Accupro 12182332 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12182332 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 1/16 inch cutting diameter, a 3/16 inch length of cut, and a 1/8 inch shank diameter with an overall length of 1.5 inches. The 4-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting performance. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and edge retention in demanding cutting conditions. Centercutting capability allows plunge milling as well as peripheral cuts.

This end mill is suited for slot milling, profiling, and finishing passes in small-feature work where tight tolerances are required. Its compact 1/16 inch diameter makes it well-matched to fine detail machining, engraving setups, and narrow slot operations on CNC machining centers and manual mills. The regular-length profile fits standard toolholders with 1/8 inch bore capacity. Machinists, toolmakers, and CNC operators working in job shops, aerospace component work, and precision manufacturing will find this tool appropriate for finishing cuts in steel, stainless, cast iron, and harder non-ferrous alloys.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention at small diameters
• TiCN coating for improved wear resistance and reduced tool-to-workpiece friction
• 4-flute, 30-degree right-hand spiral for efficient chip flow and surface finish quality
• Centercutting design allows plunge entry as well as side and slot milling
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in tight-tolerance work
• Shank diameter tolerance of -0.0001 / -0.0004 inches for secure, repeatable toolholder seating

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills accepting a 1/8 inch shank collet or toolholder. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully de-energized and locked out before changing tooling. Seat the 1/8 inch shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Inspect the cutting edges for chips or coating damage before use, especially at this diameter where edge integrity is critical. Follow your machine tool builder guidelines for spindle speed and feed rate selection at 1/16 inch diameter to avoid deflection or breakage.
