Klingspor PS 33 BK Discs – Paper Backing, Self-Fastening for Paint, Varnish, Filler & Wood


The Klingspor PS 33 BK self-fastening discs are a professional-grade sanding solution for preparing and finishing paint, varnish, filler, and wood surfaces. Suitable for use with orbital and random orbital sanders, they combine fast cutting action with a smooth, consistent finish.


Featuring a lightweight B-weight paper backing, these discs are flexible enough to follow contours and edges while offering good durability. The aluminium oxide abrasive grain ensures sharp, even cutting performance, and the open coat structure reduces clogging—especially useful when sanding softwoods or coated surfaces. The hook & loop (self-fastening) backing allows for quick disc changes and secure attachment during use.
