Accupro 14796276 Corner Radius End Mill 3/16 in 3 Flute

Product Description

The ACCUPRO 14796276 is a solid carbide corner radius end mill designed for precise milling operations where a controlled edge radius and tight tolerances are required. Built from micrograin solid carbide with an AlTiN coating, this tool handles demanding materials including hardened steels, stainless, and high-temperature alloys. The 3-flute geometry provides a balance of chip evacuation and surface finish. With a 0.0150-inch corner radius and a 0.1875-inch (3/16 inch) cutting diameter, it is suited for finish profiling, contouring, and light slotting in confined features. It is installed and used by machinists and toolroom professionals on CNC machining centers and manual mills.

This end mill is intended for miniature and close-tolerance milling applications where corner radius blending is critical to part geometry. The extended reach design, with a 2.25-inch reach length, allows access to deeper features without tool interference. The 4.0-inch overall length and 3/16-inch shank diameter make it compatible with standard collet and end mill holders used in precision machining environments. Typical applications include die and mold work, aerospace component machining, and medical part production where edge condition and dimensional repeatability are prioritized.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds
• 0.0150-inch corner radius blends edges and reduces stress concentration in milled profiles
• 3-flute spiral geometry with right-hand cut and right-hand flute direction
• Extended reach at 2.25 inches allows access to deep pockets and recessed features
• Centercutting design permits plunge entry directly into the workpiece

Compatibility

Designed as an OEM-style miniature corner radius end mill compatible with standard 3/16-inch collet chucks and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists using standard collet or shrink-fit toolholders rated for the 3/16-inch shank diameter. Ensure the holder bore and collet are clean and free of chips before seating the tool. Confirm runout with a dial indicator before cutting, as micrograin carbide tools are sensitive to excessive runout at small diameters. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type.
