Accupro 95168731 Square End Mill 1/2 in 3 Flute Carbide Altin

Product Description

The ACCUPRO 95168731 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built from micrograin carbide and coated with AlTiN for heat and wear resistance, this stub-length tool handles aggressive cuts where tool rigidity matters. It features a 0.5 inch cutting diameter, a 5/8 inch length of cut, and a 60-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. The single-end, three-flute configuration balances chip load capacity with surface finish quality. This tool is typically installed by machinists and CNC operators working in production or job shop settings.

This end mill is suited for milling ferrous and non-ferrous metals, hardened steels, and high-temperature alloys where AlTiN coating provides thermal protection at elevated cutting speeds. The stub length design minimizes deflection, making it effective for slotting, profiling, and face milling operations that require tight tolerances and consistent tool life. The right-hand cutting and right-hand flute direction are standard for conventional CNC machining center spindles.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in high-temperature cutting applications
• 60-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Stub length design minimizes deflection for improved dimensional accuracy
• Center-cutting geometry allows plunge entry into workpiece material
• Mill diameter tolerance of +0.000/-0.002 inches for consistent fitment and cut accuracy

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 1/2 inch shank collets and end mill holders used in CNC machining centers and manual milling machines with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and powered down before changing tooling. Use a calibrated torque wrench and the appropriate collet or end mill holder to seat the 1/2 inch shank securely without over-tightening. Verify runout with a dial indicator after tool installation to confirm concentricity before beginning a cut.
