Stone fabrication and masonry work move through three stages: cut and shape, grind and smooth, then polish. Soartec supplies pneumatic angle grinders from 3" to 7", air polishers from 2" to 5" and air die grinders for detail work on stone, granite and masonry.
What stone and masonry work demands
-
The right size for each stage: large grinders remove material fast; smaller grinders and polishers handle edges, profiles and finishing.
-
Low-speed polishing: polishing stone works best at controlled speeds, so polisher RPM matters as much as pad size.
-
Dust control: grinding stone, concrete and brick releases crystalline silica dust. In the US, OSHA's silica standard for construction requires employers to limit worker exposure, and applying water substantially reduces dust when cutting these materials.

FAQ
What tool is used to polish granite?
A low-speed air polisher with a hook-and-loop pad, run through progressively finer polishing pads. Soartec polishers run from 2,300 to 4,500 RPM.
What size angle grinder is best for stone?
Use 7" for heavy cutting and stock removal, and 4"–5" for edge shaping and general grinding.
Why use air tools instead of electric for stonework?
Air tools have no electric motor, which suits wet work environments, and they are typically lighter than electric tools of similar output.
