Accupro 12180353 Corner Rounding End Mill 1/8 in Radius

Product Description

The ACCUPRO 12180353 is a double-end corner rounding end mill designed to machine precise convex radii on workpiece edges in metalworking and precision machining applications. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this tool delivers hardness and heat resistance suited for demanding cutting operations. It features a 1/8 inch radius, a 5/16 inch mill diameter, and a 5/16 inch shank diameter, with a tip diameter of 0.063 inches. The two-flute, right-hand cutting geometry provides clean edge finishing in milling operations run on CNC machining centers and manual knee mills.

This corner rounding end mill is used in job shops, toolrooms, and production environments where consistent edge radii are required on metal parts. Typical applications include edge prep on steel, stainless, and aluminum components before assembly or finishing. The double-end configuration doubles usable tool life before replacement, making it a practical choice for shops managing tooling costs on repeat operations. Machinists and CNC operators working in aerospace, medical, die-mold, and general precision machining will find this tool suited to their edge-forming needs.

Key Features

• 1/8 inch corner radius for precise, repeatable convex edge forming
• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life in dry or high-speed cutting
• Double-end design provides two usable cutting ends per tool
• Right-hand cutting and right-hand flute direction compatible with standard CNC spindle rotation
• 0.063 inch tip diameter allows tight corner access in complex part geometries

Compatibility

Designed for use in standard 5/16 inch collets or end mill holders on CNC machining centers and manual milling machines requiring a corner rounding end mill with a 1/8 inch radius.

Installation Notes

Installation is performed by machinists or CNC setup technicians using an appropriate collet or end mill holder sized for a 5/16 inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the tool. Verify runout with a dial indicator after mounting to maintain edge quality and tool life. Follow shop-standard feeds and speeds for carbide tooling in the specific workpiece material being cut.
