## Long description

RUBI Easy Gres 35 mm diamond core drill bit set is designed for precision drilling in hard ceramic and gres porcelain surfaces. The set provides a 35 mm cutting diameter suitable for creating clean circular openings for tile installations, sanitary fixtures and plumbing penetrations. Compatible with standard rotary drills and drill stands, the core bits are intended for use according to the drill and material manufacturer's guidance for wet or dry drilling.
Advantages
The RUBI Easy Gres set offers a durable diamond cutting edge engineered for effective penetration of dense ceramic and porcelain gres. Its 35 mm diameter ensures consistent hole size for fittings and pipe passages while reducing chipping around the hole perimeter. The design supports use with both handheld rotary drills and drill stands, giving flexibility for on-site tile work and installation tasks.
Suitable for
 Drilling holes in ceramic tiles and gres porcelain for sanitary fixtures

Key specifications
 Cutting diameter: 35 mm
 Material type: diamond-segment edge suitable for hard ceramic and gres porcelain
 Intended drilling modes: wet or dry drilling when permitted by the drill and material
 Compatible tool types: standard rotary drills and drill stands
How to use
Secure the drill bit in the chuck of a compatible rotary drill or mount it on a drill stand for greater stability. Mark the intended drilling location on the tile surface, begin at low speed to establish the cut, then apply steady, moderate pressure while maintaining tool alignment. Use water cooling when wet drilling to extend diamond life and reduce dust and heat; if dry drilling is used, follow the drill and material manufacturer's recommendations for speed, pressure and cooling pauses.
Usage recommendations
For best performance, start drilling at a low speed to prevent skidding, use a drill stand when possible for perpendicular holes, and employ water cooling during extended work on dense gres porcelain to preserve the diamond edge and reduce heat. Always wear appropriate personal protective equipment and follow safety guidance for power tool use.
