PROFESSIONAL GRADE CUTTING FOR HARD TILE AND STONE

Conquer the hardest materials on the job site with the Bosch 1-1/2 Inch Diamond Grit Hole Saw. Engineered for professional installers working with dense surfaces, this hole saw utilizes premium vacuum-brazed diamond technology to cut significantly faster and last longer than standard grit bits. It is the ultimate solution for drilling clean, precise holes in porcelain, granite, slate, glass, and ceramic tile. Whether you are installing plumbing fixtures in a stone countertop or mounting hardware in a tiled shower, this tool ensures a chip-free finish and reliable performance.

Designed for efficiency, the hole saw features segmented teeth that effectively reduce heat buildup and clear debris, preventing the binding that often occurs in stone applications. It is part of the Bosch Quick Change™ universal hole saw system, allowing you to swap sizes or types in seconds without specialized tools. To ensure the longevity of the diamond coating and the safety of the operator, this accessory is designed exclusively for wet sawing applications using machines on a GFCI-protected circuit.

Key Features

  • Vacuum-Brazed Diamond Grit: Advanced bonding technology ensures diamonds stay sharp and adhered for faster cutting and longer life.
  • Hard Material Specialist: Specifically optimized for drilling through porcelain, granite, glass, and high-PEI ceramic tile.
  • Segmented Teeth Design: Strategic gaps in the cutting edge reduce friction, dissipate heat, and improve debris removal.
  • Quick Change System: Compatible with Bosch’s universal system for rapid, tool-free accessory changes.
  • Easy Plug Removal: Side slots allow for quick ejection of material cores to keep you working efficiently.
  • Wet Cut Only: Designed for use with water cooling to preserve bit life and minimize dust.

Pro-Tip: When starting a hole in slick materials like glass or polished granite, standard pilot bits can wander and scratch the surface. To start safely, tilt the drill at a 45-degree angle to score a "crescent" into the material. Once the groove is established, slowly bring the drill upright to 90 degrees to complete the cut, keeping the surface constantly wet.
