DiStar Nectar 2" Diamond Grinding Cup — Chip-Free Edge Finishing, Even in Tight Spots
Grinding porcelain edges is one of the slowest, most frustrating parts of detail tile work — especially with a small, low-power grinder that bogs down, overheats, and chips the very edge you're trying to clean up. The DiStar Nectar is built to fix exactly that: a compact soft-bond grinding cup that grinds porcelain fast, smooth, and chip-free.
At 100 grit with a soft-bond diamond layer, it refines cut edges and removes tool marks with controlled, chip-free grinding — the finishing step between a rough cut and a final polish. Its high grinding performance gets the work done quickly while keeping a low-power grinder from overheating, which is exactly where cheaper cups fall apart. And at just 2" (45mm), it reaches into niches, corners, and tight detail spots a full-size cup can't touch. It runs dry, so there's no water setup to drag out for a quick edge.
Its 5.8mm bore fits Proxxon LHW/A and LWB/A and similar low-power long-neck grinders — the detail tools tile pros reach for on finish work. Mount it on the DiStar Support adapter for a rigid, stable, true-running platform, and pair it with a 45mm cutting blade like the DiStar Butterfly: cut the tile with the blade, then refine the edge with the Nectar. It works porcelain, ceramic, and natural stone.
Why Tile Pros Choose It
- Chip-free finishing: Soft-bond diamond refines edges without chipping
- Fast without overheating: High output that won't bog a low-power grinder
- Reaches tight spots: 2" (45mm) for niches, corners, and detail work
- 100 grit: The step between rough cutting and final polish
- Runs dry: No water setup for a quick edge
- Fits Proxxon and low-power grinders: 5.8mm mounting bore
- Makes the worst part of the job almost pleasant: Edge grinding, handled
Pro tip: Keep the cup moving in light, steady passes rather than leaning on it — a soft-bond cup finishes best with speed and a gentle touch, and heavy pressure just wears it faster and risks chatter. Mount it on the DiStar Support adapter for the steadiest, truest grind on a Proxxon.
