Accupro 12182848 Corner Radius End Mill 5/16in 4 Flute

Product Description

The ACCUPRO 12182848 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/16-inch diameter with a 0.01-inch corner radius, four right-hand spiral flutes, and an AlTiN coating that extends tool life in high-temperature cutting applications. With a 1/2-inch length of cut and a 2-inch overall length, this stub-length end mill provides rigidity and minimized deflection in tight-tolerance work. It is single-end and centercutting, allowing plunge entry as well as peripheral and face cutting. Machinists and tool-and-die professionals are the primary installers of this tool.

This end mill is suited for milling ferrous and hardened materials in CNC machining centers and manual knee mills. Its AlTiN coating performs well in dry or minimal-lubrication cutting conditions, making it a practical choice for high-speed steel and cast iron applications. The stub flute length and micrograin carbide substrate make it appropriate for finishing passes and detail work requiring tight dimensional control. It is packaged as a single unit and sold individually.

Key Features

• AlTiN coating for extended tool life in high-heat cutting conditions
• Solid micrograin carbide substrate for hardness and wear resistance
• 0.01-inch corner radius reduces stress concentration at the cutting edge
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindle compatibility
• Stub-length flute for improved rigidity and reduced deflection on deep cuts

Compatibility

Designed as a general-purpose corner radius end mill compatible with standard 5/16-inch collets and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder matching the 5/16-inch shank diameter, and verify runout before beginning a production cut. Follow the machine tool manufacturer guidelines for speed and feed recommendations appropriate to the workpiece material.
