Description
The Proxxon Silicon Carbide Sanding Discs (No. 28667) are a 12-pack of 400 grit, ×50mm hook-and-loop sanding discs for the Proxxon Angle Polisher WP/E (No. 38660). At 400 grit, these are the coarsest discs in the WP/E silicon carbide range — used for the first flatting pass to remove heavier varnish runs, surface inclusions, and paint defects before progressing to finer grits.
The hook-and-loop backing allows fast disc changes without tools. Use as the first step in a three-stage flatting process: 400 grit (this disc) → 1000 grit (No. 28668) → 2000 grit (No. 28670) → polishing compound.
Applications
- First-pass paint flatting and defect removal
- Heavier varnish run removal
- Surface inclusion removal from paint and lacquer
- Initial surface preparation before finer grit sanding
