Rubi 12mm Drygres Premium Diamond Drill Bit – 06929

Description

TheRUBI DRYGRES PREMIUM 12 mmdiamond drill bit is designed fordrilling holes in hard ceramic tiles,it is also suitable for drilling holesin natural stone (e.g. granite, marble).It is designed for drydrilling with an angle grinderor 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 arehigh drilling speed and extra long service life. Thecrown diameter is 12 mm.

There is a cavity in the centre of the crown which is filled withwax.During drilling, the wax begins to melt due to the rising temperature and thusensures 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.
