DIAMACH 90 x 55mm 30mm Bullnose Hand Polishing Block #50 is a diamond hand polishing block designed for manual polishing, shaping and finishing of stone surfaces. Featuring a 30mm bullnose profile, the block is designed to help polish and refine rounded stone edges and profiles by hand.
The compact 90 x 55mm block provides a convenient format for controlled hand polishing, particularly on edges, curves and detailed areas that can be difficult to reach with larger machine-mounted polishing tools. The #50 grit provides a coarse diamond polishing stage for initial surface refinement before progressing to finer grits.
Ideal for stone fabricators, benchtop installers, tradespeople and restoration applications, the DIAMACH hand polishing block provides a practical solution for detail work and edge finishing.
