Accupro 2500256 Roughing End Mill 1/2 in 5 Flute Carbide

Product Description

The ACCUPRO 2500256 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and finished with a TiCN coating, it delivers the wear resistance and edge retention needed for demanding cutting applications. The 1/2 inch diameter tool features 5 fine-pitch flutes with right-hand cutting and right-hand flute direction. It carries a 1.25 inch length of cut and a 3 inch overall length. This is a regular-length tool intended for professional machinists and CNC operators working with ferrous and non-ferrous materials where high-efficiency rough profiling is required.

This end mill is suited for roughing passes in vertical machining centers, knee mills, and CNC milling operations across job shops, production facilities, and tool rooms. The fine-pitch flute geometry makes it particularly effective in harder materials where a coarser pitch could cause chatter or premature wear. The TiCN coating adds lubricity and surface hardness, extending tool life in abrasive cutting conditions. The 1/2 inch shank diameter is a standard size compatible with ER collet chucks, end mill holders, and shrink-fit holders commonly used in the trade.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• TiCN coating extends tool life in abrasive and harder material applications
• 5 fine-pitch flutes for improved chip evacuation during roughing passes
• Right-hand cutting and right-hand flute direction for standard spindle operation
• Non-centercutting design — suitable for peripheral and side milling, not plunge entry
• Shank diameter tolerance of +0.0001 to -0.0004 inches for precise holder fit

Compatibility

Designed as a standard 1/2 inch shank roughing end mill compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems that accept 1/2 inch shank tooling.

Installation Notes

Installation should be performed by qualified machinists following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully in the holder to the recommended engagement depth and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before engaging a cut, as excessive runout accelerates edge wear on carbide tooling.
