RUBI SUPERPRO Diamond Core Bit 20 mm – Cylindrical (Ref. 06985)

The RUBI SUPERPRO series diamond core bit is designed for finishing (grinding) or enlarging pre-drilled holes, repairing their edges, or finishing the edges after cutting paving stones. It is suitable for various types of paving stones used in landscaping, such as natural stone pavers. It is designed for dry drilling using an angle grinder with a speed range of 6,000 to 11,000 RPM. Thanks to vacuum brazing during manufacturing and the use of high-quality materials with a high diamond concentration around its entire circumference, it offers high performance and long lifespan. The holes improve cooling of the core bit. The diameter of the core bit is 20 mm. The grit size of the core bit surface is 50/60.

The drill bit is not intended for drilling new holes! When drilling, it is necessary to apply appropriate pressure to the drill bit, as excessive pressure can cause it to overheat and thus be damaged.
