335 Zirconia paper Velour discs are designed for the wood sanding and grinding applications.
The robust F-Weight paper combined with the high dense Velour are extremely suitable for high pressure sanding on floor and any other hard wood surfaces.
Due to the Zirconium Alumina grains properties, stock removal rate is accelerated while durability is prolonged compared to the conventional abrasives.
