KLINGSPOR PS19EK 225mm P36 Discos de lijado de carburo de silicio para poliestireno - pack de 50

With a coarse P36 grit and razor-sharp silicon carbide abrasive, these 225mm discs slice through polystyrene and insulation foam with aggressive stock removal and minimal clogging. The open-coat design and multi-hole pattern keep dust flowing, while the heavy E-paper backing delivers the flexibility needed for contour sanding on drywall and soft plasters.

Overview

The KLINGSPOR PS19EK sanding disc is engineered specifically for polystyrene, insulation materials, soft plasters, fillers, and drywall. Each pack contains 50 discs with a hook-and-loop (Velcro) backing for fast changes on orbital and drywall sanders. The synthetic resin bonding and silicon carbide grain ensure high durability and a long service life, even under demanding jobsite conditions.
