Bosch SDS-Plus Bulldog 4-Cutter Carbide-Tipped Rotary Hammer Drill Bit 5 Pack

The Bosch SDS-Plus Bulldog 4-Cutter Rotary Hammer Drill Bit 5-Pack operates as a heavy-duty percussion masonry drilling set engineered to bore anchor holes through reinforced concrete, embedded steel rebar, structural stone, and masonry block. Constructed from heat-treated alloy steel with a solid 4-cutter tungsten carbide head, these bits feature a centric starting tip that prevents bit walking and planes through rebar without binding or shattering. Outfitted with a 4-flute dust-extraction geometry, an ANSI wear mark indicator, and a standardized SDS-Plus slotted shank, this 5-piece set fits corded and cordless rotary hammers to install mechanical wedge anchors, sleeve anchors, and drop-in fasteners.

Best Used For:

  • Reinforced Concrete & Rebar Anchor Drilling: Boring precise anchor holes directly through embedded steel rebar and high-PSI concrete without bit binding or tip failure.
  • Structural Concrete Anchor Installation: Drilling clean, code-compliant holes for mechanical wedge anchors, threaded rods, and drop-in fasteners.
  • Commercial Masonry & Foundation Work: Executing high-speed rotary hammer drilling routines in poured concrete slabs, foundation walls, and structural masonry blocks.

Key Performance & Safety Features

  • Solid 4-Cutter Carbide Head: Symmetrical 4-cutter tungsten carbide tip planes through structural steel rebar without catching, binding, or chipping.
  • Precision Centric Starting Tip: Focal point tip design grips concrete surfaces immediately to eliminate bit walking and ensure accurate hole positioning.
  • High-Efficiency 4-Flute Extraction: Deep 4-flute spiral architecture evacuates concrete dust and slurry rapidly to reduce friction and lower thermal operating temperatures.
  • ANSI Wear Mark Indicator: Precision visual indicator line alerts operators when bit wear exceeds ANSI code-compliant anchor drilling thresholds.
  • Standardized SDS-Plus Slotted Shank: Slotted quick-change shank establishes a slip-free mechanical connection inside all SDS-Plus rotary hammer chucks.

Pro-Tip: Check the ANSI wear mark on the side of the Bosch Bulldog bit head periodically during heavy concrete drilling routines. Once the wear mark line vanishes due to abrasive concrete friction, replace the bit to ensure your bored holes maintain exact ANSI tolerance specs for proper mechanical anchor expansion.
