  • 10 Versatile Sizes: Comes with 10 essential sizes (6/8/10/12/16/20/25/35/55/68mm) to meet most drilling demands. Ideal for tile, stone, glass, porcelain, granite, and ceramic, perfect for home renovation, bathroom/kitchen upgrades, and professional projects.
  • Vacuum Brazed Diamond Technology: Advanced vacuum brazing bonds premium diamond grit to a high-quality steel core. Ensures exceptional durability, strong heat resistance, and long-lasting sharpness for smooth, effortless drilling through hard materials, no frequent replacement needed.
  • Clean & Efficient Drilling: Spiral groove design enables quick chip removal, preventing clogging for clean, smooth holes. Built-in wax coating cools and lubricates during operation, reducing friction and extending the drill bits' service life.
  • Stable Triangle Shank: Robust triangle shank fits most drill chucks (electric drills, impact drills, etc.) tightly. Eliminates slippage and wobble during high-speed drilling, ensuring precise positioning and consistent hole accuracy.
  • Dry & Wet Dual-Use: Flexible for both dry drilling (quick tasks) and wet drilling. Water cooling is recommended for prolonged use on ultra-hard materials like porcelain and granite, effectively reducing heat and protecting the bits for better results.
