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 with a matching 3/16 inch shank, a 3/8 inch length of cut, and a 2 inch overall length. The 0.02 inch corner radius reduces stress concentration at the cutting edge and improves surface finish in slotting, profiling, and peripheral milling applications. A TiCN coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. This tool is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.

This end mill is suited for stub-length milling applications requiring tight tolerances and a refined corner geometry. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces during side milling and contour work. Right-hand cutting and right-hand flute spiral are standard for conventional CNC spindle rotation. The centercutting capability allows direct plunge entry into workpiece material without a pre-drilled hole. It is appropriate for use in precision shops machining mold components, dies, fixtures, and close-tolerance mechanical parts.

Key Features

• 0.02 inch corner radius reduces edge chipping and improves workpiece surface finish
• TiCN coating provides elevated hardness and thermal resistance for extended tool life
• Micrograin solid carbide construction delivers rigidity and dimensional stability
• 40-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• Single-end, 4-flute configuration balances chip clearance with cutting efficiency

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 3/16 inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists using appropriate collet chucks or end mill holders rated for the 3/16 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank seating depth and runout with a dial indicator before initiating a cut. Follow shop-specific speeds and feeds guidelines for TiCN-coated carbide tooling in the material being machined.
