Robbjack SS-2-014 Square End Mill 0.014 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-014 is a solid carbide square end mill designed for precision micro-machining applications. With a 0.014-inch cutting diameter and a 0.021-inch length of cut, this tool is built for fine-detail work in tight geometries where accuracy is critical. The 30-degree helix spiral flute promotes efficient chip evacuation and reduces cutting forces at small diameters. Featuring two flutes and a right-hand cut with right-hand flute direction, it is center-cutting capable, allowing plunge entry in addition to peripheral and slot milling. The 1/8-inch shank and 1-1/2-inch overall length provide rigidity in standard collet toolholding systems. Machinists and CNC operators working in precision shops install this tool for micro-scale work in metals, plastics, and composites.

The SS-2-014 belongs to RobbJack's SS-2 stub-length series, optimized for high-precision applications requiring minimal runout and tight diameter tolerances. Its stub length classification reduces deflection, making it well-suited for shallow-pocket milling, engraving, and fine-feature contouring in CNC machining centers. The uncoated solid carbide construction suits applications where coating thickness could affect dimensional accuracy at this scale. This tool is appropriate for production and prototype environments where small-diameter, tight-tolerance work is routine.

Key Features

• 0.014-inch cutting diameter with a mill diameter tolerance of plus 0.0005 / minus 0.0005 inches for precise dimensional control
• Solid carbide construction for rigidity and wear resistance at micro diameters
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• 30-degree helix angle promotes smooth chip flow and reduced cutting pressure
• Stub length classification minimizes deflection in shallow-feature applications
• Uncoated finish preserves dimensional accuracy where coating thickness is a concern

Compatibility

Designed as an OEM-style replacement or direct application tool within the RobbJack SS-2 series for CNC machining centers using 1/8-inch collet or toolholder systems requiring a stub-length square end mill at 0.014-inch diameter.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Secure the 1/8-inch shank in a properly sized collet or shrink-fit holder and verify runout before production use, as runout at this diameter scale can directly affect tool life and part accuracy. Never exceed the recommended depth of cut for the 0.021-inch length of cut. Power down and lock out the spindle before changing or inspecting the tool.
