Accupro 2500082 Roughing End Mill 5/16 in 4 Flute Carbide

Product Description

The ACCUPRO 2500082 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers high wear resistance and heat tolerance across a broad range of ferrous and non-ferrous workpiece materials. The mill measures 0.3125 inches (5/16 inch) in diameter with a matching 5/16-inch shank, a 1.125-inch length of cut, and a 3-inch overall length. With 4 flutes in a fine-pitch, right-hand cutting and flute configuration, this tool is built for controlled chip load and surface finish during roughing passes. Centercutting capability allows plunge entry where needed.

This end mill is suited for use in CNC machining centers and manual mills in job shop, production, and tool-and-die environments. The long-series length type provides extended reach for deeper cavities or workpiece features where standard-length tooling cannot access. The TiCN coating makes it a strong choice when machining hardened steels, stainless alloys, and cast iron at elevated cutting speeds. It is installed by machinists and CNC operators and held in standard end mill holders, collet chucks, or shrink-fit tooling compatible with a 5/16-inch shank diameter.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention during roughing cuts
• TiCN coating improves wear resistance and reduces friction at the cutting edge
• 4-flute fine-pitch geometry for controlled chip evacuation and smooth roughing passes
• Centercutting design allows plunge milling into workpiece material
• Right-hand cut and right-hand flute direction for standard spindle operation
• Long-series length type extends reach for deeper features and cavities

Compatibility

Designed for use in standard end mill holders, collet chucks, and shrink-fit toolholders accepting a 5/16-inch shank. Suitable for CNC machining centers and manual knee mills where a 5/16-inch roughing end mill with a long-series reach is required.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and locked before loading or unloading the tool. Verify holder runout and shank seating before beginning any cut. Consult machine tool documentation for appropriate clamping torque specifications for the holder type in use.
