Frequently asked questions
What is this polishing wheel set used for?
It is used with bench grinders and flexible wheels for sanding, polishing, or finishing operations on the specific material indicated in the model.
The choice of model depends on the wheel diameter, bore, and polishing material (stainless steel, aluminum, wood, plastic), and the type of application. Compatible with bench grinders with a wheel bore of Ø 16 or Ø 20 mm accordingly.
Which grit should I choose?
K36-K60 for aggressive roughing, K80-K120 for intermediate sanding, K150-K240 for pre-painting finishing, K320+ for mirror-like surfaces.
The most common mistake is skipping intermediate grits: going from K60 to K240 leaves deep marks that cannot be removed. Always proceed in consecutive steps (e.g., K80 → K120 → K180).
What materials is it compatible with?
The model indicates the specific material (stainless steel, aluminum, wood, plastic). Using the correct abrasive optimizes durability and working quality.
On stainless steel, use abrasives with a suitable binder to avoid heating and deformation. On aluminum, prefer abrasives with reduced loading. On wood, standard corundum is the standard choice.
How many pieces does the package contain?
This package contains 4 pieces. Multiple packages allow you to manage replacements without machine downtime.
For intensive use, it is advisable to keep at least 2-3 packages of the most used grits in stock, so as not to interrupt production when a belt/sleeve runs out.
How are abrasives stored?
Store in a dry place, away from humidity that can alter the binder. Keep them in their original packaging until use to preserve grit and adhesive.
Humidity particularly damages self-adhesive pads and paper-backed abrasive belts. Ideal temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated warehouse.
