Accupro 313469 Square End Mill 3/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313469 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/4 inch mill diameter with a 2-1/2 inch length of cut and a 5 inch overall length, making it well-suited for slotting, profiling, and peripheral milling operations. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A zirconium nitride (ZrN) coating adds surface hardness and heat resistance, extending tool life in moderate-to-high-speed applications. Micrograin carbide construction provides the substrate rigidity needed for consistent dimensional results across production runs.

This end mill is used in CNC machining centers and manual knee mills across job shops, toolrooms, and production environments. The centercutting geometry allows plunge cuts in addition to standard peripheral and slot milling. Right-hand cut with right-hand spiral flute direction is the conventional configuration for most vertical and horizontal spindle setups. With a 3/4 inch shank diameter matching the cutter diameter, it seats directly in standard ER, CAT, BT, and similar collet or arbor toolholding systems without a reducing adapter.

Key Features

• Solid micrograin carbide construction for rigidity and dimensional stability
• ZrN coating for improved wear resistance and tool life at elevated cutting speeds
• 45-degree helix angle promotes smooth chip flow and reduced cutting pressure
• Centercutting design permits plunge milling in addition to peripheral and slot cuts
• Right-hand cut, right-hand spiral flute — standard orientation for most CNC and manual setups
• Mill diameter tolerance of +0.000 / -0.002 inches; shank diameter tolerance of +0.0001 / -0.0004 inches

Compatibility

Designed as a direct-fit replacement for standard 3/4 inch shank square end mill applications in CNC machining centers and manual mills using ER collets, CAT, BT, or equivalent toolholding systems.

Installation Notes

Installation is performed by machinists and CNC tooling technicians. Power down and lock out the spindle drive before changing tooling. Seat the shank fully into the collet or arbor and torque the retention hardware to the toolholder manufacturer's specification. Verify runout with a dial indicator before engaging the cut, particularly in finish-milling or close-tolerance applications.
