## Summary description

The RUBI 51929 drill bit set includes 6 diamond drill bits with a diameter of 6.8 cm. Designed for effective drilling in various materials, this set offers durability and precision. Ideal for professionals and DIY enthusiasts alike.

## Long description

The RUBI 51929 6 pc Diamond drill bits 6.8 cm set contains six diamond-tipped core bits designed for clean, controlled drilling in hard surfaces. These drill bits are intended for tasks that require precise circular holes with minimal chipping, delivering consistent performance for both professional tradespeople and home users working on tile, porcelain, ceramics, glass and similar materials. The set is supplied with bits of identical diameter, each engineered to balance cutting speed and wear resistance for repeated use.
Advantages
Diamond cutting edges provide high abrasion resistance and long service life compared with conventional carbide bits. The core design facilitates effective material removal while reducing stress on the workpiece, and the uniform 6.8 cm diameter enables repeatable hole sizes without frequent tool changes. These bits are compatible with standard holders and are suitable for wet drilling methods that extend bit life and improve hole quality.
Suitable for
 Drilling circular holes in ceramic and porcelain tiles
 Cutting through glass and glazed surfaces
 Creating openings for plumbing fixtures and electrical boxes in tiled walls
 Work requiring repeatable, clean hole diameters of 6.8 cm
 Wet drilling applications to minimise dust and overheating
Key specifications
 Quantity: 6 diamond core drill bits
 Cutting diameter: 6.8 cm
 Tip material: diamond grit sintered to the cutting edge
 Suitable drilling method: wet drilling recommended
 Compatible with standard rotary drills and drill stands using appropriate adapters
 Intended materials: ceramic, porcelain, glazed tile, glass and similar hard brittle materials
How to use
Mark the required hole position and secure the workpiece to prevent movement. Use a low to medium drill speed and start with light pressure to establish the cutting contact. Wet drilling is recommended: provide a continuous water supply to the drilling area to cool the diamond edge and remove debris. Maintain steady, moderate pressure and avoid forcing the bit; allow the diamond edge to cut at its designed speed. After finishing, clean the bits and store them dry to prevent damage.
Usage recommendations
For best results, use these diamond drill bits with a drill stand or guide to ensure perpendicular alignment, and employ wet drilling to reduce heat build-up and extend tool life. Always wear appropriate eye and hand protection and follow manufacturer instructions for adapters and drill speed ranges when working with fragile materials.
