Rubert 333 | Microsurf Roughness Comparator – Hand Filing | Ra 0.4–6.4 µm, Rz 2.5–63 µm, N5–N9
Covering Ra 0.4–6.4 µm and Rz 2.5–63 µm, roughness grades N5–N9 across 5 patches, the Rubert 333 is the Microsurf comparator for hand-filed surfaces. As part of the lightweight 300 series it is designed for office and design use rather than the workshop, and it is packed in a plastic wallet with an instruction card. For workshop use, the heavy-duty Series 100 equivalent is the 133.
