RUBI FORAGRES Diamond Core Bit 20 mm (Ref. 04970)

The FORAGRES diamond core bit with a 20 mm diameter from RUBI is designed for drilling holes in hard materials such as sintered tiles, porcelain tiles, granite, and marble. The drilling depth is 30 mm. The lifespan of FORAGRES core bits is three times longer than that of Easygres bits and depends on the handling and hardness of the material. Water cooling is necessary. For drilling, a standard drill or cordless drill without hammer function is sufficient. The bit can typically drill around 60 holes. The maximum recommended speed for using the FORAGRES bit is 900 RPM.

The package includes a diamond core bit with a diameter of 20 mm.

WARNING – When drilling into substrates like adhesive, concrete, brick, etc., the drill bit experiences significant wear and its lifespan decreases drastically! The best practice is to use this drill bit to penetrate only the hard tile or slab, then continue drilling with a carbide bit – but without hammer action! This way, you save on diamond drill bits and increase work speed.
