KLINGSPOR velcro-backed sanding discs 150 mm grain 400 hole shape GLS3 147125

PS 33 BK bonded discs, 150 mm grain 400 hole shape GLS3. Advantages: Increased sanding and removal performance thanks to special, heat-tempered aluminum oxide abrasive grain - Reduced clogging thanks to abrasive active ingredients in the top coat and semi-open grain scattering - High flexibility combined with good stability and tear resistance thanks to latex-impregnated paper backing. Klingspor achieves the high removal rate and long service life of the abrasive paper type PS 33 BK by using hard, tough corundum abrasive grain in a semi-open coating. This is especially important when sanding varnish and paint, as it generates a lot of sanding dust. This dust can escape easily with a semi-open coating and the abrasive is less likely to clog. Klingspor offers sanding discs and sanding strips in medium and fine grit sizes. The sanding discs for random orbital sanders are available in various sizes and perforations. The sanding strips for hook and loop backed hand blocks and orbital sanders are also available in various sizes and with or without perforations.
