Accupro 12182086 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The ACCUPRO 12182086 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-temperature cutting conditions common in ferrous and hardened material applications. The 0.06 inch corner radius reduces stress concentrations at the cutting edge and produces smooth radiused profiles on workpieces. With a 1/2 inch diameter, 1 inch length of cut, and 3 flutes in a right-hand spiral configuration, this single-end, centercutting tool is suited for both slotting and profiling operations. It is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is used in vertical and horizontal milling centers, CNC machining centers, and manual knee mills where corner radius profiling or blending is required. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action in steel, stainless steel, cast iron, and similar materials. The AlTiN coating extends tool life in dry or minimal-lubrication cutting conditions. The 1/2 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems common in most machine shop setups.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard material cutting
• AlTiN coating provides thermal resistance and extends tool life in dry or high-speed cutting
• 0.06 inch corner radius for profile blending and reduced edge chipping on workpiece corners
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design allows plunge milling capability
• Right-hand cut, right-hand flute spiral for standard spindle rotation

Compatibility

Designed as a standard 1/2 inch shank corner radius end mill compatible with ER collet chucks, end mill holders, and shrink-fit toolholders sized for 1/2 inch shanks on vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended gauge line before tightening to prevent runout and premature tool failure. Verify spindle direction is set to right-hand rotation before engaging the cut.
