Accupro 12178778 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12178778 is a 2-flute solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 0.125 inch cutting diameter, a 0.25 inch length of cut, and a 1.5 inch overall length, making it a stub-length tool suited for rigid setups with minimal overhang. The micrograin carbide construction provides wear resistance and edge integrity at elevated cutting speeds. The nACRo finish reduces friction and extends tool life in hardened steels, stainless, and high-temp alloys. Installed by machinists and CNC operators, this end mill fits standard 1/8 inch collets and tool holders.

This end mill is appropriate for slotting, profiling, and plunging operations in ferrous and non-ferrous materials. Its centercutting geometry allows direct plunge entry without pre-drilling. The 40-degree helix angle promotes chip evacuation and reduces cutting forces, making it a practical choice for finishing passes and light to medium roughing in small-feature work. It is a single-end, right-hand cut, right-hand flute tool suited for vertical machining centers and CNC routers running standard spindle rotation.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• nACRo finish for reduced friction and improved performance in hardened and high-temp materials
• 40-degree spiral helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge cutting without a pilot hole
• Right-hand cut and right-hand flute for use with standard CNC spindle rotation
• Stub length type provides added rigidity and reduced deflection

Compatibility

Designed for use in any 1/8 inch collet or tool holder on vertical machining centers, CNC mills, or CNC routers requiring a stub-length square end mill with a 1/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder that matches the 0.125 inch shank diameter and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout after installation before beginning a cutting operation.
