VISION PRO sight lamella discs for stainless steel/steel. The VISION PRO: You always see what and where you are grinding - and this is achieved with a cool grind and a uniform grinding pattern. The temperature reduction on the surface minimizes discoloration of the workpiece, thereby reducing the need for tedious reworking. The VISION PRO is suitable for processing thin sheets and solid materials. It is ideal for surface grinding, deburring, rust removal, weld seam processing, and working on offset sheets. It is also perfectly suited for use on rounded or curved surfaces. Iron and sulfur-free.
