Description
The Klingspor 147644 (PS 33 BK) is a high-performance, self-fastening sanding disc engineered for precision surface finishing on paint, varnish, filler, and wood. Designed for use with random orbital sanders, this 5-inch disc features a specialized semi-open coating and a premium aluminum oxide grain that ensures a high removal rate while resisting premature clogging. The B-weight paper backing provides the perfect balance of flexibility and tear resistance, making it an essential abrasive for automotive refinishing and fine woodworking applications.
Performance Features
- Advanced Stearate Coating: Significantly reduces loading and clogging, extending the service life of the disc during fine grit applications.
- Semi-Open Grain Distribution: Optimizes dust extraction through the 8-hole pattern, maintaining a cooler sanding surface.
- Heat-Treated Aluminum Oxide: Provides high aggressiveness and consistent scratch patterns for a superior surface finish.
- Hook & Loop (Velour) Backing: Ensures rapid disc changes and a secure, flat bond to the backing pad for vibration-free operation.
- Versatile Material Compatibility: Optimized for varnish and paint, but highly effective on plastic, stainless steel, and aluminum.
