Husqvarna Millenium® B610/B5300 Prestress | Core Drill Bit

Core drilling through prestressed concrete demands bits engineered to handle high-tension steel reinforcement without wandering or binding. The Husqvarna Millenium® B610/B5300 Prestress Core Drill Bit delivers consistent performance in post-tension and pre-tension concrete applications where standard bits fail. Its specialized diamond matrix cuts through embedded steel cables and rebar while maintaining straight holes in structural members. The design reduces bit deflection during deep drilling operations, keeping your holes on target through heavily reinforced sections. Fast cutting speed means less time per hole on commercial structural work, bridge decks, and parking garage retrofits. Built for concrete cutting contractors and drilling specialists working on reinforced structural projects where precision and durability matter.
