Husqvarna Vari-Drill B30 4-in Diamond Core Drill Bit 1-1/4-in-7 Threaded High Performance Wet Coring for Reinforced Concrete and Masonry Professional

Elite Performance in Reinforced Concrete: The Contractor’s Choice for Reliable Coring

The Husqvarna Vari-Drill B30 4" Diamond Core Bit (592881007) is the professional solution for general contractors who need a high-performance, all-round tool for demanding job sites. Engineered with a specialized medium-hard bond matrix, this bit is specifically developed to provide the longest life in medium to hard concrete with high steel reinforcement. Whether you are drilling through structural bridge decks, industrial floors, or parking garage slabs, the B30 series ensures a stable, chatter-free experience that slices through heavy rebar with precision and speed.

Optimized exclusively for wet drilling operations, the B30 utilizes advanced laser-welded straight segments (for bits up to 8 inches) to ensure maximum safety and bond strength under high-torque conditions.

Specifications

Pro-Tip: When drilling through heavy rebar, listen to your core motor. If the RPMs drop significantly, slightly reduce the feed pressure to allow the diamonds to grind through the steel without glazing. Always maintain a consistent water flow to flush out metal and concrete slurry, which prevents the bit from binding and overheating.
