This adhesive-backed/PSA sanding disc is a net-backed abrasive intended for general-purpose sanding, stock removal and surface preparation across a range of substrates in industrial settings. Designed for use with a Hookit™ hook and loop supporting pad and vacuum extraction, it reduces airborne dust when paired with a suitable backing tool and extraction system. The abrasive combines precision-shaped ceramic with aluminium oxide for consistent cutting and finishing in workshop and production-line environments.
