Accupro 12178930 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The ACCUPRO 12178930 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. Built from micrograin carbide and finished with a TiCN coating, it delivers extended tool life and improved wear resistance in demanding cutting environments. The 3-flute, spiral-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 3/32 inch (0.0938 inch) cutting diameter with a 3/8 inch length of cut, this end mill is suited for fine detail work, slotting, and profiling in tight geometries. Licensed machinists and tool-and-die professionals are the primary users.

This end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. The centercutting design allows plunge cutting in addition to peripheral milling, making it versatile for pocketing and contouring operations. The 1/8 inch shank fits standard collets and tool holders in that size class. Its 1-1/2 inch overall length keeps deflection low during deep-reach applications within its rated length-of-cut range.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• TiCN finish for improved wear resistance and reduced friction
• 3-flute spiral-flute design with 30-degree helix for efficient chip removal
• Centercutting geometry enables plunge, slot, and profile milling
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Regular length type keeps rigidity high in small-diameter applications

Compatibility

Designed as a standard small-diameter square end mill for use in CNC machining centers and manual mills accepting a 1/8 inch shank collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or tool holder to the recommended grip depth and torque the retention mechanism per the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the workpiece and the tool.
