Is your grinding wheel wobbly or the surface of the grindstone not flat? The original Einhell twist-off device is the right accessory to remedy this situation. The turning and dressing tool can be used especially with the Einhell wet sander TC-WG 200. The twist-off device is simply mounted on the grinding support of the wet grinder. With the help of the high-quality diamond tip, the grinding wheel can again be rounded and levelled. Depending on the speed of the feed, fine or coarser grooves are formed in the stone. With this dressing, the grinding wheel can be optimally prepared depending on the requirements.
