The RUBI SUPERPRO diamond crown is designed for adjusting (grinding) or enlarging already drilled holes, repairing their edges or adjusting edges after cutting tiles. It is suitable for various paving materials used for landscaping, e.g. natural stone paving. It is designed for dry drilling with an angle grinder in the speed range of 6000-11000 per 1 minute. Thanks to the vacuum welding in its manufacture and the use of high quality materials with high density diamonds all around its perimeter, its advantages are high performance and durability. The holes improve the cooling of the crown. The diameter of the crown is 20 mm. The grain size of the crown surface is 50/60.

The crown is not intended for drilling new holes! Adequate pressure must be applied to the crown when drilling, as excessive pressure can overheat the crown and destroy it.
