Our high-quality zirconia corundum sanding triangles, measuring 82 × 82 × 82 mm and featuring a standard hook-and-loop fastening system, are the ideal choice for delta sanders and multi-tools with a smaller 82-mm chuck without a dust extraction system. Available in grits ranging from K36 to K120 in a convenient pack of 50. The self-adhesive backing (pressure-sensitive adhesive) ensures a secure, firm hold without a hook-and-loop adapter. Compatible with all standard delta sanders and oscillators with an 82-mm chuck. Direct from the manufacturer-importer at attractive prices—without any middleman markup.
💡 Does your machine have a dust extraction system? If so, our 93 × 93 mm zirconium grinding triangle with a 6-hole extraction port is the better choice. For FEIN, Bosch, and Makita multi-tools with an 80 mm hook-and-loop attachment, we recommend our 80 mm silicon carbide triangular sanding sheets.
The hook-and-loop backing ensures quick, tool-free disc changes and minimizes setup time compared to rigid screw connections on compatible machines.:
Zirconia corundum is a premium self-sharpening abrasive grain. During grinding, the grain tips fracture in a controlled manner, continuously creating new sharp cutting edges:
Our range of sanding triangles covers grits from K36 to K120 — select the right one using the variant selection:
💡 Pro tip: For best results, work your way gradually from coarse to fine—for example, K40 → K80 → K120 when sanding wooden edges and corners.
The 82-mm self-adhesive format fits all standard delta sanders, multi-tools, and oscillating tools with a compatible 82-mm mounting or self-adhesive attachment system:
Important: The triangle should be attached directly to a clean, grease-free sanding pad. If you are unsure about compatibility, please contact us with your machine model number.
As a manufacturer-importer, we produce our products in our own factories and ship them directly to Germany without any middlemen. This allows us to offer premium quality at attractive direct-importer prices—with grinding performance comparable to that of German brand manufacturers, but at significantly better terms. We already supply well-known specialty retailers in southern Germany—a clear sign of confidence in the quality of our products.
PSA stands for "Pressure Sensitive Adhesive" — a self-adhesive backing. The triangle is pressed directly onto the clean sanding pad and stays in place thanks to the adhesive. No hook-and-loop adapter is needed — ideal for machines with a smooth sanding pad mount.
The 82-mm size is designed for delta sanders with a smaller mounting surface and adhesive system. If your machine has a hook-and-loop backing pad, our 93-mm hook-and-loop triangle with 6-hole dust extraction is the right choice. If you are unsure, please contact us with your machine model number.
PSA abrasives are primarily designed for a single, secure application. Repeatedly peeling them off and reapplying them reduces their adhesive strength. For frequent changes between grits, a hook-and-loop system is more practical—see our 93-mm hook-and-loop triangle.
Zirconia is significantly harder and more durable. When grinding, the crystals fracture in such a way that new sharp edges are constantly formed—hence its long service life. Zirconia pays for itself, especially when working with hardwood and metal, because you use fewer grinding triangles.
To remove the paint, start with 36-grit or 40-grit sandpaper. Then gradually move to finer grits: 60-grit → 80-grit → 120-grit for the final sanding before repainting.
The sanding pad must be clean, dry, and free of grease. Completely remove any dust or adhesive residue from the previous triangle before applying a new one—this is the only way to ensure the PSA triangle adheres properly.
