Accupro 313643 Ball End Mill 7/16 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313643 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous metals, hardened steels, and alloy materials. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding cutting applications. The tool features a ZrN (zirconium nitride) coating that reduces friction and extends tool life in high-speed finishing passes. With a 45-degree helix angle and right-hand cutting direction, it promotes efficient chip evacuation and smooth surface finish. This end mill is installed and used by machinists and tooling professionals in CNC machining centers and manual mills.

This end mill suits stub-length applications where rigidity is prioritized over reach. The 7/16-inch diameter and 9/16-inch length of cut make it well suited for contouring, profiling, and finishing passes in mold work, die work, and general precision machining. Its compact stub-length geometry minimizes deflection in tight-tolerance work. The solid carbide construction supports use at elevated spindle speeds typical of modern CNC operations. It is appropriate for both roughing finish passes and final contour work where surface quality is critical.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• ZrN coating reduces friction and improves tool life in high-speed cuts
• 45-degree helix angle promotes efficient chip evacuation
• Right-hand cut and right-hand flute direction for standard CNC spindle use
• Stub-length design minimizes deflection in tight-tolerance applications
• Single-end configuration with spiral flute geometry

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual milling machines accepting a 7/16-inch straight shank end mill.

Installation Notes

Installation is performed by a machinist or tooling technician using an appropriate end mill holder or collet chuck rated for the 7/16-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine builder guidelines for speed and feed parameters appropriate to the workpiece material.
