Accupro 12180310 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12180310 is a solid carbide corner rounding end mill designed to produce precise radiused edges on ferrous and non-ferrous workpieces. With a 0.031 inch corner radius and a 1/8 inch mill diameter, this double-end tool delivers consistent edge geometry on tight-tolerance parts. The TiCN (titanium carbonitride) coating increases surface hardness and reduces friction, extending tool life in production environments. Its two-flute configuration provides efficient chip evacuation and suits both conventional and climb milling operations. Machinists and toolroom operators typically select this tool for finishing passes on hardened steels, stainless, and aluminum where a clean, controlled radius is required.

This end mill is suited for use in CNC machining centers, manual mills, and high-speed spindle applications. The double-end design doubles usable tool life before replacement, making it cost-effective for shops running repeated corner-rounding operations. At 1/8 inch shank diameter, it fits standard ER collets and small-bore tool holders commonly found in precision machining and die-and-mold work. Right-hand cutting and right-hand flute direction are standard for conventional CNC toolpath strategies.

Key Features

• 0.031 inch corner radius for consistent, repeatable edge rounding
• Solid carbide construction for rigidity and wear resistance
• TiCN coating reduces friction and increases tool longevity
• Double-end design provides two usable cutting ends per tool
• Two-flute geometry promotes efficient chip evacuation
• Right-hand cut and right-hand helix for standard CNC compatibility

Compatibility

Designed for use in standard 1/8 inch collets and tool holders; suitable for CNC machining centers and manual milling machines accepting 1/8 inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention nut to the tool holder manufacturer specification. Inspect the cutting edges under magnification before use and discard any tool showing chipping or coating loss.
