RUBI DRYGRES PREMIUM Diamond Core Bit 35 mm (Ref. 06973)

The RUBI DRYGRES PREMIUM 35 mm diamond core bit is designed for drilling holes in hard ceramic tiles and slabs, and it is also suitable for drilling into natural stone (e.g., granite, marble). It is designed for dry drilling using an angle grinder or a drill with an adapter. Thanks to vacuum welding during manufacturing and the use of high-quality materials with a high density of diamonds, it features high drilling speed and extra long lifespan. The core bit diameter is 35 mm.

The core bit has side holes designed for cooling during drilling. This helps achieve lower temperatures and extends the core bit’s lifespan. The bit features a segmented diamond pattern, which increases drilling precision. When drilling, it is necessary to apply appropriate pressure to the core bit, because excessive pressure can cause it to overheat and thus be damaged.

Improvements of the DRYGRES PREMIUM series compared to the DRYGRES series:

Faster drilling
More than twice the lifespan
Improved cooling with side holes (Ø 20-85 mm)
Core bit with segmented interruptions (Ø 43-85 mm)
