Description

The Diamond Products 09989 1.5 Inch Star Blue Wet Diamond Core Bit delivers high-performance structural drilling for penetrating cured concrete and heavy masonry. Engineered with a specialized BOL bond and premium diamond segments, this 13-inch deep bit provides rapid material removal for commercial plumbing and electrical routing. Featuring a standard 5/8-inch 11 UNC threaded hub, it integrates seamlessly with professional core rigs and handheld motors to ensure clean through-holes without the need for secondary patching.

Best Used For:

  • Commercial Plumbing Routing: Bores precise 1.5-inch clearance holes through thick cured concrete slabs for rigid pipe installations.
  • Electrical Conduit Runs: Penetrates heavy masonry and brick to route electrical conduit with minimal rotational vibration.
  • HVAC Venting Installation: Slices through structural hard materials, ensuring clean entry points for ventilation system mounts.

Key Performance & Safety Features

  • Premium BOL Bond: Optimized diamond concentration ensures rapid cutting speeds and extended bit life in abrasive hard masonry.
  • Extended Core Length: 13-inch usable drilling depth permits deep penetration through commercial walls and foundational slabs in a single pass.
  • Universal Threaded Hub: Standard 5/8-inch 11 thread integrates securely with both mounted core rigs and handheld drilling motors up to 3 inches.
  • Wet Drilling Application: Designed exclusively for consistent water supply operation to maintain cooler temperatures and prevent thermal bit degradation.
  • Tubular Steel Body: Industrial-grade construction minimizes vibration for precise, no-walk starting geometry on uneven surfaces.
