Accupro 12179323 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12179323 is a double-end corner rounding end mill designed to produce consistent radius profiles on ferrous and non-ferrous workpiece edges. Constructed from solid carbide, it delivers the rigidity and wear resistance required for high-speed milling applications. The tool features a 0.078-inch corner radius, a 0.25-inch mill diameter, and a 0.094-inch tip diameter. A titanium nitride (TiN) coating reduces friction and extends tool life in production environments. With two right-hand flutes and right-hand cutting direction, this end mill is suited for CNC machining centers and manual mills where edge-breaking and radius generation are required.

This corner rounding end mill is used in machine shops and production facilities where consistent edge radii are critical for part finish, fatigue resistance, or assembly fit. The double-end configuration provides two usable cutting ends, making it an efficient choice for high-volume operations. Typical applications include contouring edges on aluminum, steel, and alloy components in aerospace, automotive, and general metalworking environments. It is installed in standard 1/4-inch collets or tool holders on CNC and manual milling machines.

Key Features

• Solid carbide construction for rigidity and extended wear life in demanding milling operations
• 0.078-inch corner radius generates consistent, repeatable edge profiles
• TiN coating reduces friction and improves tool longevity
• Double-end design provides two cutting ends per tool, maximizing value in production use
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• 0.094-inch tip diameter suits tight-geometry radius work on precision components

Compatibility

Designed for use in standard 1/4-inch collets or end mill holders on CNC machining centers and manual milling machines capable of accepting 1/4-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is de-energized before changing tooling. Secure the shank to the full recommended engagement depth in the collet or end mill holder to prevent pullout under cutting loads. Verify runout with a dial indicator after tool installation before beginning any cutting operation.
