Accupro 12182422 Corner Radius End Mill 3/16 in 4 Flute Ticn

Product Description

The ACCUPRO 12182422 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 3/16 inch diameter, a 0.02 inch corner radius, and a TiCN (titanium carbonitride) coating that improves wear resistance and tool life compared to uncoated carbide. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With four flutes and a single-end, centercutting design, this end mill handles slotting, profiling, and plunge operations. Machinists and tool-and-die professionals working with CNC machining centers or manual knee mills are the primary users.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and similar materials where a corner radius is required to reduce stress concentrations or meet part geometry tolerances. It fits typical applications in mold making, die work, and precision component machining. The 5/8 inch length of cut and 2 inch overall length make it appropriate for shallow-to-moderate depth profiling and finishing passes in tight workpiece features.

Key Features

• TiCN coating provides increased surface hardness and reduced friction for extended tool life in ferrous materials
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting geometry allows direct plunge entry into the workpiece
• 0.02 inch corner radius reduces edge chipping and stress concentrations at part corners
• Micrograin solid carbide substrate delivers rigidity and resistance to deflection
• Right-hand flute direction and right-hand cutting for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 3/16 inch collets or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully into a compatible 3/16 inch collet or end mill holder, ensuring the tool is held to the recommended engagement depth per the toolholder manufacturer. Inspect the tool and holder for runout before cutting, as excessive runout accelerates edge wear and degrades surface finish. Do not exceed the tool's rated depth of cut or feed parameters for the workpiece material.
