Accupro 12182154 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The ACCUPRO 12182154 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/32-inch (0.0938 inch) cutting diameter, a 3/16-inch length of cut, and a 1/8-inch shank diameter with a 1-1/2-inch overall length in a stub-length configuration. The three-flute, spiral-flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute direction. Centercutting capability allows plunge entry. The micrograin carbide substrate provides edge retention and rigidity in close-tolerance slotting and profiling operations. This tool is typically installed and operated by machinists and CNC mill operators working in job shop or production environments.

This end mill suits stub-length applications where rigidity is critical and deflection must be minimized. Its 3/32-inch diameter makes it well suited for small-feature milling, narrow slots, and detailed contour work in materials where a compact, stiff tool is required. The uncoated finish is appropriate for use with cutting fluids and in applications where coating compatibility or post-processing considerations matter. The 1/8-inch shank fits standard collets commonly used on CNC machining centers and manual knee mills.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• Three-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Stub-length configuration minimizes deflection in tight-tolerance work
• Uncoated surface compatible with cutting fluid use across a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills equipped with 1/8-inch collets or tool holders accepting a 0.1250-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet. Verify collet size matches the 1/8-inch shank before tightening to the tool holder manufacturer's specified procedure. Inspect the cutting edges for chips or damage before each use, as carbide is brittle and sensitive to improper handling or interrupted cuts without proper parameters.
