Description

The RUBI DRYGRES PREMIUM 8 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 8 mm.

There is a cavity in the centre of the crown which is filled with wax. During drilling, the wax begins to melt due to the rising temperature and thus ensures lubrication and cooling of the drill bit. When the wax runs out, it is recommended to replenish it – simply by using a candle. Adequate pressure must be applied to the crown when drilling, as excessive pressure can overheat the crown and destroy it.
