Husqvarna Diamond Core Drill Bit 595934203 2-3/4 Inch Vari-Drill B10 (24 Inch Tube 1-1/4-7 Thread Laser Welded Reinforced Concrete Masonry Wet)

Husqvarna 595934203 2-3/4 Inch x 24 Inch B10 Vari-Drill Diamond Core Bit

The Husqvarna 595934203 is a 2-3/4-inch overall diameter wet diamond core drill bit engineered to execute continuous deep utility penetrations through hard reinforced concrete, rebar-embedded bridge decks, and heavy masonry walls. Built with an extended 24-inch steel core barrel, this Silver-level B10 Vari-Drill series tool incorporates eight roof-top shaped laser-welded diamond segments measuring 19/20 x 7/50 x 2/5 inches to facilitate instant bit tracking and smooth, chatter-free entry. 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 conduit runs, heavy utility piping, and structural anchors without barrel extensions.

Best Used For:

• Specialized Conduit & Utility Line Penetrations: Boring precise 2-3/4-inch clearance openings through thick concrete foundation walls and floor slabs for commercial utility lines, drainage pipes, and structural anchors.
• Steel-Reinforced Concrete & Bridge Deck Coring: Penetrating heavy steel rebar mesh and hard-cured aggregate concrete containing granite, flint, and limestone without segment shear.
• Deep Wall & Foundation 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.
• Eight Laser-Welded Diamond Segments: High-integrity laser welding joins diamond cutting segments directly to the steel tube for maximum safety under high torque.
• Roof-Top Soft-Start Segment Contour: Specialized segment shape reduces initial friction and vibration to ensure rapid, precise hole starts.
• 2/5-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.

Technical Specifications

Pro-Tip: Maintain constant water pressure when wet coring 2-3/4-inch penetrations through thick concrete walls to flush slurry out of the 24-inch barrel, preventing slurry packing and bit seizure.
