Description
The Klingspor 148971 (PS 33 B) is an elite industrial-grade abrasive sheet engineered for precision finishing in the woodworking, automotive refinishing, and surface coating sectors. Utilizing a high-performance semi-open aluminium oxide grain on a flexible B-weight paper backing, this 400-grit sheet provides an optimal balance between aggressiveness and flexibility. The integrated active-agent stearate coating significantly reduces loading and dust adhesion, ensuring a consistently clean scratch pattern and a significantly extended service life when sanding paints, varnishes, and high-build fillers.
