Accupro 2500448 Square End Mill 5mm 2 Flute Carbide Zrn

Product Description

The ACCUPRO 2500448 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 5 mm (0.1970 inch) cutting diameter and a 16 mm length of cut, this tool delivers controlled material removal in a compact, rigid package. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces, while the ZrN (zirconium nitride) coating improves wear resistance and surface finish on a wide range of workpiece materials. The micrograin carbide substrate supports higher feed rates and finer finishes compared to standard carbide grades. This end mill is intended for use by machinists and CNC operators in production and job-shop environments.

This tool is suited for slot milling, peripheral milling, and profiling operations in ferrous and non-ferrous metals, alloys, and plastics. The 6 mm shank diameter fits standard ER collet chucks and end mill holders commonly found on CNC machining centers and manual knee mills. The regular-length configuration makes it appropriate for general-purpose applications where extended reach is not required. The center-cutting geometry allows direct plunge entry when needed.

Key Features

• 5 mm cutting diameter with a tight mill diameter tolerance of +0.000 / -0.002 inches
• ZrN coating for enhanced wear resistance and extended tool life
• 45-degree right-hand spiral helix for aggressive chip evacuation
• Micrograin solid carbide substrate for rigidity and edge retention
• Center-cutting capable - supports plunge milling
• 2-flute geometry for improved chip clearance in slotting operations

Compatibility

Designed for use in standard ER collet chucks, shrink-fit holders, and end mill holders accepting a 6 mm shank diameter. Suitable for CNC machining centers and manual mills configured for metric tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the holder. Verify collet or holder runout with a dial indicator before production use, as excessive runout accelerates edge wear and degrades surface finish. Follow machine tool manufacturer guidelines for tool projection length and clamping torque on the holder.
