Husqvarna 595934201 2.25 Inch x 24 Inch B10 Vari-Drill Diamond Core Bit

The Husqvarna 595934201 is a 2.25-inch overall diameter wet diamond core drill bit engineered to execute continuous deep utility penetrations through hard reinforced concrete, rebar-embedded retaining walls, and heavy masonry structures. Built with an extended 24-inch steel core barrel, this Silver-level B10 Vari-Drill series tool incorporates six laser-welded diamond segments measuring 0.95 x 0.14 x 0.4 inches to facilitate instant bit tracking and smooth, chatter-free hole starting. Equipped with a standard 1-1/4-inch - 7 threaded hub connection, it operates efficiently under continuous water cooling with core drill rig motors rated between 2 HP and 5 HP, delivering straight core extractions for specialized piping, conduit runs, and heavy anchor bolts without barrel extensions.

Best Used For:

  • Specialized Conduit & Piping Penetrations: Boring precise 2.25-inch (57mm) clearance holes through thick concrete foundation walls and floor slabs for utility lines and mechanical anchors.
  • Steel-Reinforced Concrete Coring: Penetrating heavy steel rebar mesh and hard-cured aggregate concrete containing granite, flint, and limestone without segment shear.
  • Deep Wall & Barrier Penetrations: Completing continuous 24-inch deep core extraction passes in structural masonry and retaining walls in a single setup.

Key Performance & Safety Features

  • Extended 24-Inch Core Barrel Depth: Deep-reach barrel capacity eliminates the need for bit extension rods during thick wall and slab coring operations.
  • Six Laser-Welded Diamond Segments: High-integrity laser welding joins diamond cutting segments directly to the steel tube for maximum safety under high torque.
  • Soft-Start Segment Contour: Specialized segment shape reduces initial friction and vibration to ensure rapid, precise hole starts.
  • 0.4-Inch Segment Height Matrix: Generous matrix height paired with industrial diamonds delivers elevated cutting speed and extended wear resistance.
  • Standard 1-1/4"-7 Threaded Hub: Universal female thread connection fits directly onto standard commercial core drilling rig spindles.
  • Wet-Only Coolant Circulation: Designed for continuous water flow to flush slurry, prevent bit binding, and maintain cool segment temperatures.
