Unlike traditional abrasive wheels, clean and strip (coral) discs are made of a three-dimensional non-woven web with abrasive grains. Thanks to their open porous structure, they do not clog with grinding debris and maintain their cutting performance throughout their entire service life. The flexibility of the fibers allows the tool to conform to complex contours, grooves, corners, and curved surfaces, while minimal heat generation in the contact zone reduces the risk of damaging the base material, which is especially critical for thin sheet metal and coated surfaces.
A key advantage of clean and strip discs is their ability to remove rust, mill scale, old paint coatings, epoxy resin, adhesives, and other contaminants virtually without affecting the base material. The processing leaves no deep scratches, making the tool ideal for final surface preparation before painting or further treatment.
To ensure the most accurate tool selection for a specific task, Luga Abrasive Plant offers strip discs in four hardness grades, visually color-coded:
- Purple (RIGID / EXTRA COARSE): Designed for the most aggressive work. Effectively removes heavy layers of scale, old coatings, thick rust, and concrete drips. Ideal for metal and other hard surfaces where intensive material removal is required.
 |
 |
- Blue (MEDIUM HARDNESS): Provides the perfect balance between removal performance and delicate processing. Enables the removal of paint coatings, epoxy resins, and rust with minimal risk of damaging the underlying workpiece. Suitable for wood, metal, and plastic.
 |
 |
- Orange (UNIVERSAL): A well-balanced option for most standard tasks. Features universal hardness, making it suitable for stripping various contaminants, grinding stainless steel, and general finishing work. The optimal choice for regular workshop use.
 |
 |
- Black (SOFT / FINE): Engineered for the most delicate processing and curved contours. Provides gentle stripping, preventing damage when working on non-ferrous metals, plastic, and wood. Ideal for fine finishing, blending, and removing minor surface imperfections, especially in auto body repair.

All clean and strip discs mount onto a standard angle grinder just as easily as a conventional abrasive wheel, making them convenient to use without requiring specialized skills. The discs are manufactured in accordance with TU 23.91.11.140-012-00221209-2025 and GOST R 52588-2011 standards, confirming their high quality and reliability.
