Description
The Klingspor 147643 is a high-performance PS 33 CK abrasive disc specifically engineered for professional surface preparation on paint, varnish, filler, and wood. Designed for use with random orbital sanders, these 5-inch discs feature a highly durable C-weight paper backing that provides exceptional stability and tear resistance while maintaining the flexibility needed for contour sanding.
Equipped with a semi-open coating and a specialized stearate top coat, the Klingspor 147643 significantly reduces clogging and loading by preventing dust and debris from settling between the aluminum oxide grains. This results in a consistently high removal rate and an extended service life compared to standard abrasives. The GLS 5 hole pattern (8 vacuum holes) ensures efficient dust extraction, keeping the workspace clean and protecting the integrity of the finish.
