RobbJack’s SS and SR-series miniature end mills

Miniature tool edge geometries may not be visible to the naked eye, but they’re critical for machining quality and consistency.

RobbJack offers SS and SR-series diameters in every increment of 0.001".

• Cutting diameters starting at 0.005”
• Tolerances in microns (0.000039”), smaller than a human hair
• Hand-select diameters to nearest 0.0002”
• Primary relief angles maximize quality machining performance
• CVD diamond coating for certain applications
