There are a dozen and one ways to apply water to drilling glass tanks and aquariums but none compare to the Hydrohandle. When drilling glass aquariums (and marble and stone) it is necessary to apply water to the drilling blade or bit, to keep it cool and lubricate the drill site.
The Hydrohandle is a simple accessory which attaches to the chuck of your drill, with a chuck of its own that is equipped with a special port for dispensing water. The trigger handle serves as a second site to stabilize your drill and to easily and accurately adjust the flow of water to the glass drilling site.
$95 plus shipping gets you a basic hydro handle and water attachment but since we’ve never seen any glass drill hole saws with a hollow center for channeling water, your best bet is to go for the fully loaded $295 kit with all the special hole saws and pressurized water bottle so you can make do without dragging around a garden hose.
The Hydrohandle kit is precisely the kind of great glass drilling set up for professionals who drill a lot of glass and for Reef Aquarium clubs to own and loan out to their members so that they can make better and cleaner holes in their glass aquariums. [Hydrohandle]
