Accupro 12183008 Corner Radius End Mill 1/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12183008 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. It features a 1/4 inch diameter, a 0.02 inch corner radius, and a TiCN (titanium carbonitride) coating that extends tool life in abrasive cutting conditions. With 4 flutes and a 40-degree helix angle, it delivers efficient chip evacuation and smooth surface finishes. The micrograin carbide substrate provides the rigidity needed for long-reach profiling and finishing passes. This is a single-end, centercutting tool, meaning it can be plunged directly into the workpiece. Machinists and tool-and-die professionals install this type of end mill on CNC machining centers and manual knee mills.

This end mill is suited for finish profiling, slotting, and contouring operations where a radiused corner is required to reduce stress concentrations or meet part print callouts. The long flute length of 1-1/8 inches supports deep-wall finishing in molds, dies, and precision machined components. The right-hand cut and right-hand spiral flute configuration are standard for conventional and climb milling on vertical machining centers. The 3 inch overall length and 1/4 inch shank make it compatible with standard 1/4 inch collets and end mill holders.

Key Features

• 0.02 inch corner radius reduces stress concentrations and meets radiused corner callouts
• TiCN coating improves hardness and wear resistance in abrasive and ferrous materials
• Micrograin solid carbide substrate provides rigidity and edge retention
• 40-degree helix angle promotes efficient chip evacuation and smooth finishes
• Centercutting design allows direct plunge entry into the workpiece
• Long flute length of 1-1/8 inches supports deep-wall profiling and finishing

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 1/4 inch collet chucks and end mill holders on CNC and manual vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended grip length before torquing the retention nut. Verify runout at the cutting edge with a dial indicator before beginning production cuts.
