Accupro 12180344 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12180344 is a double-end corner rounding end mill designed for milling radiused edges on metal workpieces. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it delivers high wear resistance and thermal stability in demanding cutting applications. The tool features a 0.1 inch corner radius, a 0.25 inch mill diameter, a 0.05 inch tip diameter, and a 1/4 inch shank diameter. With 2 flutes in a right-hand cutting and flute direction, it is suited for machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This end mill is used in precision machining environments where consistent, repeatable corner radii are required on ferrous and non-ferrous materials. The double-end configuration extends tool life by providing two usable cutting ends. Typical applications include edge profiling, deburring operations converted to milling, and finish-pass corner rounding on steel, stainless steel, and hardened alloy components. It is a standard choice in job shops, production machining cells, and die and mold work.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• AlTiN coating provides high-temperature resistance and reduced tool wear
• Double-end design offers two cutting ends per tool, increasing value per unit
• 0.1 inch corner radius produces consistent, precise edge profiles
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles
• 1/4 inch shank diameter fits widely available collets and end mill holders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers, knee mills, and manual milling machines equipped with 1/4 inch collets or end mill holders accepting a 1/4 inch shank.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. 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 per the machine manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates carbide tool wear.
