Accupro 12182522 Square End Mill 11/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182522 is a solid carbide square end mill designed for precision milling operations across a range of metalworking applications. With a 11/32 inch (0.3438 inch) mill diameter, a 7/8 inch length of cut, and a 3/8 inch shank diameter, this end mill delivers consistent, accurate cuts in demanding shop environments. The AlTiN coating provides elevated heat and wear resistance, extending tool life in high-speed and dry machining conditions. A 40-degree helix angle combined with a spiral, right-hand flute geometry promotes efficient chip evacuation and smooth cutting action. This tool is single-end and centercutting, supporting both peripheral and plunge operations.

This end mill is suited for milling ferrous and non-ferrous metals, hardened steels, and alloy materials in CNC machining centers and manual mills. The micrograin carbide substrate offers the rigidity and edge retention required for finishing passes and contour milling in production and job shop settings. It is installed and used by machinists, tool-and-die makers, and CNC operators working in precision machining environments.

Key Features

• Solid micrograin carbide construction for superior rigidity and edge retention
• AlTiN coating for enhanced heat resistance and extended tool life in high-speed machining
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting design allows plunge milling and full-slot entry
• Right-hand cut, right-hand spiral flute geometry for conventional CNC spindle compatibility
• Regular length type with 2-1/2 inch overall length for standard reach applications

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual milling machines with a 3/8 inch collet or tool holder.

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. Seat the 3/8 inch shank fully and evenly in the collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator after mounting to confirm proper seating before beginning a cut.
