Accupro 12182697 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182697 is a solid carbide square end mill designed for precision milling in tight, small-feature applications. Built from micrograin solid carbide, this stub-length tool measures 0.0469 inches (3/64 inch) in cutting diameter with a 0.0938-inch (3/32 inch) length of cut and a 1/8-inch shank diameter. The four-flute, spiral configuration with a 30-degree helix angle provides efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. The right-hand cut and right-hand flute orientation are standard for conventional CNC milling operations. At 1.5 inches overall length, this uncoated end mill is suited for high-speed machining centers and CNC routers where rigidity and dimensional accuracy are critical.

This end mill is intended for use in precision machining environments handling small-feature work, including slots, pockets, profiling, and contour milling on materials such as aluminum, brass, steel, and plastics. The centercutting geometry allows plunge cutting directly into the workpiece, expanding its application range. The stub-length configuration minimizes deflection, making it a practical choice for machinists working with close tolerances on small components in aerospace, medical device, electronics, and general production machining.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance
• 4-flute spiral design with 30-degree helix angle for efficient chip removal
• Centercutting geometry allows direct plunge entry into the workpiece
• Stub-length configuration reduces deflection in small-feature milling
• Right-hand cut and right-hand flute for standard CNC mill orientation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent part accuracy

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in CNC machining centers and manual mills with a 1/8-inch collet or chuck accepting a 0.1250-inch shank diameter (tolerance -0.0001 / -0.0004 inches).

Installation Notes

Installation is performed by qualified machinists or CNC operators. Before installing or changing tooling, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per facility safety procedures. Secure the shank in a properly sized collet or end mill holder, verifying runout is within acceptable limits before beginning a cut. Avoid excessive overhang beyond the collet face to preserve the rigidity advantages of the stub-length design.
