Accupro 313949 Square End Mill 1/2 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313949 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 1/2 inch cutting diameter and a 5/8 inch length of cut, with a 4 inch overall length and a 1/2 inch shank diameter. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating improves surface hardness and wear resistance, extending tool life in demanding cuts. This end mill is center-cutting and runs in a right-hand cutting and right-hand flute direction. It is used by machinists and toolroom professionals working on CNC mills and manual milling machines.

This end mill suits general-purpose slot milling, profiling, and peripheral milling in ferrous and non-ferrous materials. The micrograin carbide substrate supports tight tolerances and consistent performance across production and job-shop environments. With a 2-flute configuration, it handles applications where chip clearance is a priority, such as milling softer metals or semi-finish passes. It is a single-end tool sold individually.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating for improved tool life and surface finish
• 45-degree helix angle promotes efficient chip evacuation
• Center-cutting design allows plunge entry
• Right-hand cut and right-hand spiral flutes
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fitment

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling machine spindles accepting a 1/2 inch straight shank with standard ER or side-lock toolholders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and spindle locked. Confirm toolholder runout is within acceptable limits before securing the shank. Verify shank seating depth meets the toolholder manufacturers minimum engagement requirement. Always use appropriate cutting parameters for the workpiece material and machine rigidity.
