Every tile pro knows wet work gives you the better result: cleaner edges, a cooler blade, and a lot less silica in the air. The hard part has always been getting the water there. You squeeze a spray bottle with your off hand, ask a helper to drip water from a sponge, or stop every few seconds to pump a garden sprayer back up. On a finished floor or a job with no tap nearby, running a hose isn't an option. So the cut gets made dry, and you pay for it in chips, dust, and burned-up diamonds.
The BIHUI Water Cooling System fixes the supply problem. A 2-liter tank with a built-in 3.7V battery-powered pump delivers a steady, automatic stream through a 1.6 m (about 5.25 ft) hose. Clip the hose to your tool and press start. The water keeps flowing for as long as you're working, so you never have to stop and re-spray, and you never need a cord or a faucet. Set it down beside your work and it goes wherever the job goes.
It's built to pair with the BIHUI Gooseneck Mini Angle Grinder. Clip the hose to the grinder and water flows right to the head, cooling the blade or polishing pad while you notch, profile, and polish in tight spots. Together they give you a complete BIHUI wet-detailing setup.
It's also a natural partner for the Proxxon Cordless Long Neck Angle Milling/Drilling Unit LWB/A, the precision tool for in-place notching, outlet cutouts, and edge finishing. Fit the LWB/A with the DiStar Water Guard Kit for Proxxon LWB/A, which adds splash protection and a direct water feed to the blade, and the BIHUI becomes your water source. That gives you a fully cordless wet-detailing setup with nothing tying you to a sink. Already running the Proxxon-DiStar Cut & Polish Essentials Kit? This is the piece that keeps water on the cut and polish without a free hand.
It works just as well on full-size cuts. The DiStar Mechanic Water Supply System 4.5"–5" turns a standard angle grinder into a water-fed cutter by delivering water right to the cut zone. Feed it from the BIHUI and you get a steady, powered supply instead of a sprayer you have to keep pumping by hand. You get chip-free edges and longer blade life on porcelain, ceramic, granite, and natural stone, and only a modest amount of water to clean up.
Pro tip: Fill the tank with clean water and start the flow before the blade touches the tile, because a blade that's already hot will chip the first cut. On the Proxxon LWB/A, run the lightest stream that keeps a slurry at the cut and keep water away from the tool's bearings. On a long polishing day, charge the battery before you start so the flow doesn't fade mid-pass.
