Accupro 12182483 Square End Mill 9/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182483 is a 4-flute, solid carbide square end mill designed for precision milling in ferrous and hard materials. It features an AlTiN (aluminum titanium nitride) coating that extends tool life in high-heat cutting environments. The micrograin carbide substrate provides edge strength and wear resistance. With a 40-degree helix angle and spiral flute geometry, this end mill produces efficient chip evacuation and smooth surface finishes. The centercutting design allows plunge milling in addition to peripheral cuts. It is a right-hand cut, right-hand flute tool in a regular-length configuration. Licensed machinists and CNC operators install this tool in milling machines and machining centers for slotting, profiling, and pocketing operations.

This end mill is suited for use in vertical and horizontal milling machines, VMCs, and HMCs. The 9/32 inch diameter and 3/4 inch length of cut make it appropriate for finishing passes and tight-tolerance slots in ferrous metals, stainless steel, and hard alloys where AlTiN coating performance is required. The 5/16 inch shank fits standard collets and end mill holders used in production and job shop environments. It ships as a single unit and is a direct catalog item for machine shops requiring close-tolerance tooling.

Key Features

• AlTiN finish for high-heat resistance and extended tool life in ferrous and hard materials
• Micrograin solid carbide substrate for superior edge retention and rigidity
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting design enables plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance applications

Compatibility

Designed as a direct-fit replacement for standard 5/16 inch shank end mill holders, ER collets, and milling chucks used in CNC machining centers and manual milling machines requiring a 9/32 inch diameter square end mill.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before inserting or removing the tool. Use a calibrated torque wrench and the appropriate collet or end mill holder to secure the shank to the specified holding system requirements. Verify runout with a dial indicator after installation to confirm the tool seats within tolerance before beginning a cut.
