Accupro 12180328 Corner Rounding End Mill 3/16 in 2 Flute

Product Description

The ACCUPRO 12180328 is a double-end corner rounding end mill designed for precision edge-profiling on metal workpieces. Built from solid carbide and coated with titanium carbonitride (TiCN), it delivers a 1/16-inch radius profile with a 3/16-inch mill diameter. The two-flute, right-hand cutting geometry provides clean material removal on ferrous and non-ferrous metals. At 2 inches overall length and 0.03 pounds, it fits standard toolholders used in CNC machining centers and manual mills. Machinists and tool-and-die professionals rely on this type of end mill to break sharp edges, add uniform radii, and meet tight finishing tolerances on production and prototype parts.

This corner rounding end mill is suited for light to medium-duty milling operations where a consistent edge radius is required. The double-end configuration extends tool life by offering two usable cutting ends. The TiCN coating reduces friction and improves wear resistance compared to uncoated carbide, making it a practical choice for high-cycle runs on steel, stainless, aluminum, and similar materials. The 3/16-inch shank diameter fits collets and toolholders commonly found in both CNC and manual milling setups across job shops and production environments.

Key Features

• 1/16-inch corner radius for precise, repeatable edge profiling
• Solid carbide construction for rigidity and extended tool life
• TiCN coating reduces wear and lowers cutting friction
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand flute direction for standard milling setups
• Lightweight at 0.03 pounds with a compact 2-inch overall length

Compatibility

Designed as a direct-fit replacement-style corner rounding end mill for 3/16-inch collets and toolholders in CNC machining centers and manual milling machines requiring a 1/16-inch radius profile.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the 3/16-inch shank fully in the collet or toolholder and torque the drawbar or nut per the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates carbide wear and reduces finish quality.
