Description

The Diamond Products 10072 4-1/4 Inch Star Blue Wet Diamond Core Bit provides high-performance structural drilling for penetrating cured concrete and heavy masonry. Engineered with premium diamond segments and a specialized general purpose bond, this 13 inch deep bit facilitates rapid material removal for large scale mechanical and HVAC infrastructure projects. Featuring a standard 5/8 inch 11 UNC threaded hub, it integrates securely with professional core rigs to ensure clean through-holes and precise alignment without the need for secondary structural patching.

Best Used For:

  • Mechanical HVAC Venting: Bores precise 4-1/4 inch clearance holes through thick cured concrete slabs for large diameter ventilation ducts and airflow assemblies.
  • Structural Plumbing Routing: Penetrates heavy masonry and foundation walls to safely route high volume water supply and drainage piping.
  • Commercial Anchoring Systems: Slices through structural concrete surfaces ensuring accurate entry points for large-scale industrial hardware and anchoring installations.

Key Performance & Safety Features

  • Premium Diamond Segments: Optimized diamond concentration ensures rapid cutting speeds and extended bit life in abrasive cured concrete and hard masonry materials.
  • Extended Core Length: 13 inch usable drilling depth permits deep penetration through thick commercial walls and foundational slabs in a single pass.
  • Universal Threaded Hub: Standard 5/8 inch 11 thread integrates securely with most professional mounted core rigs and compatible handheld drilling motors.
  • Wet Drilling Application: Engineered exclusively for consistent water supply operation to maintain cooler temperatures and prevent thermal bit degradation.
  • Tubular Steel Body: Industrial-grade low carbon steel construction minimizes rotational vibration for precise, no-walk starting geometry on reinforced surfaces.
