Bosch HCST006 6-Piece SDS-Plus Bulldog Carbide Rotary Hammer Drill Bit and Chisel Set

The Bosch HCST006 6-Piece SDS-Plus Bulldog Carbide Rotary Hammer Drill Bit and Chisel Set operates as a heavy-duty masonry drilling, chiseling, and light demolition system engineered to bore anchor holes and chip mortar in poured concrete, brick, and stone. Featuring custom Bosch tungsten carbide tips, an SDS-plus shank profile, a centric tip design, and inclusion of flat and point chisels, this 6-piece kit delivers up to 15% faster operational speeds than prior generations. Housed inside a Brute Tough impact-resistant carrying case and weighing 1.42 pounds, these German-manufactured bits range from 5/32-inch to 3/8-inch diameters to enable precise hole starts and surface channeling.

Best Used For:

  • Concrete Drop-In & Tapcon Anchor Drilling: Boring 5/32-inch, 3/16-inch, 1/4-inch, and 3/8-inch anchor holes in concrete slabs and masonry walls.
  • Mortar Removal & Brick Channeling: Utilizing the SDS-plus point and flat chisels to break up stubborn mortar joints, chip tile, and clear conduit channels.
  • Precision Hole Starting on Poured Concrete: Starting holes on smooth concrete surfaces using the centric tip geometry to eliminate bit walking.

Key Performance & Safety Features

  • 15% Faster Operational Drilling Speeds: Optimized bit flute geometry flushes concrete dust rapidly to accelerate drilling production.
  • Bosch Custom Tungsten Carbide Tips: Thermally hardened carbide tips resist impact fracture and wear when contacting hard aggregate in concrete.
  • Thermal-Hardened Brazing Process: Special heat-treating process fuses carbide heads to steel shanks to prevent head separation under impact.
  • No-Slip Centric Tip Profile: Precision-ground center point guides bit starts on slick masonry without drifting off mark.
  • Universal SDS-Plus Keyless Shank: Standard SDS-plus shank configuration fits all SDS-plus rotary hammers for tool-free bit swaps.
  • Brute Tough Storage Organizer: High-impact resin storage case shields bit tips during transport and keeps demolition chisels organized.
