Bosch Wide Chisel HS2164 1-1/8 Inch Hex Shank 20-1/2 x 3 Inch (Concrete Scale Spatter Asphalt Removal Breaker Hammer Scaling Chisel Bit)

Bosch HS2164 1-1/8 Inch Hex Shank 20-1/2 Inch x 3 Inch Wide Scaling Chisel

The Bosch HS2164 1-1/8-Inch Hex Shank 20-1/2-Inch x 3-Inch Wide Scaling Chisel operates as a heavy-duty demolition hammer attachment engineered to strip concrete spatter, surface scale, rust, mortar slag, and localized asphalt off hard subfloors. Featuring a 3-inch wide scraping face with dual 60-degree angled tips, a 20.5-inch total length, and a 6.31-pound heat-treated alloy steel body, this scaling chisel connects to standard 1-1/8-inch hex breaker hammers. Manufactured in Italy, this long-reach chisel spreads impact force across a broad cutting edge to clean concrete forms, dig plumbing utility troughs, and lift surface scale without gouging subfloor bases.

Best Used For:

• Concrete Form & Slab Scale Cleaning: Stripping hardened concrete spatter, mortar slag, rust scale, and form coating residues off poured concrete slabs and steel forms.
• Asphalt Patching & Utility Trough Cutting: Chipping localized asphalt, cutting shallow trench borders, and clearing utility line troughs in asphalt or masonry.
• Subfloor Surface Coating Removal: Scraping thin-set mortar, tough adhesives, and surface scale from concrete foundations across commercial renovation sites.

Key Performance & Safety Features

• 3-Inch Wide Scraping Profile: Expansive cutting edge covers broad horizontal surface areas to accelerate material scaling per impact pass.
• Dual 60-Degree Angled Bevel Tips: Precision-ground dual-bevel edge allows controlled slicing beneath surface scale without digging into concrete slabs.
• Proprietary Heat-Treated Alloy Steel: Specialized heat-treatment process hardens the alloy steel core to resist structural fatigue and thermal cracking.
• Extended 20-1/2 Inch Overall Reach: Generous length keeps operators standing upright during floor-level scaling, reducing lower back fatigue.
• Universal 1-1/8 Inch Hex Shank Fitment: Standardized industrial hex shank connects directly to major electric and pneumatic breaker hammers.
• Italian Forged Engineering: Single-piece forged construction maintains edge integrity and structural alignment under continuous heavy impacts.

Technical Specifications

Pro-Tip: When scaling concrete spatter or thin-set off concrete slabs with the HS2164 wide chisel, maintain a low 30-degree working angle against the floor. Operating at a shallow angle allows the dual 60-degree bevel tips to slide cleanly under surface scale rather than driving down into the concrete foundation.
