Accupro 2500046 Roughing End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 2500046 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiCN, it delivers hardness and wear resistance in demanding cutting environments. The 1-inch mill diameter pairs with a matching 1-inch shank diameter for rigid tool holding. With a 3.25-inch length of cut and 6-inch overall length, this is a long-series tool suited for deeper reach applications. Right-hand cutting and right-hand flute direction are standard. Centercutting geometry allows plunge entries. This tool is installed and operated by machinists and CNC operators in job shop and production environments.

The 2500046 is suited for roughing passes on ferrous and non-ferrous materials where fast stock removal is the priority. The four-flute configuration balances chip evacuation and rigidity. The TiCN coating adds surface hardness and reduces built-up edge, extending tool life in steels and alloys. The long-series length makes it a practical choice when standard-length tools cannot reach the required depth of cut. It is compatible with standard R8, CAT, BT, and HSK toolholders accepting a 1-inch shank.

Compatibility

Designed as a direct-fit replacement-style roughing end mill for any toolholder accepting a 1-inch straight shank, including standard R8, CAT, BT, and HSK systems. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the spindle before loading or removing the tool. Seat the shank fully in the toolholder collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use and verify runout with a dial indicator after seating.
