Abrasive Belt Calculator – Build Your Own Belts

For expert advice on abrasive belts to suit your particular application please call us on 01273 463677.

Use our belt calculators to build your own abrasive belts – please enter your desired material, belt width, length & grade/grit size below, and select ‘Get Prices’. You can also use the filter (optional) to find materials recommended for the specific substrates/surfaces which you are working on. Available materials include aluminium oxide (stiff X-weight or flexible J-Flex), zirconia (with topsize for cooler grinding, or without), ceramic (premium material – with topsize for cooler grinding or without), silicon carbide (perfect for glass!), SCM/non-woven and 3M Trizact, both for polishing.
