Frequently Asked Questions
What is this round wire brush used for?
It is used with grinders for cleaning and finishing metal surfaces for sanding, polishing, or finishing operations on the material indicated in the model.
The choice of model depends on dimensions (e.g., 150x20x12.7 mm or 200x25x32 mm) and bore (Ø 12.7 or 32 mm) and the type of application (roughing, intermediate sanding, or finishing).
Which grit should I choose?
K36-K60 for aggressive roughing and paint removal, K80-K120 for intermediate sanding, K150-K240 for pre-painting finishing, K320+ for mirror-finish 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. Use the correct consumable to optimize durability and work quality.
For stainless steel, use grinding wheels/abrasives with appropriate binders to avoid overheating and deformation. For aluminum, prefer abrasives with reduced loading.
How many pieces are in the package?
The number of pieces is indicated in the model (e.g., "4 pieces", "5 pieces", "6 pieces"). Multiple packages allow managing replacement breaks 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 should abrasives be 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 sanding pads and paper-backed abrasive belts. Recommended temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated warehouse.
