Accupro 12182610 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 12182610 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous metals in CNC machining centers and manual mills. It features a 1/2 inch mill diameter, a 0.045 inch corner radius, and a 4-flute spiral configuration with a 40-degree helix angle. The AlTiN coating improves heat resistance and extends tool life in high-temperature cutting environments. With a 1 inch length of cut and 3 inch overall length, this single-end, centercutting tool handles slotting, profiling, and plunge operations. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill suits applications requiring a controlled corner radius to reduce stress concentrations and improve surface finish on machined pockets, slots, and contoured profiles. It is well suited for use in hardened steels, stainless steels, cast iron, and high-temperature alloys where tool wear resistance is a priority. The right-hand flute direction and right-hand cutting geometry are standard for conventional CNC spindle setups. The micrograin carbide substrate provides consistent edge integrity across the full length of cut.

Key Features

• 0.045 inch corner radius reduces edge chipping and improves workpiece surface finish
• AlTiN coating provides thermal barrier for dry or high-speed machining
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Micrograin solid carbide substrate delivers consistent edge sharpness and wear resistance
• Centercutting geometry allows direct plunge entry into workpiece material
• Single-end design with 1/2 inch shank diameter for standard ER and side-lock toolholders

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1/2 inch shank diameter toolholder. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a clean, properly sized collet or toolholder to the full recommended engagement depth before tightening. Verify spindle runout with a dial indicator before commencing cuts, as excessive runout accelerates wear on carbide tooling. Never exceed the tool manufacturer's recommended cutting parameters for the material being machined.
