Accupro 12179316 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12179316 is a solid carbide corner rounding end mill designed to produce precise, consistent radius edges on metal workpieces. With a 0.035 inch corner radius and a 1/8 inch mill diameter, it is built for small-feature edge profiling on ferrous and non-ferrous materials. The titanium nitride (TiN) coating improves surface hardness and reduces friction, extending tool life in production environments. Machinist and tool-and-die applications that require repeatable edge breaks or decorative radius profiles on tight-tolerance parts are the primary use case for this tool. The double-end configuration allows the operator to index to a fresh cutting edge when the first end wears, maximizing value per tool.

This end mill is suited for CNC machining centers and manual milling machines operating on aluminum, steel, stainless, brass, and similar materials where a controlled corner radius is required. The right-hand cut and right-hand flute geometry are standard for conventional milling setups. A 1/8 inch shank diameter fits standard collets and end mill holders of the same bore size, making it a straightforward drop-in for most setups requiring a small-diameter corner rounding tool.

Key Features

• 0.035 inch corner radius for precise small-feature edge profiling
• Solid carbide construction for rigidity and wear resistance in hardened and abrasive materials
• Titanium nitride (TiN) coating reduces tool wear and improves chip evacuation
• Double-end design provides two usable cutting ends per tool
• Right-hand cut, right-hand flute geometry compatible with standard CNC and manual mill setups
• 1/8 inch shank diameter fits common collets and end mill holders

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8 inch collets or end mill holders. Suitable for corner rounding operations on ferrous and non-ferrous workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before loading or changing the tool. Seat the shank fully into a clean, undamaged 1/8 inch collet or end mill holder and torque the drawbar or collet nut to the tool holder specification. Verify runout with a dial indicator before beginning a production run to confirm proper seating.
