Accupro 12180336 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12180336 is a solid carbide corner rounding end mill designed to produce consistent, radiused edges on ferrous and non-ferrous workpieces. It features a 0.085-inch corner radius, a 1/4-inch mill diameter, and a double-end configuration that extends tool life by providing two usable cutting ends per tool. With 2 right-hand flutes and a right-hand cutting direction, the tool delivers clean, smooth edge profiles in milling operations. The bright, uncoated carbide construction makes it well suited for a range of general-purpose machining applications where coating compatibility or cost is a consideration.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills performing edge-rounding and profile operations on metal, composites, or plastics. The double-end design is particularly useful in production environments where tooling efficiency and changeover time matter. A 1/4-inch shank diameter fits standard collets and tool holders commonly found in light to medium-duty milling setups. It is typically set up and operated by machinists and CNC programmers working in job shops, maintenance shops, or production facilities.

Key Features

• 0.085-inch corner radius produces a consistent, smooth edge break on workpiece corners
• Double-end design provides two cutting ends per tool, extending usable tool life
• Solid carbide construction offers rigidity and wear resistance compared to HSS alternatives
• Bright, uncoated finish is suitable for general-purpose use across a variety of workpiece materials
• Right-hand cut and right-hand flute geometry for standard milling spindle direction
• 1/4-inch shank diameter fits common collet sizes on CNC and manual mills

Compatibility

Designed for use with standard 1/4-inch collets and tool holders on CNC machining centers and manual milling machines performing corner-rounding and edge-profiling operations.

Installation Notes

This tool is installed and operated by qualified machinists. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism according to the machine manufacturer's specifications. Verify tool runout with a dial indicator before beginning production cuts, as excessive runout will accelerate tool wear and degrade edge quality.
