Accupro 2500304 Square End Mill 3/4 in 5 Flute Carbide Ticn

Product Description

The ACCUPRO 2500304 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built from micrograin carbide and coated with titanium carbonitride (TiCN), it delivers strong wear resistance and extended tool life in ferrous and non-ferrous materials. The 5-flute geometry with a 45-degree right-hand spiral helix provides aggressive chip evacuation and a smooth surface finish. At 3.25 inches length of cut and 6 inches overall length, this is a long-reach tool suited to deep-pocket and deep-slot applications. It is center-cutting and single-end. Installation and operation are performed by machinists and CNC tooling technicians.

This end mill is used in CNC machining centers and manual milling machines where deep-reach cutting is required. The 3/4-inch diameter and 3/4-inch shank allow it to run in standard ER or end mill holders without adaptation. The long flute length of 3.25 inches makes it appropriate for slotting, profiling, and pocketing operations where standard-length tools cannot reach the full depth. The TiCN coating improves performance in harder steels, cast iron, and stainless materials. Right-hand cutting direction is standard for conventional spindle setups.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating provides enhanced wear resistance and heat tolerance
• 5-flute design increases feed rate capability and finish quality
• 45-degree helix angle promotes smooth chip flow and reduced chatter
• Center-cutting geometry allows direct plunge entry
• Long-length series with 3.25 inches length of cut for deep-reach applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3/4-inch straight shank in ER collet chucks, end mill holders, or Weldon-style holders.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank to the recommended engagement depth in the holder and torque the set screw or collet nut to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, particularly given the long overhang of this tool, as excessive runout will accelerate edge wear.
