Thanks to its three recesses, users can easily see what and how much they are grinding. The VISION COOL is transparent while rotating, offering users a clear view of the workpiece without needing to set down the tool. The special ‘top size’ coating used for the flaps combined with the three recesses also ensures that grinding work stays even cooler. Thermal stress on the material is minimised and less tarnish colour is produced. This also reduces the need for time-consuming rework on workpieces.
