Product Snapshot
The 1-1/4" Narrow Chisel Jackhammer Bit is an 18-inch demolition tool designed for precision breaking and chipping work in concrete, asphalt, and masonry. This narrow-profile chisel concentrates impact force into a smaller cutting edge for controlled material removal in confined spaces or along seams.
Manufactured by Brunner & Lay from high-quality steel, this bit undergoes heat treatment in modern furnaces to deliver the hardness, impact strength, and durability required for demanding demolition work. The narrow chisel design provides superior control compared to wider bits when working around rebar, creating expansion joints, or removing material in tight areas. The 1-1/4" hex shank fits standard jackhammer chucks, while the 18-inch length provides reach for deep cuts and trench work.
Key Features
- Heat-Treated Steel Construction — Modern furnace heat treatment creates optimal hardness and impact resistance for extended service life.
- Narrow Chisel Profile — Concentrated cutting edge delivers precision control for detailed demolition work and confined-space applications.
- 1-1/4" Hex Shank — Universal fit for standard jackhammer and breaker hammer chucks.
- 18-Inch Working Length — Extended reach for deep cuts, trench work, and hard-to-access areas.
- Impact-Optimized Design — Engineered geometry transfers maximum force from hammer to workpiece while minimizing bit wear.
Applications
Used by concrete contractors, utility crews, and demolition professionals for asphalt cutting, concrete removal along expansion joints, breaking around rebar and utilities, creating control joints, and precision demolition work where a narrow cutting profile is required. Ideal for road repair, foundation removal, and utility trench work.
