DiStar Mechanic Water Supply System (4.5"–5") — Wet-Cutting Performance Without the Saw Dry-cutting tile and stone with a grinder is a choice between bad options: clouds of silica dust, a hot blade that glazes and dies early, and chipped edges on the cuts that show. But dragging out a full wet saw for a handful of cuts — or worse, improvising with a garden sprayer, a wet sponge, and a helper — is its own kind of miserable. The DiStar Mechanic Water Supply System is the middle path: a compact attachment that turns the grinder already in your hand into a clean, water-fed cutter. The difference is where the water goes. Instead of spraying the general area and hoping, this system delivers a controlled stream right to the cut zone, so you get maximum cooling and slurry control from minimal flow. That targeted delivery is what produces the results: chip-free edges, far less airborne dust, and noticeably longer blade life, especially paired with a proper wet-cut diamond blade. Because it sips water rather than flooding the work, it's genuinely usable indoors and in finished spaces where a wet saw's mess would be a problem. It's built to fit what you already own. The attachment mounts on most 4.5"–5" (115–125 mm) angle grinders, its dual nozzle settings match 125 mm and 101.6 mm disc diameters, and a universal garden-sprayer-style connector means you feed it from a standard pump sprayer or hose — no dedicated pump to buy or haul. And when there's no tap in reach, it works great with the Hydro-Tank pump tank: pump it up once and you have a portable, pressurized water source you can carry anywhere on site — a rooftop, a finished floor, a job with the water shut off. It handles porcelain, ceramic, stone, and granite, freeing one hand for safer, more controlled cutting along the way. Why Tile Pros Choose It Water right at the cut: Targeted delivery for maximum cooling with minimal flow Chip-free edges: Wet cutting produces cleaner results than dry grinding Longer blade life: Cooling keeps the blade from overheating and glazing Less dust: Knocks down the silica cloud that comes with dry cutting Fits your grinder: Most 4.5"–5" angle grinders, dual nozzle settings for 125 and 101.6 mm discs No dedicated pump: Universal connector runs off a standard garden sprayer or hose Water anywhere: Pairs with the Hydro-Tank pump tank for a portable, pressurized supply — no tap required Indoor-friendly: Minimal water and slurry for clean, finished spaces The wet saw you didn't have to carry up three flights: Same idea, one hand Pro tip: Pair it with a blade rated for wet cutting and start your water before the blade touches the tile, not after — a blade that's already hot chips the first cut. Working away from a water source? A pressurized Hydro-Tank keeps a steady feed going anywhere. Set the nozzle to your disc size and dial the flow to the minimum that keeps a steady slurry at the cut; more water just means more cleanup for no extra benefit.
