Accupro 315013 Square End Mill 3/4 in 3 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 315013 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.75 inch mill diameter, a 2.25 inch length of cut, and a 5 inch overall length, this tool is built for full-slot and peripheral milling in a wide range of workpiece materials. The 37-degree helix angle promotes efficient chip evacuation, while the ZrN (zirconium nitride) coating increases surface hardness and reduces friction at the cutting edge. Three spiral flutes provide a balance between chip clearance and cutting stability. This end mill is centercutting, allowing plunge entry directly into the workpiece. It is suited for use in CNC machining centers and manual mills operated by machinists and toolroom professionals.

This end mill is appropriate for milling ferrous and non-ferrous metals in both production and toolroom settings. The right-hand cut and right-hand flute configuration is standard for conventional vertical and horizontal machining center spindles. The micrograin carbide grade supports higher surface footage and longer tool life compared to standard carbide grades, making this a practical choice for finishing passes and moderate material removal rates in steel, stainless, and similar alloys.

Key Features

• 0.75 inch mill diameter with a mill diameter tolerance of +0.000 / -0.005 inches
• ZrN coating for improved wear resistance and reduced built-up edge
• 37-degree helix angle for efficient chip flow in spiral flute configuration
• Centercutting design allows direct plunge milling into the workpiece
• Micrograin solid carbide construction supports higher cutting speeds and extended tool life
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindles

Compatibility

Designed as a standard-shank solid carbide square end mill with a 0.75 inch shank diameter, suitable for use in ER, side-lock, and shrink-fit toolholders that accept 3/4 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully within the toolholder to the minimum insertion depth recommended for the holder type, and verify runout with a dial indicator before production cuts. Do not exceed the toolholder or machine spindle rated RPM for the selected cutting parameters.
