Accupro 12176937 Square End Mill 3/32 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12176937 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide and finished with an nACRo coating, this tool delivers extended tool life and heat resistance in demanding cutting environments. It features a 3/32 inch (0.0937 inch) mill diameter, a 9/32 inch length of cut, and a 1/8 inch shank diameter with a total overall length of 1-1/2 inches. The 4-flute, 30-degree spiral helix geometry promotes efficient chip evacuation and smooth surface finishes. This end mill is centercutting, allowing plunge entry into workpieces, and is suitable for machinists and tool-and-die professionals running CNC or manual milling equipment.

This end mill is well-suited for fine detail work, slot milling, profiling, and contouring in small-scale or precision machining setups. The extended reach of 5/8 inch makes it practical for deeper pocket milling where clearance is a factor. Its right-hand cut and right-hand flute configuration are compatible with standard CNC machining center spindle rotation. Typical applications include mold and die work, aerospace components, and precision part production where tight tolerances and consistent finish quality are required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• nACRo finish coating for improved heat resistance and extended tool life
• 4-flute spiral design with 30-degree helix angle for efficient chip removal
• Centercutting geometry allows direct plunge entry into material
• Extended reach of 0.625 inches provides clearance for deeper pocket work
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent precision

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using a 1/8 inch collet or tool holder. Right-hand cut and right-hand flute orientation is compatible with conventional spindle rotation on standard milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque tool holder set screws or collet nuts according to the tool holder manufacturer specifications. Verify runout after installation to maintain dimensional accuracy within the tolerance range of this end mill.
