Bosch SDS-Plus® Bulldog™ Four-Cutter Tungsten Carbide Rotary Hammer Drill Bits

The Bosch SDS-plus® Bulldog™ four-cutter rotary hammer drill bits bore concentric anchor holes through steel rebar-reinforced concrete, structural CMU block, brick masonry, and tough river rock aggregates. Engineered with an impact-resistant tungsten carbide four-cutter head matrix, each bit balances cutting forces across four distinct contact edges to slice through embedded metal reinforcement without binding, tip fracturing, or aggressive torsional kickback. Outfitted with an optimized four-flute spiral channel that aggressively clears fine silica dust from deep vertical boreholes, an anti-skating precision centering tip that stops bit wandering during initial contact, and a slotted drive shank that delivers 100 percent kinetic piston impact transfer, this professional lineup equips commercial concrete contractors, mechanical installers, and structural framers with extended wear life and code-compliant anchor accuracy across all corded and cordless SDS-plus rotary hammer drills.

Best Used For:

  • Commercial Structural Concrete Anchoring: Boring round, code-compliant holes for mechanical wedge anchors, heavy-duty sleeve studs, and drop-in expansion shields in poured foundations.
  • Direct Rebar-Embedded Concrete Boring: Drilling continuously through tilt-up panels, bridge footings, and structural columns without head destruction upon striking embedded rebar.
  • Mechanical, Electrical, and Plumbing Penetrations: Penetrating dense concrete masonry units, hard river rock slabs, and structural brick walls for conduit and piping mounts.

Key Performance & Safety Features

  • Four-Cutter Carbide Head Matrix: Symmetrical multi-cutter design distributes crushing force evenly to pulverize embedded steel rebar without binding or tool lockup.
  • High-Density Tungsten Carbide: Specially formulated carbide composition withstands extreme thermal friction and high-frequency percussive impact shock.
  • Aggressive Four-Flute Spiral Geometry: Expansive dust evacuation channels pull abrasive concrete powder out of deep holes quickly to lower operating temperatures and preserve cutting edges.
  • Anti-Drift Centering Point: Precision-ground starter guide bites into smooth concrete surfaces instantly to eliminate bit walking and guarantee hole roundness.
  • Extended Cordless Runtime: Low-friction flute profile minimizes drag against borehole walls, yielding more drilled anchor holes per cordless battery charge.
  • Universal SDS-Plus Connection: Slotted quick-change drive shank seats securely into all standard commercial SDS-plus rotary hammer chucks for zero-slip torque transmission.

Pro-Tip: Never clear borehole dust by rapidly pumping the spinning bit in and out of deep holes; keep steady downward pressure and let the four-flute spiral channels pull the concrete slurry up naturally to avoid packing abrasive debris back behind the cutter head.
