Accupro 12183462 Corner Radius End Mill 3/16 in 4 Flute Ticn

Product Description

The ACCUPRO 12183462 is a solid carbide corner radius end mill designed for precision milling operations where controlled edge geometry and surface finish are critical. With a 3/16 inch (0.1875 inch) mill diameter and a 0.045 inch corner radius, this tool reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The TiCN coating improves surface hardness and wear resistance compared to uncoated carbide. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and toolroom operators working with steel, stainless, cast iron, and similar materials will find this end mill well-suited to finishing and semi-finishing passes.

This end mill is sized for light to medium material removal in CNC machining centers and manual mills. The 1 inch length of cut and 4 inch overall length suit it to applications requiring moderate reach without sacrificing rigidity. The single-end, centercutting configuration allows for both peripheral and plunge cutting. The micrograin carbide substrate supports the tight tolerances required in die and mold work, aerospace components, and general precision part production where corner radii must be held consistently.

Key Features

• Solid micrograin carbide substrate for rigidity and edge retention
• TiCN coating for improved wear resistance and reduced heat buildup
• 0.045 inch corner radius reduces edge chipping and workpiece stress risers
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut, right-hand flute spiral for standard CNC and manual mill use

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 3/16 inch collets, ER collet chucks, and end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3/16 inch shank fully into the collet or holder and torque the retention mechanism to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear and compromise corner radius tolerance.
