Bosch Demolition Hammer Chisel HS2168 1-1/8 Inch Hex Digging Spade Bit (3 Blade Width 22-1/2 Overall Length Asphalt Hard Clay Ground Trenching)

Bosch HS2168 1-1/8" Hex 22-1/2" Demolition Hammer Digging Chisel Bit

The Bosch HS2168 1-1/8-inch hex 22-1/2-inch demolition hammer digging chisel bit slices through roadway asphalt, heavily compacted caliche, hardpan clay, and frozen soil during aggressive outdoor excavation and utility installations. Engineered with an expanded 3-inch wide spade blade and an extended 22-1/2-inch total reach, this specialized breaker steel delivers optimal upright leverage while channeling high-energy percussive hammer blows straight to dense earth substrates. Outfitted with proprietary induction heat-treated alloy steel that resists abrasive edge erosion and structural fatigue, a heavy 7-pound mass for added downward impact inertia, and a standard 1-1/8-inch hex shank with retaining collar, it equips underground utility crews, asphalt paving contractors, and commercial landscapers with rapid trenching penetration and long-term durability across heavy pneumatic and electric breaker hammers.

Best Used For:

• Asphalt Pavement Slicing and Patching: Cutting clean control perimeter lines into road asphalt, driveways, and parking lots prior to backhoe excavation and resurfacing.
• Hardpan Clay and Hard Ground Trenching: Piercing and loosening compacted caliche, shale, rocky soil beds, and frozen topsoil for underground pipe, conduit, and drainage runs.
• Commercial Landscaping and Root Clearing: Chopping through dense root balls, tree stumps, and compacted earthen berms during site grading and foundation prep.

Key Performance & Safety Features

• Wide 3-Inch Spade Blade: Broad cutting profile shears through cohesive earth, clay, and asphalt far faster than narrow moil points or standard cold chisels.
• Extended 22-1/2" Overall Length: Long shaft design allows equipment operators to maintain an upright posture during deep trenching, significantly reducing back strain and fatigue.
• Proprietary Heat-Treat Metallurgical Process: Specialized thermal hardening strengthens the alloy steel matrix to prevent tip curling, chipping, or premature shank snapping under heavy impact.
• High-Tensile Drop-Forged Alloy Steel: Heavy-duty tool body absorbs continuous mechanical shock from high-draw pavement breakers without bending.
• Standard 1-1/8" Hex Retention Shank: Machined hex collar seats securely into commercial electric and pneumatic breaker hammer chucks for positive torque and blow transfer.
• Targeted Non-Concrete Design: Specifically engineered geometry optimized exclusively for earth and asphalt excavation efficiency.

Technical Specifications

Pro-Tip: When cutting asphalt or breaking hardpan caliche, angle the 3-inch spade at approximately 60 to 70 degrees to peel and fracture sections outward; never drive the blade completely perpendicular or pry backward with the breaker hammer to avoid levering stress on the shank collar.
