Rubi 20mm Drygres Premium Diamond Drill Bit - 06971

The RUBI DRYGRES PREMIUM 20 mm diamond drill bit is designed for drilling holes in hard ceramic tiles, it is also suitable for drilling holes in natural stone (e.g. granite, marble). It is designed for dry drilling with an angle grinder or with a drill using a reduction. Thanks to the vacuum welding in production and the use of high-quality materials with high diamond density, its advantages are high drilling speed and extra long service life. The crown diameter is 20 mm.

The crown has side holes designed for cooling during drilling. This results in lower temperatures and longer crown life. Adequate pressure must be applied to the crown when drilling, as excessive pressure can overheat the crown and destroy it.
