Accupro 12177085 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177085 is a square-end, single-end carbide end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a solid micrograin carbide construction with an AlTiN coating, which increases surface hardness and heat resistance at the cutting edge. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With four spiral flutes, a 3/8-inch mill diameter, and a 7/8-inch length of cut, this tool delivers consistent performance in slotting, profiling, and peripheral milling. It is installed and used by machinists and toolroom professionals working on CNC machining centers and manual mills.

This end mill is suited for general-purpose milling in job shops, production machining, and maintenance environments. The centercutting geometry allows plunge cuts in addition to standard peripheral and slot milling. The AlTiN finish extends tool life in high-temperature cutting conditions, making it a practical choice for harder steels and alloy materials. The right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling on vertical machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 40-degree helix angle promotes smooth chip flow and reduced cutting force
• Centercutting design allows direct plunge entry into workpiece
• Four spiral flutes for a balance of chip clearance and edge strength
• Right-hand cut, right-hand flute configuration for standard machining center use

Compatibility

Designed as a standard 3/8-inch shank end mill compatible with ER collets, end mill holders, and shrink-fit toolholders sized for 3/8-inch shank tooling on vertical and horizontal CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle and toolholder are clean and free of chips or debris before seating the shank. Torque the collet nut or set screw to the toolholder specification provided by the holder manufacturer. Verify runout at the cutting diameter before beginning a production operation, as excessive runout accelerates edge wear and reduces surface finish quality.
