Description
The Klingspor 147838 PS 33 CK is a high-performance self-fastening sanding disc designed for precision finishing and material removal. Featuring a 5-inch diameter and a standard 8-hole (GLS 5) vacuum pattern, these discs are engineered with a semi-open aluminum oxide grain coating and a specialized stearate layer. This unique combination significantly reduces clogging and loading, making them exceptionally effective for sanding paint, varnish, filler, and wood. The latex-impregnated paper backing provides the perfect balance of flexibility and tear resistance, ensuring a long service life even under strenuous industrial use.
Performance Features
- Non-Loading Stearate Coating: Specialized surface treatment prevents dust and debris from clogging the grit, extending the disc’s life.
- Semi-Open Grain Distribution: Optimizes chip clearance for high-speed stock removal on soft and medium-hardness materials.
- Premium Aluminum Oxide: Annealed grain structure offers increased aggressiveness and consistent sanding performance.
- High Flexibility: Latex-impregnated C-weight paper backing conforms to curved surfaces without cracking or tearing.
- Universal Compatibility: The 8-hole GLS 5 pattern fits most common 5″ random orbital sanders for superior dust extraction.
