Accupro 12181231 Square End Mill 0.0591 in 2 Flute Carbide

Product Description

The ACCUPRO 12181231 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.0591 inch (1.50 mm) mill diameter and a 0.1969 inch (5.00 mm) length of cut, this miniature end mill is built for fine detail work and tight-tolerance applications. The TiCN (titanium carbonitride) coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials alike. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the rigidity and edge retention needed for small-diameter tooling where deflection control is critical.

This end mill is suited for CNC machining centers and manual mills handling small-feature work in tool and die, mold making, electronics component machining, and precision part production. The centercutting geometry allows plunge entry, giving machinists flexibility to feed directly into the workpiece. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on most CNC platforms. It fits applications requiring a regular-length tool in a 3.00 mm shank diameter, compatible with standard collet systems in that size range.

Key Features

• 0.0591 inch (1.50 mm) mill diameter for fine-detail and small-feature machining
• TiCN finish for improved wear resistance and extended tool life
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 30-degree helix angle with spiral flute for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute — standard orientation for most CNC setups

Compatibility

Designed for use with collet systems and tool holders accepting a 3.00 mm shank diameter. Suitable for CNC machining centers and manual mills running standard right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Ensure the collet and holder are clean and within tolerance before seating the shank to prevent runout. At diameters under 0.0625 inch, carbide end mills are brittle — avoid excessive overhang and confirm runout with a dial indicator before full-speed operation. Power down and de-energize the spindle completely before tool changes.
