Selection guidance
Choose coarser grades for faster correction and finer grades for progressive refinement. Confirm the selected grade, box quantity and compatibility with your backing pad before ordering.
Select diameter, grit and backing as a system
Match the 150mm no-hole disc to a compatible hook-and-loop backing pad. Start with the least aggressive grit that will remove the defect, then work through progressively finer grades before compounding and polishing.
