  • 【16-Piece Diamond Drill Bit Set】Upgraded with larger 9/16" and 5/8" bits for better performance on wider openings and thicker materials. Includes 14 diamond bits in 5/8", 9/16", 1/2", 3/8", 5/16", 1/4", and 3/16" (two of each), plus two carbide pilot drills for accurate, slip-free starts. This full-size range delivers clean holes or custom shapes on tile, glass, and ceramic. 1/4" hex shank enables fast, secure changes on most hand drills
  • 【35mm Extended Diamond Surface – Faster, Cleaner Grinding & Drilling】 Features an ultra-wide 35mm diamond-coated grinding surface—over 3× wider than typical 8–10mm bits—for faster material removal and smoother drilling. The high-hardness diamond resists wear and deformation, ensuring cleaner holes and longer tool life
  • 【Brazed Diamond Bonding – No Grit Loss, Longer Lifespan】 Utilizes advanced brazing to firmly fuse the diamond layer to the carbon steel body, preventing grit loss during use. This process boosts wear resistance, heat tolerance, and impact durability, delivering long-lasting, high-efficiency performance
  • 【Built-In Cooling Wax – Clean, Efficient Dry Drilling】Each core drilling bit is filled with premium cooling wax for internal heat dissipation, eliminating the need for water. It reduces overheating and wear, making dry drilling smoother, cleaner, and more convenient—ideal for both job sites and home use
  • 【Optimized for Hard & Brittle Materials – Pro-Level Accuracy】The diamond tipped drill bit set engineered for precise drilling and edge grinding in hard materials like ceramic tile, porcelain, quartz, glass, granite,stone,ceramic pots and marble.
