In civil engineering, steel construction, or renovation work on facades, diamond core drilling machines are often used. These require a continuous supply of cooling water to counteract excessive heat and material wear. The GLORIA water supply device 415 stands out for its flexible application possibilities. It can be connected to both handheld and drill stand-mounted wet drilling machines, as well as to cut-off saws or similar devices. The water supply device has a capacity of 10 liters and operates at a maximum pressure of 6 bar.
