Accupro 313293 Square End Mill 1/2 in 2 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 313293 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.5 inch mill diameter, a 45-degree helix angle, and a ZrN (zirconium nitride) finish, this end mill delivers clean cuts with reduced friction and extended tool life. The micrograin carbide substrate supports high-speed cutting in harder workpiece materials. It features a spiral flute geometry with right-hand cut and right-hand flute direction, making it suitable for conventional CNC milling setups. Machinists and toolroom operators use this tool in production shops and job shops handling ferrous and non-ferrous materials.

This end mill fits standard CNC machining centers and manual mills accepting a 0.5 inch shank. The 0.75 inch length of cut and 3 inch overall length make it well suited for general-purpose slotting, profiling, and contouring at moderate depths. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole, adding flexibility in programming. It is a single-end tool intended for production use where solid carbide rigidity is required over high-speed steel alternatives.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• ZrN coating reduces friction and improves surface finish in non-ferrous and ferrous cuts
• 45-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand spiral flute for standard CNC spindle compatibility
• Tight mill diameter tolerance of plus 0.000 / minus 0.002 inches supports dimensional accuracy

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual milling machines with a 0.5 inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator before beginning production cuts to confirm proper seating and avoid premature tool wear.
