Accupro 2500160 Roughing End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 2500160 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 hard, wear-resistant cutting edges suited for high-speed roughing passes on ferrous and non-ferrous materials. The mill measures 7/16 inch (0.4375 inch) in diameter with a 1-inch length of cut and a 2-3/4-inch overall length. With 4 flutes in a fine-pitch, right-hand cutting and flute direction, this tool is optimized for chip evacuation and surface contact during roughing applications. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills where rapid stock removal is the primary objective.

This end mill is suited for horizontal and vertical milling setups in job shop, production, and maintenance machining environments. The regular length profile fits standard tool holders and collet systems accepting a 7/16-inch shank diameter. The fine-pitch flute configuration is intended for smooth cutting action during roughing passes where surface finish is secondary to removal rate. It is not center-cutting, so plunge entry is not recommended without a pre-drilled entry point or ramping toolpath.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• TiCN coating improves surface hardness and reduces friction during cutting
• 4-flute fine-pitch design optimized for roughing passes and chip clearance
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• 7/16-inch shank diameter with tight tolerance (+0.0001 to -0.0004 inch) for secure holder fit
• Non-center-cutting geometry — requires ramp or pre-drilled entry for plunge moves

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill compatible with standard collet chucks, end mill holders, and tool holders accepting a 7/16-inch straight shank.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before inserting or removing the end mill from the tool holder. Ensure the shank is fully seated and the collet or set screw is torqued to the tool holder manufacturer specification before spindle engagement. Inspect the cutting edges for chips or wear before each use, as carbide tooling can fail without visible warning if run in an unsuitable application.
