Accupro 315369 Corner Radius End Mill 3/16 in Solid Carbide

Product Description

The ACCUPRO 315369 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It measures 3/16 inch (0.1875 inch) in diameter with a 5/16 inch (0.3125 inch) length of cut and a 2 inch overall length. The tool features a ZrN (zirconium nitride) coating for improved wear resistance and heat management during cutting. With three flutes, a 37-degree helix angle, and an extended reach design, this end mill is suited for high-speed finishing passes and contour work in tight cavities. It is centercutting, allowing plunge entry directly into the workpiece.

This end mill is used in CNC machining centers and manual mills for finishing and semi-finishing operations on ferrous and non-ferrous materials. The corner radius geometry reduces stress concentration at the cutting edge, making it well suited for mold and die work, aerospace components, and precision part production. The extended reach neck diameter of 0.1781 inch with a 1/2 inch reach length allows access to recessed features without requiring a longer, less rigid tool assembly. It is typically installed by machinists and CNC operators in production and job shop environments.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• ZrN coating reduces friction and extends tool life in demanding cuts
• Corner radius end type minimizes edge chipping and stress at the tool tip
• Centercutting capability allows direct plunge entry into the workpiece
• Extended reach design with 0.1781 inch neck diameter for accessing deep or recessed features
• Right-hand flute direction and right-hand cutting with spiral flute geometry for efficient chip evacuation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter tool holder.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank in a properly sized collet or end mill holder, ensuring the shank is fully seated and the holder is torqued to the machine manufacturer's specification. Verify runout before starting the cut to protect the corner radius edge. Always confirm spindle direction is set to right-hand rotation before engaging the tool.
