Accupro 12178813 Square End Mill 0.125 in 2 Flute Carbide

Product Description

The ACCUPRO 12178813 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 0.125 inch (1/8 inch) mill diameter with a 0.750 inch length of cut and a 2-1/4 inch overall length. The two-flute, spiral geometry runs a 40-degree helix angle with a right-hand cut and right-hand flute direction. The nACRo finish provides enhanced wear resistance and heat reduction during high-speed machining. Micrograin carbide construction supports tight tolerances and extended tool life. This end mill is centercutting, allowing it to plunge directly into workpieces without a pre-drilled entry point. It is sold as a single unit.

This end mill is suited for slotting, profiling, and light contouring operations on CNC machining centers and manual mills. The 0.125 inch shank diameter fits standard collet systems, making it a practical choice for close-tolerance work in mold making, die work, aerospace component machining, and general precision fabrication. The compact diameter makes it well suited for fine detail work and narrow slot applications where larger tools cannot reach. It is typically installed and operated by machinists and CNC programmers working in job shop and production environments.

Key Features

• Solid micrograin carbide construction for rigidity and dimensional stability
• nACRo coating for improved wear resistance and reduced thermal buildup
• 40-degree helix spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a standard 1/8 inch shank square end mill compatible with collet-style toolholders and end mill holders accepting 0.125 inch shank diameters on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully powered down and at rest before changing tooling. Seat the shank fully into the collet or toolholder to the recommended grip depth and torque the collet nut per the toolholder manufacturer specifications. Verify runout with a dial indicator after installation before beginning a cut, particularly given the tight shank diameter tolerances on this tool.
