Accupro 313094 Square End Mill 9/32 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313094 is a solid carbide square end mill engineered for precision milling in demanding metalworking and machining applications. With a 9/32 inch (0.2813 inch) cutting diameter, 2 flutes, and a 45-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action in a variety of materials. The ZrN (zirconium nitride) coating provides enhanced surface hardness and heat resistance, extending tool life during high-speed operations. Micrograin carbide construction contributes to edge retention and dimensional stability. This is a single-end, right-hand cutting tool with a regular length designation, suited for use in CNC machining centers and manual mills operated by machinists and toolroom professionals.

This end mill is appropriate for milling slots, profiles, and pockets in ferrous and non-ferrous metals, plastics, and composite materials. The centercutting design allows plunge entry into the workpiece. The 5/16 inch shank diameter fits standard collet chucks and end mill holders common in both vertical machining centers and manual knee mills. The 13/16 inch length of cut and 2-1/2 inch overall length make it well-suited for shallow-to-moderate depth operations in production and toolroom environments.

Key Features

• 9/32 inch (0.2813 inch) cutting diameter with mill diameter tolerance of +0.000/-0.002 inches
• ZrN (zirconium nitride) coating for improved wear resistance and heat dissipation
• 45-degree right-hand spiral helix for efficient chip evacuation
• Micrograin solid carbide substrate for edge retention in demanding cuts
• Centercutting geometry allows direct plunge entry
• Single-end design with 2 flutes for general milling operations

Compatibility

Designed as an OEM-style replacement or standard tooling selection for use in collet chucks and end mill holders accepting a 5/16 inch shank diameter, common in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists following standard tooling change procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism per the machine or toolholder specification. Verify runout with a dial indicator before beginning cuts, particularly for tight-tolerance work.
