Accupro 12178960 Square End Mill 5/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12178960 is a 4-flute solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a micrograin carbide substrate and an nACRo coating, which provides high hardness and heat resistance suited for dry or near-dry cutting conditions. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.0781 inches in diameter with a 0.25-inch length of cut, this tool is built for fine-detail work in tight pockets and small-profile slots. It is installed and operated by machinists and tooling technicians on CNC machining centers and manual mills.

This end mill is designed for small-scale slotting, profiling, and pocketing operations where a fine cutting diameter is required. The centercutting geometry allows for plunge entry without pre-drilling. Right-hand cut and right-hand flute configuration is standard for conventional spindle rotation. The 1/8-inch shank diameter fits common collet systems used in high-speed spindles and standard milling setups. The 1.5-inch overall length keeps the tool compact to minimize deflection at small diameters.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• nACRo coating for elevated heat resistance and extended tool life in demanding cuts
• 30-degree helix angle for efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand spiral flute for standard CNC spindle use
• Tight diameter tolerance of +0.000 / -0.002 inches for precise fit and finish

Compatibility

Designed as a direct-fit tooling solution for 1/8-inch collet systems on CNC machining centers and manual milling machines requiring a 5/64-inch cutting diameter end mill.

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. Secure the shank in a properly sized collet or end mill holder and torque to the machine manufacturer's specified clamping requirements. Inspect the cutting edges for damage before each use, and do not exceed the tool's rated depth-of-cut range of 0.200 to 0.300 inches.
