Kovax Toleblock QM curved sand is a unique solution for concave and convex surfaces. Specially developed for those areas that are not flat and difficult to reach with a rectangular block. This ensures an evenly sanded surface with a excellent end result. Tolecut reduces polishing time. Conventional sanding systems for imperfection - removal often consist of 1 to 2 sanding steps. Consequently, the emphasis is on polishing. After all, in only 1 or 2 sanding steps not all sanding scratches will be removed completely, which means extra polishing time is required to entirely remove these final sanding scratches as well.
