Accupro 12180350 Corner Rounding End Mill 5/16 in 2 Flute

Product Description

The ACCUPRO 12180350 is a double-end corner rounding end mill designed for machining precise convex radii on workpiece edges. Built from solid carbide with an AlTiN (Aluminum Titanium Nitride) coating, it delivers high wear resistance and thermal stability during high-speed cutting operations. The tool features a 0.118 inch corner radius, a 5/16 inch mill diameter, and a 0.076 inch tip diameter, with two right-hand flutes and a right-hand cutting direction. Solid carbide construction provides rigidity and extended tool life in demanding milling applications. This end mill is installed and operated by machinists and CNC programmers in precision machining environments.

This corner rounding end mill is suited for edge-finishing operations on ferrous and non-ferrous metals, hardened steels, and other materials where a consistent, repeatable radius is required. The double-end configuration doubles usable tool life before replacement. Typical applications include die and mold work, aerospace component finishing, and general precision part manufacturing. The AlTiN coating makes it particularly effective in dry or high-speed machining conditions where heat generation is a concern.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• AlTiN coating provides thermal and oxidation resistance for high-speed and dry cutting
• Double-end design maximizes value by providing two usable cutting ends
• 0.118 inch corner radius for consistent, precise edge rounding
• Right-hand cut and right-hand flute direction for standard CNC and manual milling setups
• 0.076 inch tip diameter accommodates tight-geometry edge profiles

Compatibility

Designed as a standard corner rounding end mill compatible with milling machines and CNC machining centers accepting a 5/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the 5/16 inch shank in a properly sized collet or end mill holder and torque to the tool holder manufacturer specification. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before installing or changing the tool. Verify runout with a dial indicator after seating to confirm proper holding before beginning a cut.
