Although manufactured by Husqvarna and principally intended for use with a wide range of Husqvarna products, the WT15i is also fully compatible and suitable for use with a wide variety of disc cutters, diamond drills and other equipment manufactured by other competitor companies.
The 3m long hose supplied with the WT15i limits the frequency with which the tank needs to be physically moved whilst you work, allowing you to work without the constant interruption caused by having to continually resite the tank.
Using water as a coolant and aid/assist when cutting, drilling or grinding with diamond tool has long since been recommended as it is recognised to help to cool and preserve the life of a diamond product, facilitate a cleaner finish and provide effective dust suppression.
