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 on stainless , 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.

NEW! We now offer an open-coat aluminium oxide designed for soft woods (2920), a zirconia for working on rubber/leather/plastics (R817), a SiC/cork mix for finer finishing on glass/brass/GRP (RB515/RB555), two long-lasting agglomerate materials for polishing/graining on all metals (JG530/PG730), and a yellow felt for finer finishing and buffing/brightening a surface.

Please note that the usual lead time for made to order belts is approx. 7 working days. To confirm whether something is a stock or made to order item please feel free to ask in our online chat.
