Accupro 12178963 Square End Mill 1/8 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12178963 is a 4-flute solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.125-inch mill diameter and a 0.5-inch length of cut, this tool handles slotting, profiling, and finish milling in ferrous and non-ferrous materials. The nACRo coating provides enhanced hardness and oxidation resistance, making it well suited for high-speed applications and abrasive workpiece materials. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction delivers consistent edge integrity across extended tool life.

This end mill fits standard CNC machining centers and manual mills using a 0.125-inch collet or chuck. It is designed for regular-length applications where reach and deflection are not primary concerns. Typical use cases include small-feature profiling, slot milling, and finishing passes in tool and die work, aerospace component machining, and precision part manufacturing. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole.

Key Features

• nACRo coating for improved wear resistance and performance in hard and abrasive materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design permits direct plunge milling
• Right-hand cut and right-hand spiral flute configuration for standard CNC and manual mill setups
• Micrograin solid carbide construction for precise, consistent edge geometry
• Mill diameter tolerance of +0.000 / -0.002 inches for tight-tolerance work

Compatibility

Designed as a standard replacement or production end mill for machining centers and manual mills using a 0.125-inch collet or tool holder system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Verify collet condition and runout before tightening to the tool holder manufacturer's specification. Inspect the cutting edges under magnification before use to confirm no shipping damage.
