Accupro 95168590 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 95168590 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 1/8 inch cutting diameter, 1/2 inch length of cut, and a 60-degree helix angle, this tool delivers aggressive chip evacuation and excellent surface finish in tough materials. The AlTiN coating provides high heat resistance and extended tool life, making this end mill well suited for ferrous metals, hardened steels, stainless, and high-temperature alloys. It is a single-end, right-hand cutting tool with right-hand flute direction and a micrograin carbide substrate for added toughness and wear resistance.

This end mill is used in CNC machining centers, vertical mills, and manual knee mills for slotting, profiling, and peripheral milling operations. The 1/8 inch shank diameter matches standard collet sizes commonly found in smaller spindles and high-speed machining setups. Its regular length classification makes it appropriate for standard-depth cuts where rigidity and precision are priorities. Machinists in tool-and-die, aerospace component, and precision parts shops will find this tool a reliable choice for fine-feature work.

Key Features

• 1/8 inch cutting diameter with a tight mill diameter tolerance of +0.000/-0.002 inches for precise fitment
• 60-degree helix angle promotes fast chip evacuation and reduced cutting forces
• AlTiN coating increases heat resistance and extends tool life in ferrous and high-temp alloys
• 3-flute geometry balances chip clearance and rigidity for slotting and profiling
• Centercutting design allows plunge milling capability
• Micrograin solid carbide substrate provides superior wear resistance and edge retention

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8 inch collet or tool-holding systems. Compatible with standard ER and precision collet chucks sized for 1/8 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank fully within the collet or tool holder to the recommended insertion depth and torque the collet nut according to the tool-holder manufacturer's specification. Inspect the cutting edges and coating before use and discard if chipping or wear is evident.
