Accupro 313225 Square End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313225 is a solid carbide square end mill designed for precision milling in demanding machining environments. Built from micrograin carbide and coated with zirconium nitride (ZrN), this tool delivers extended wear resistance and reduced friction at the cutting edge. The 3/8-inch diameter, 2-flute configuration and 45-degree helix angle promote efficient chip evacuation and smooth cutting action. With a 2-1/2-inch length of cut and a 6-inch overall length, this is an extra-long reach end mill suited for deep-pocket and hard-to-reach workpiece features. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is suited for milling operations requiring extended reach, including deep slots, pockets, and profiling cuts where standard-length tools cannot reach the workpiece. The right-hand cutting direction and right-hand spiral flutes are standard for conventional CNC machining centers and manual mills. The centercutting geometry allows plunge entry into the material. Typical applications include ferrous and non-ferrous metalworking, mold work, and die machining where tight tolerances and surface finish matter.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in metal cutting
• ZrN (zirconium nitride) coating reduces friction and extends tool life in abrasive materials
• 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Extra-long 6-inch overall length with 2-1/2-inch length of cut for deep-reach applications
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style cutting tool replacement or direct-use end mill for CNC machining centers and manual milling machines accepting a 3/8-inch straight shank tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the tool holder. Verify tool holder collet size matches the 3/8-inch shank diameter before clamping. Follow shop-standard runout inspection procedures after tool installation to confirm concentricity before cutting.
