Accupro 12179665 Corner Radius End Mill 3/16 in 3 Flute Ticn

Product Description

The ACCUPRO 12179665 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 3/16 inch (0.1875 inch) mill diameter with a 0.01 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding cuts. The 35-degree helix angle promotes efficient chip evacuation, and the TiCN coating adds surface hardness and wear resistance. With 3 flutes in a right-hand spiral configuration, this tool balances material removal rate with surface finish quality. It is a single-end, centercutting design, meaning it can plunge directly into workpiece material. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill suits stub-length milling applications where rigidity is a priority over reach. It performs well in steel, stainless steel, cast iron, and other ferrous materials where TiCN coating provides a measurable advantage in tool longevity. The 5/16 inch length of cut and 2 inch overall length make it appropriate for shallow-pocket milling, contouring, and profiling operations on CNC machining centers and manual knee mills. The centercutting geometry also allows it to be used for drilling entry points before peripheral cuts.

Key Features

• TiCN coating improves hardness and wear resistance on ferrous materials
• 0.01 inch corner radius reduces edge chipping and extends tool life at corners
• 35-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge entry into workpiece material
• Micrograin solid carbide construction provides rigidity and dimensional stability
• Right-hand flute direction and right-hand cutting for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 3/16 inch straight shank end mill with a stub-length profile.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down the spindle and confirm it has come to a full stop before changing tooling. Seat the shank fully into the collet or tool holder to the specified engagement depth and torque the retention nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator after seating before beginning any cut.
