Ultra-fine finishing that follows the surface. The Proxxon K 1000 flexible sanding pads are built for the final stages of surface finishing — where you need an abrasive that conforms to uneven, curved, or complex surfaces without leaving flat spots or pressure marks. The foam body flexes to match the workpiece, the silicon carbide abrasive cuts cleanly at 1000 grit, and the net-structure backing prevents clogging from fine dust — keeping the pad cutting efficiently throughout its life. Key Specifications Grit: K 1000 (ultra-fine) 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.: 28672 Best Uses Smart-repair finishing: Final sanding on automotive and surface repair work where surface conformity is critical 3D printed parts: Smoothing layer lines and surface artifacts on FDM and resin prints without damaging fine detail Fine finishing: Pre-polish surface prep on metal, plastic, and composite materials Contoured surfaces: Any workpiece where a rigid pad would leave uneven contact or pressure marks Frequently Asked Questions What tools are these compatible with?These 50mm self-adhesive pads are designed for use with Proxxon tools that accept 50mm PSA sanding discs. Compatible with the Longneck Angle Grinder LHW/E and similar Proxxon sanding tools. Why silicon carbide instead of aluminum oxide?Silicon carbide is harder and sharper than aluminum oxide, making it more effective on hard materials like metal, ceramics, and hard plastics — and it cuts more cleanly at ultra-fine grits, which is why it's the preferred abrasive for finishing and polishing applications. What does the net structure backing do?The net (mesh) structure allows sanding dust to pass through the abrasive layer rather than accumulating on the surface — significantly reducing clogging and extending pad life compared to solid-backed abrasives. What comes after K 1000 in the finishing sequence?After K 1000, move to the felt polishing bits with a polishing compound for a final high-gloss surface on metal or plastic.
