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.
