Accupro 12182103 Corner Radius End Mill 5/8 in 3 Flute Ticn

Product Description

The ACCUPRO 12182103 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 5/8-inch diameter with a 0.015-inch corner radius, a 1-1/4-inch length of cut, and a TiCN (titanium carbonitride) coating that improves surface hardness and wear resistance. Manufactured from micrograin solid carbide, this single-end, centercutting tool delivers tight tolerances and consistent performance in demanding cutting environments. It is suited for use by machinists and CNC operators working in job shops, production facilities, and toolrooms.

This end mill is used in milling operations requiring a controlled corner radius to reduce stress concentration and improve surface finish on workpiece edges. The 3-flute, right-hand spiral design balances chip evacuation with cutting performance, making it appropriate for profiling, slotting, and finishing passes. The 5/8-inch shank diameter fits standard collet and end mill holder setups. The 3-1/2-inch overall length provides reach for typical vertical and horizontal milling applications without sacrificing rigidity.

Key Features

• 0.015-inch corner radius reduces edge stress and improves part surface finish
• TiCN coating provides increased wear resistance and surface hardness over uncoated carbide
• Micrograin solid carbide construction for dimensional stability and edge retention
• 3-flute right-hand spiral geometry balances chip clearance and cutting efficiency
• Centercutting design allows plunge entry into workpiece material
• Single-end configuration with 5/8-inch shank for secure tool holding

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 5/8-inch collets and end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before mounting or removing the end mill. Seat the shank fully into the collet or holder and torque to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to confirm proper seating and avoid premature tool wear.
