Robbjack SS-2-013 Square End Mill 0.013 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-013 is a solid carbide square end mill engineered for precision micro-milling applications. With a 0.013-inch cutting diameter and a 0.0195-inch length of cut, this stub-length tool is designed for high-accuracy work in tight geometries where rigidity and minimal deflection are critical. The 1/8-inch straight cylindrical shank and 1.5-inch overall length provide a compact, stable platform. Built from Tuffy-grade solid carbide, it delivers the hardness and wear resistance required when machining demanding materials. Two spiral flutes with a 30-degree helix angle promote efficient chip evacuation at the micro scale. Installed and operated by machinists and CNC tool-and-die professionals.

The SS-2-013 is suited for precision micro-milling operations in CNC machining centers and high-speed spindle applications. Its stub-length geometry minimizes runout and deflection, making it appropriate for engraving, slotting, and fine-feature work in metals, composites, and engineering plastics. The centercutting design allows plunge entry where required. Right-hand cut and right-hand flute configuration match standard CNC spindle rotation without special setup considerations.

Key Features

• 0.013-inch cutting diameter with plus or minus 0.0005-inch mill diameter tolerance for tight dimensional control
• Tuffy-grade solid carbide construction for superior hardness and wear resistance
• 30-degree helix spiral flute geometry promotes efficient chip evacuation in micro-milling cuts
• Centercutting capable - supports direct plunge entry
• Stub-length design maximizes rigidity and reduces deflection at small diameters
• Uncoated finish - compatible with a broad range of cutting fluids and materials without coating compatibility concerns

Compatibility

Designed as an OEM-style solid carbide micro end mill for use in CNC machining centers and high-speed spindle setups requiring a 1/8-inch straight cylindrical shank and 0.013-inch cutting diameter in the ROBBJACK SS-2 series.

Installation Notes

Installation should be performed by qualified machinists following shop safety protocols. Secure the 1/8-inch shank in a collet or toolholder rated for the spindle speed and runout tolerances required by the application. Verify spindle is fully stopped and de-energized before tool changes. At this diameter, tool breakage risk increases significantly with excessive feed rates, improper chip evacuation, or runout beyond tolerance - confirm holder and collet condition before use.
