Selection
What materials are suitable for
Choose the right tool depending on the material being processed
Grinding of welds
Coarse grains P24-P36 for quick removal of weld excess and surface leveling.
Rough metal removal
P24-P40 grit for aggressive removal of a significant layer of metal. High performance on steel and cast iron.
Rust and scale removal
Grit size P36-P60 for effective cleaning of metal surfaces from rust, scale and old coatings.
Preparation for painting
P60-P80 to create optimal roughness before applying primer and paint.
Finishing sanding
P100-P120 grit for fine grinding and surface preparation for polishing.
Stainless steel
Zirconia fiber wheels are ideal for INOX due to their cool cutting and lack of overheating.

FAQ
Frequently asked questions
Answers to the most common questions about fiber discs
What is a fiber disc and how does it differ from a flap disc?
A fiber wheel is a grinding wheel with a vulcanized fiber backing coated with abrasive grain. Unlike a flap wheel (which consists of flaps of sandpaper), a fiber wheel has a continuous abrasive layer. It provides more aggressive material removal and longer service life in heavy-duty applications.
Do I need a backing pad for a fiber wheel?
Yes, the fiber wheel must be mounted on a special support (supporting) disc. It ensures proper contact with the surface and prevents premature wear. There are two types in our catalog: smooth flexible (BPFD125F) and ribbed hard (BPFD125H). Flexible is suitable for contoured surfaces, hard - for flat ones.
What grit should I choose for welds?
For rough removal of welds, P24-P36 is recommended. For cleaning and leveling, P40-P60. For finishing after welding, P80-P120. Start with coarser grit and work your way down to finer grit for a high-quality surface.
What is the advantage of zirconia abrasive over aluminum oxide?
Zirconia corundum (Zirconia) has the property of self-sharpening - during operation, the grain is renewed, maintaining its cutting ability. This provides up to 3 times longer service life and stable performance. Zirconia is especially effective on stainless steel and hard alloys.
At what speed should I work with a 125 mm fiber disc?
The maximum speed for a 125 mm fiber disc is 12,200 rpm. It is recommended to work at a speed of 8,000-12,000 rpm. Never exceed the maximum speed indicated on the disc. Use a variable speed angle grinder for optimal results.
Can I use a fiber wheel without water (dry processing)?
Yes, NovoAbrasive fiber wheels are designed for dry processing. The vulcanized fiber base is resistant to heat. However, when working with stainless steel, it is recommended to avoid overheating the workpiece by working with moderate pressure and periodic pauses.
How to properly store fiber discs?
Fiber discs should be stored in a dry room with a relative humidity of no more than 65%. Avoid direct sunlight and sudden changes in temperature. Store horizontally on a flat surface. When stored properly, the shelf life is 3 years from the date of manufacture.
What materials are fiber discs suitable for?
Aluminum oxide fiber wheels are suitable for carbon steel, cast iron, non-ferrous metals and wood. Zirconia wheels are optimal for stainless steel, alloy steels and titanium. Do not use fiber wheels for stone, concrete and other mineral materials.
