  • 【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
  • 【12-Piece Diamond Drill Bit Set – Precision Drilling & Custom Milling】This tile drill bits set for ceramic includes 10 diamond bits in 1/2", 3/8", 5/16", 1/4", and 3/16" sizes (2 of each), plus 2 carbide pilot drills for accurate, slip-free starts. Perfect for drilling clean round holes or DIY custom shapes in tile, glass, porcelain, and more. Features a 1/4" hex shank for fast bit changes and a secure fit in most electric hand drills
  • 【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. Delivers smooth, accurate cuts for professional contractors and DIYers alike
