Accupro 12182765 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12182765 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/16 inch (0.1875 inch) diameter with a 0.03 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life on hardened materials. The TiCN coating provides enhanced wear resistance and lubricity compared to uncoated carbide. With a 40-degree helix angle and 4-flute spiral geometry, this single-end, centercutting tool handles both plunge and lateral cutting. It is installed and run by machinists and CNC operators in production and job shop environments.

This end mill is suited for milling slots, pockets, and profiles in ferrous and non-ferrous materials where a corner radius form is required. The stub-length configuration with a 3/8 inch length of cut and 2 inch overall length provides rigidity for high-feed applications in tight setups. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC machining center use. It is a common choice for die and mold work, aerospace components, and precision part manufacturing where corner radius callouts appear on engineering drawings.

Key Features

• 0.03 inch corner radius reduces corner chipping and meets radius-specific drawing requirements
• TiCN coating improves wear resistance and performance on hardened steels and cast iron
• 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate provides rigidity and edge integrity at high surface speeds
• Stub-length geometry minimizes deflection in short-reach milling setups

Compatibility

Designed as a direct-fit replacement for standard 3/16 inch shank corner radius end mills used in CNC machining centers and manual mills with ER or end mill collet toolholding systems.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The machine spindle must be at a full stop and the tool changer or spindle must be locked out before mounting or removing the end mill. Use a calibrated torque wrench and the appropriate collet or end mill holder to achieve proper clamping without damaging the shank. Verify runout with a dial indicator after mounting to stay within tolerance for finish milling operations.
