Blast Through Reinforced Concrete and Tough Masonry with Self-Sharpening Power

Experience a dramatic increase in jobsite efficiency with the Bosch HS2166 20-1/2-Inch Superkut Chisel. Specifically designed for high-impact 1-1/8-inch hex electric breaker hammers and heavy-duty pneumatic jack hammers, this premium demolition attachment features a unique 2-3/4-inch wide profile that is meticulously engineered to maintain a self-sharpening geometry during intense structural fracturing. By directing concentrated impact forces across its specialized cutting edge, the Superkut chisel easily busts through massive concrete slabs, reinforced structural pillars, stone wall configurations, and thick foundations. It provides commercial demolition contractors and civil engineers with an incredibly fast-penetrating solution that stays sharp up to 2X longer than standard chisels.

Built to meet the punishing demands of modern job sites, the Bosch HS2166 is forged from premium-grade alloy steel and treated with a proprietary, advanced thermal hardening process that optimizes impact resistance and limits metal fatigue. Its substantial 20-1/2-inch overall length delivers an extended operational reach, helping operators maintain a healthy, upright posture that drastically minimizes physical fatigue and back strain during long downward demolition shifts. The precision-machined 1.125-inch (1-1/8") hex shank guarantees a flawless universal brand fit, locking firmly into all standard heavy breaker hammers. This Italian-made masterpiece resists splitting and cracking under rapid, extreme vibration, minimizing tool swap downtime and keeping high-volume industrial jobs moving smoothly ahead of schedule.

Key Features

  • Premium Superkut Profile: Specialized geometric configuration accelerates concrete penetration speeds while actively maintaining its shape under heavy daily wear.
  • Self-Sharpening Edge Technology: Retains its optimized cutting and wedging capabilities far longer, requiring fewer maintenance or resharpening breaks.
  • Extended 20-1/2 Inch Reach: Generous length keeps the operator upright during floor-level demolition, significantly reducing lower back fatigue.
  • Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
  • Universal 1-1/8 Inch Hex Shank: Forged to precise tolerances for total cross-compatibility with standard pneumatic and electric heavy demolition tools.

PRO-TIP: To unlock the full self-sharpening action of the Superkut profile, ensure you change the angle of attack slightly every few strokes rather than keeping the hammer perfectly vertical. Alternating your tool lean between 75 and 90 degrees induces a natural shearing stress on the underlying aggregate, triggering faster concrete spalling while keeping the cutting tip evenly worn and raked for the next impact run!
