What our Experts Think

• Complete professional dry drilling kit
  The DRYGRES Drill Bit Kit (Ref. 05996) is designed for clean, precise drilling in ceramic, porcelain, marble, and granite, making it a go-to solution for tile installers and fitters.
• Vacuum brazed diamond technology
  Uses VACUUM BRAZED diamond bonding, giving the bits strong heat resistance and longer life when drilling hard materials like porcelain stoneware.
• Multi-size versatility in one set
  Includes a range of common diameters (typically 6 mm to 50 mm depending on kit version) plus a multi-drill guide, covering most installation needs like pipes, anchors, and fittings.
• Dry cutting convenience (no water needed)
  Engineered for dry use with angle grinders or drills (no hammer mode), making it faster and more practical on job sites.
• Cleaner, more controlled drilling
  Lateral openings in the bit design help improve cooling and remove debris, reducing overheating and improving finish quality.
• Job-site ready kit packaging
  Comes in a carry case with guide system, keeping bits organized and improving accuracy for repeated drilling tasks.
• Expert insight
  Best suited for professionals who regularly install bathroom accessories, fixtures, and fittings on hard tile surfaces, where precision and speed matter more than heavy-duty core drilling depth.

Maintenance Tips

• Clean after every hole: Remove ceramic dust and slurry from drill heads to maintain cutting efficiency and prevent diamond clogging.
• Use correct speed (≤14,000 RPM): Running at proper speed reduces overheating and extends diamond life.
• Avoid dry overheating: Although “dry use” is possible, allow cooling breaks during continuous drilling to protect brazed diamond segments.
• Clear wax core (smaller bits): Let internal wax cool and re-melt during use; do not overheat to preserve lubrication performance.
• Clean side openings (larger bits): Remove debris from slots to ensure proper cooling and waste ejection after each hole.
• Inspect wear regularly: Replace bits once diamond coating is visibly reduced—performance drop indicates end of life.
• Use guide system properly: Ensure MULTIDRILL guide suction is clean for stable, precise drilling alignment.
• Store dry & protected: Keep in case to prevent impact damage, moisture corrosion, and edge dulling.
