Accupro 12179677 Corner Radius End Mill 3/8 in 3 Flute Ticn

Product Description

The ACCUPRO 12179677 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 3/8-inch mill diameter, a 0.02-inch corner radius, and a TiCN (titanium carbonitride) coating, this tool delivers improved wear resistance and longer tool life compared to uncoated carbide. The micrograin carbide substrate supports tight tolerances and consistent edge integrity at elevated cutting speeds. It features a single-end, centercutting design with a right-hand flute direction and right-hand cutting direction. This tool is installed and operated by machinists and CNC tool-and-die professionals working in production and precision machining environments.

This end mill is suited for slotting, profiling, and contouring applications where a radiused corner is required to reduce stress concentrations or meet part geometry specifications. The stub length configuration and 35-degree helix angle make it well-suited for rigid setups in vertical machining centers and manual mills. The TiCN coating is particularly effective when cutting steels, stainless steels, and cast iron. It is sold as a single-end tool in individual unit packaging.

Key Features

• 3/8-inch mill diameter with micrograin solid carbide construction for sharp, durable cutting edges
• 0.02-inch corner radius reduces stress at part corners and extends tool life in contouring cuts
• TiCN coating provides enhanced hardness and wear resistance over uncoated carbide
• 3-flute, 35-degree helix design balances chip evacuation and surface finish
• Centercutting geometry allows plunge entry into workpiece material
• Stub length type and 1/2-inch length of cut optimize rigidity in tight setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/8-inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully within a collet or end mill holder to the recommended engagement depth before tightening. Verify spindle speed and feed rate against published carbide cutting data for the workpiece material before operation. Always confirm tool runout with a dial indicator after installation to prevent premature edge wear or part deviation.
