Accupro 2500031 Roughing End Mill 3/4 in 4 Flute Carbide

Product Description

The ACCUPRO 2500031 is a single-end roughing end mill designed for aggressive material removal in CNC milling and manual mill applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting conditions in ferrous and hardened materials. The 3/4-inch diameter tool features 4 flutes with a fine pitch and right-hand cutting and flute direction. At 2.25 inches length of cut and 5 inches overall length, this long-series end mill reaches deeper pockets and shoulders without requiring extended-reach tooling. It is centercutting, allowing plunge entry where needed.

This end mill is suited for production and job-shop environments running steel, stainless, cast iron, and similar materials on vertical or horizontal machining centers. The AlTiN coating supports dry or minimal-coolant cutting, making it a practical choice in shops managing coolant costs or running high-speed spindle operations. The long-series geometry provides clearance in deep-pocket profiling and roughing passes where standard-length tools cannot reach.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• AlTiN coating for thermal resistance during dry or high-speed cutting
• 4-flute fine-pitch design for aggressive roughing with controlled chip load
• Centercutting geometry allows direct plunge entry
• Long-series length of cut (2.25 inches) for deep-pocket access
• Right-hand cut and flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills accepting a 3/4-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a collet or end mill holder rated for 3/4-inch tooling, verifying runout before operation. Power down and lock out the spindle before inserting or removing any end mill. Do not exceed the machine tool and holder rated speed and torque limits for this shank diameter.
