Accupro 12182593 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 12182593 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining environments. The tool features a 0.5 inch mill diameter, a 1 inch length of cut, and a 0.06 inch corner radius that produces a consistent radiused edge on workpiece profiles. With a 40-degree helix angle and four right-hand spiral flutes, it delivers efficient chip evacuation and smooth cutting action. The bright uncoated finish suits general-purpose applications where coating is not required. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.

This end mill is suited for peripheral and slot milling in ferrous and non-ferrous materials where a corner break or radius is required on the finished profile. The micrograin carbide grade supports use at higher surface speeds than standard carbide grades, making it a practical choice for hardened steels and alloy materials on vertical machining centers and CNC mills. It is a single-end tool with a 0.5 inch shank diameter compatible with standard ER collets, end mill holders, and shrink-fit toolholders.

Key Features

• 0.06 inch corner radius for consistent radiused profiles on machined edges
• Solid micrograin carbide construction for rigidity and wear resistance
• 40-degree helix angle promotes efficient chip evacuation during high-feed passes
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute spiral for standard spindle rotation
• Bright uncoated finish suitable for general-purpose and coolant-assisted applications

Compatibility

Designed as a standard OEM-style corner radius end mill with a 0.5 inch shank diameter, compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems sized for 0.5 inch shanks on CNC vertical and horizontal machining centers.

Installation Notes

This tool is installed by a machinist or CNC operator using appropriate toolholding equipment. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before changing tooling. Confirm runout at the tool tip is within acceptable limits before beginning a cut, as excessive runout accelerates flute wear and degrades corner radius accuracy. Follow the machine manufacturer and tooling manufacturer guidelines for recommended cutting parameters and clamping torque on the toolholder retention knob.
