  • [42mm Extended Diamond Segment] - The extra-long 42mm diamond working section precisely repairs chipped edges from tile drilling to restore clean, smooth hole openings, while easily handling ceramic milling, deep hole drilling, and work in tight, hard-to-reach areas.
  • [Industrial Diamond Coating with Center Hole Chip Removal] - Premium vacuum brazed diamond coating delivers sharp, durable cutting with minimal grit loss. The center hole design efficiently removes chips for consistent, clean drilling on hard surfaces.
  • [Customized Structure for Stable, Anti-Break Drilling] - The 5mm bit uses a reinforced solid core for enhanced stability, anti-break performance, and precision in small-hole drilling; all other sizes have built-in cooling wax to reduce heat and prevent cracking.
  • [Dry & Wet Dual Drilling] - Supports both dry and wet drilling. Designed for high-speed operation at 1,600–5,000 RPM; excessively low speeds may shorten bit life. For continuous drilling, water cooling is recommended to improve performance and extend service life.
  • [Anti-Slip Hex Shank for Universal Compatibility] - Non-slip hexagonal handle locks tightly to avoid slipping and deviation during high-speed drilling. Fits standard drills, ideal for tile, porcelain, glass, granite, marble, and home renovation projects.
