Bosch HS2163 1-1/8 Inch Hex Shank 20 Inch Heavy-Duty Narrow Demolition Chisel

The Bosch HS2163 1-1/8-Inch Hex Shank 20-Inch Narrow Chisel operates as a heavy-duty demolition hammer attachment engineered to penetrate concrete slabs, start core anchor holes, and channel utility trenches in masonry. Featuring a high-carbon steel straight-edge blade, a 20.0-inch overall length, and a forged alloy steel body, this narrow chisel connects to standard 1-1/8-inch hex breaker hammers. Manufactured for high-impact commercial demolition, this long-reach chisel focuses impact energy onto a concentrated contact point to fracture dense concrete foundations without damaging adjacent structural surfaces.

Best Used For:

  • Concrete Slab Trenching & Channeling: Cutting precise utility line channels and pipe trenches through thick concrete foundations and subfloors.
  • Masonry Core & Anchor Starting: Concentrating breaker hammer energy to start anchor holes and core penetrations in dense poured concrete and stone.
  • Deep-Level Foundation Demolition: Utilizing the 20-inch extended length to reach down into deep footings and trenches while maintaining an upright operator stance.

Key Performance & Safety Features

  • Concentrated Impact Face: Narrow chisel profile focuses total hammer impact force to break through high-PSI concrete slabs rapidly.
  • 20-Inch Extended Overall Reach: Long body length allows operators to maintain an upright posture during floor breaking, reducing lower back strain.
  • Universal 1-1/8 Inch Hex Shank Fitment: Standardized industrial hex shank connects directly to major electric and pneumatic breaker hammers.
  • High-Carbon Steel Cutting Edge: Thermally hardened cutting edge holds straight-line tracking accuracy under continuous heavy impact.
  • Forged Alloy Steel Metallurgy: Single-piece forged alloy steel body resists mechanical bending, thermal cracking, and fatigue under heavy impacts.
  • Controlled Fracturing Geometry: Straight edge profile channels impact force along target break lines to prevent unwanted cracking in adjacent concrete.

Pro-Tip: When trenching or channeling concrete slabs with the HS2163 narrow chisel, drive the bit at a 70-degree angle rather than straight down at 90 degrees. Angling the 20-inch chisel directs impact energy forward to spall out concrete chips along target score lines without binding the tool in the trench floor.
