Husqvarna Diamond Core Drill Bit 542788533 3/4 Inch B1420 Elite (24 Inch Tube 5/8-11 Thread Wet Cutting Reinforced Concrete Flint Masonry)

Husqvarna 542788533 3/4 Inch B1420 Elite Diamond Core Drill Bit

The Husqvarna 542788533 is a 3/4-inch diameter wet-cutting diamond core drill bit engineered to penetrate deep structural walls, foundations, and reinforced concrete containing flint and hard aggregate. Built with a 24-inch extended tube length and a 5/8"-11 threaded connection, this B1420 Elite-Drill series bit executes deep single-pass core drilling without barrel extensions or drilling wobble. Featuring a continuous crown segment design and high-grade diamond bond matrix, it operates safely under 2 HP to 5 HP drill motors to maintain fast cutting speeds through rebar and masonry.

Best Used For:

• Deep Foundation Structural Penetration: Drilling continuous 3/4-inch core holes through 24-inch thick reinforced concrete footings and retaining walls in a single pass.
• Chemical Doweling & Anchor Bolt Hole Drilling: Boring straight, clean 0.75-inch anchor pilot holes in hard flint and chert aggregate concrete for structural tie-ins.
• Electrical & Utility Conduit Runs: Executing vibration-free wet core cuts for small-diameter electrical conduits, sensor lines, and plumbing pipes through masonry.

Key Performance & Safety Features

• 24-Inch Extended Tube Reach: Provides continuous core travel to complete deep drilling operations without core barrel extension chatter or downtime.
• Elite-Drill B1420 Gold Matrix: Formulated with a specialized diamond-to-metal bond designed to cut hard flint aggregate without segment glazing.
• Continuous Crown Segment Design: Solid ring cutter geometry delivers smooth hole starts, reduced vibration, and high rotational torque stability.
• Heavy Rebar Penetration Capacity: High-density industrial synthetic diamonds shear through high-tensile steel reinforcing rebar embedded in concrete.
• Industry-Standard 5/8"-11 Thread: Screws directly onto standard handheld and rig-mounted electric or hydraulic core drill motor spindles.
• Wet-Cooling Hydro Alignment: Designed for continuous water coolant flow to flush slurry rapidly and prevent thermal expansion bound in deep holes.

Technical Specifications

Pro-Tip: Maintain generous water supply pressure and steady linear feed pressure throughout 24-inch deep cuts; stopping water flow mid-cut in deep flint aggregate can cause diamond segments to overheat and glaze over immediately.
