RUPES No-Hole Foam Interface Pads

No-Hole Foam Interface Pads Interface pads come in two patterns, and choosing wrong costs you either dust extraction or a lot of pointless fiddling with alignment. No-hole pads have a solid foam face. There is nothing to line up, nothing to mismatch against your disc, and no hole edges pressing into the surface under load. That makes them the right pick any time you are not pulling dust: wet sanding, hand-guided work, solid-face abrasives, and finishing passes where you want the most uniform support the foam can give. Wet sanding is where these earn their keep. Extraction and water do not go together, so a perforated pad brings no benefit and only gives slurry somewhere to collect underneath. A solid face holds even support across the entire disc while you work down through a grit sequence. Available in 3", 5", and 6", each in 7mm or 12mm, two pads per pack. The 3" pairs directly with the RUPES 3" backing plate for spot repair and tight panel work, and the full range of wet sanding abrasives runs over them. If your discs are perforated and you are running extraction, you want the multi-hole version instead. What Makes it Great: 🚫 Nothing to Align: A solid face works with any disc of the same diameter regardless of its hole layout, so you are never matching patterns or discovering a mismatch after the pad is already stuck down. 💧 Built for Wet Work: No perforations means no channels for slurry to sit in and no compromised support as the pad takes on water. 🎯 Goes Down to 3": The small size handles spot repairs, tight panels, and edge work where a 5" or 6" pad simply cannot track the shape. 📐 Two Thicknesses: The 7mm keeps the disc cutting with light compliance. The 12mm trades cut for conformity when the surface curves harder than the plate can follow. Frequently Asked Questions What is the difference between no-hole and multi-hole interface pads? Dust extraction, and nothing else. Multi-hole pads are perforated so vacuum can pull through the pad, the disc, and the backing plate together. No-hole pads have a solid face for setups where extraction is not running. If you are not pulling dust, no-hole is the simpler and more reliable choice because there is no pattern that has to match. Can I use a no-hole pad with a perforated disc? Mechanically yes, the disc will attach and sand normally. What you lose is extraction, because the solid pad seals off the path between the disc holes and the plate. Dust then stays on the surface and loads the abrasive, which shortens disc life and slows your cut. Are these the right choice for wet sanding? Yes. Wet sanding does not use vacuum extraction, so perforations serve no purpose and simply trap slurry between the pad and the disc. A solid face gives consistent backing pressure from your first grit through your last. What size should I use for spot repairs? The 3" is built for exactly that work: dust nibs, runs, small refinish defects, and tight areas around badges, handles, and body lines. The 5" and 6" are for open panels where a small pad would leave uneven passes and take far longer to level an area. Can I punch my own holes in a no-hole pad? Do not. Hand-cut holes will not align with your disc or plate pattern, so extraction still will not work properly, and every cut edge becomes a place where the foam starts tearing under heat and pressure. Buy the multi-hole version if you need extraction.
