The final step before polish. The Proxxon K 2000 flexible sanding pads are the ultra-fine option in the Proxxon flexible pad range — designed for the last sanding pass before polishing compound is applied. At 2000 grit, they remove the micro-scratches left by coarser abrasives and leave a surface so refined that polishing compound can bring it to a true high-gloss finish. The foam body conforms to uneven and contoured surfaces, and the silicon carbide net-structure backing prevents clogging throughout the pad's life. Key Specifications Grit: K 2000 (ultra-fine — finer than K 1000) Diameter: Ø 50mm Abrasive: Silicon carbide Backing: Net structure — prevents dust clogging for extended pad life Body: Foam — conforms to uneven and contoured surfaces Attachment: Self-adhesive (PSA) Quantity: 6 pads per pack Part No.: 28674 Best Uses Pre-polish finishing: Final sanding pass before polishing compound on metal, plastic, and composite surfaces 3D printed parts: Ultra-fine smoothing of layer lines on FDM and resin prints before clear coat or polish Smart-repair: Final surface refinement on automotive and surface repair work Scratch removal: Removing micro-scratches left by K 1000 or other fine abrasives K 1000 vs. K 2000 — Which Do You Need? Both pads share the same foam body, silicon carbide abrasive, net backing, and PSA attachment — the only difference is grit: K 1000 (No. 28672): Fine finishing sander — use after heavier sanding to refine the surface K 2000 (No. 28674): Ultra-fine pre-polish — use after K 1000 to remove micro-scratches before polishing compound For best results, work through both grits in sequence: K 1000 → K 2000 → polishing compound. Frequently Asked Questions What tools are these compatible with?These 50mm self-adhesive pads are compatible with Proxxon tools that accept 50mm PSA sanding discs, including the Longneck Angle Grinder LHW/E. Do I need to use K 1000 before K 2000?Yes — jumping straight to K 2000 from a coarser abrasive will take significantly longer and may not fully remove deeper scratches. The correct sequence is: coarser abrasive → K 1000 → K 2000 → polishing compound. What comes after K 2000?After K 2000, apply polishing compound with the felt polishing disc or bullet-shape felt bit for a final high-gloss finish.
