Clear Stubborn Overburden and Scale Fast with High-Impact Broad Scraping Precision

Streamline your heavy-duty surface preparation and site cleanup with the Bosch HS2164 20-1/2-Inch x 3-Inch Wide Chisel Breaker Hammer Bit. Forged to deliver maximum material clearance under intense trade loads, this professional-grade attachment features a robust 3-inch wide scraping face geometry engineered with dual 60-degree angles. By efficiently distributing concentrated kinetic impact energy across its wide blade edge, this heavy scaling chisel effortlessly lifts concrete spatter, surface scale, rust, hardened slag, and stubborn masonry residues. It is an indispensable demolition asset for highway infrastructure crews, masonry restoration contractors, and commercial remodelers who need a high-yield solution for cutting precise plumbing utility troughs, clearing localized asphalt, and stripping industrial coatings.

Engineered for ultimate jobsite longevity, the Bosch HS2164 is manufactured using a proprietary, advanced heat-treatment process that significantly hardens the alloy steel core while retaining necessary impact ductility. Its extended 20-1/2-inch length provides an optimized operational reach, keeping your body posture comfortably plumb and preventing excessive back fatigue during punishing downward demolition runs. Designed with standard universal brand compatibility, the precision-ground 1.125-inch (1-1/8") hex shank locks firmly into all major pneumatic jack hammers and electric breaker hammers on the market. Trust this Italian-crafted masterpiece to endure massive cyclical hammer friction without structural warping or fracture, keeping your jobsite production running at peak efficiency day in and day out.

Key Features

  • Broad 3-Inch Clearance Blade: Wide cutting face optimized to strip rust, concrete spatter, and floor scale over massive surface areas with fewer strikes.
  • Dual 60-Degree Angled Tips: Dual bevel geometry allows for pristine edge control, easily slicing beneath stubborn materials without digging into subfloor bases.
  • 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.
  • Extended 20-1/2 Inch Comfort Reach: Generous length keeps the operator upright during floor-level scraping, significantly minimizing lower back strain.

PRO-TIP: When using wide 3-inch scaling chisels on flat concrete slabs, maintain a shallow 30 to 45-degree angle relative to the surface. Striking vertically at 90 degrees concentrates all the destructive energy into a dead-end compression load against the underlying concrete, which will heavily accelerate tool wear, generate brutal hand-arm vibration feedback, and dull your dual 60-degree blade bevel prematurely!
