Primo Tools Suction Ring Kit — Keep the Water Where the Bit Is Wet drilling only works if the water actually stays on the cut. Squirt-bottle-and-a-prayer is how diamond bits die: t he water runs off the tile, the crown heats up, the diamonds glaze over, and suddenly you're leaning on a bit that's stopped cutting — in the middle of an expensive tile that's already on the wall. This kit fixes the problem at the source by sealing a reservoir to the tile face and holding a pool of water directly over the hole. Be clear about what it is: a water dam, not a drill guide. There's no bushing, no moving parts, nothing to align — it just contains water where you need it, which keeps the bit cool, flushes cutting debris out of the kerf, and preserves the diamond. That translates directly into faster cutting and longer bit life on ceramic, porcelain, glass, and stone. Two rings cover the common jobs: a 1-1/2" for faucet openings and a 3" for sink cutouts. Both suction down fast, refill easily, and lift off without marking the tile. Why Tile Pros Choose It True water dam: Holds water right at the drilling point Bit protection: Keeps diamonds cool, flushed, and cutting Longer bit life: Prevents the overheating and glazing that kill hole saws Two sizes: 1-1/2" for faucets, 3" for sink openings Strong seal: Sticks to smooth tile and stone, lifts off clean Refreshingly simple: No guides, no bushings, nothing to get in the way Pro tip: Press the ring down firmly on a clean, dry tile face to get a full seal before you add water, and top it up as you go — the moment the pool drops below the crown, you're dry-drilling and cooking the bit.
