RUBI FORAGRES Diamond Core Bit 28 mm (Ref. 04971)

The FORAGRES diamond core bit with a diameter of 28 mm from RUBI is designed for drilling holes in hard materials such as stoneware tiles, porcelain tiles, granite, and marble. It is ideal for drilling holes for waste, water, electricity, and similar applications. The drilling depth is 30 mm. The lifespan of FORAGRES core bits is three times longer than that of Easygres bits and depends on handling and material hardness. Water cooling is required. The core bit is laser welded. For drilling, only a regular drill or a cordless drill without hammer function is needed. On average, the bit can drill about 60 holes. The maximum operating speed for the FORAGRES bit is 900 RPM.

The package contains a diamond core bit with a diameter of 28 mm.

CAUTION – Drilling into substrates (adhesives, concrete, brick, etc.) causes significant wear on the drill bit and drastically reduces its service life! It is best to use this drill bit to pierce through hard wall or floor tiles and then continue with a carbide drill bit—but without the hammer action! This way, you’ll save on the cost of diamond drill bits and increase your work speed.
