Description

The RUBI DRYGRES PREMIUM diamond drill bits are designed for drilling holes in hard ceramic tiles, they are also suitable for drilling holes in natural stone (e.g. granite, marble). They are designed for dry drilling with an angle grinder or with a drill using the included adapter. Thanks to the vacuum welding in production and the use of high-quality materials with high diamond density, their advantages are high drilling speed and extra long service life.

The crowns have side holes designed for cooling during drilling. This results in lower temperatures and longer crown life. The Ø43 and 68 mm crowns have an interrupted segment with diamonds, which increases drilling accuracy.

Adequate pressure must be applied to the crown when drilling, as excessive pressure can overheat the crown and destroy it.
