Bosch Demolition Hammer Chisel HS2861 1-1/8 Inch Hex Star Point Bit (16 Overall Length Self Sharpening Alloy Steel Concrete Masonry Breaking)

Bosch HS2861 1-1/8" Hex 16" Self-Sharpening Star Point Demolition Hammer Chisel Bit

The Bosch HS2861 1-1/8-inch hex 16-inch star point demolition hammer chisel bit fractures reinforced concrete slabs, thick roadway asphalt, and structural masonry walls with maximum kinetic impact efficiency. Engineered with an innovative star-point head geometry that stays sharp throughout its entire operating life, this heavy-duty demolition tool delivers a 30 percent higher material removal rate than standard conical points. Outfitted with premium heat-treated alloy steel construction tested to exceed 100 continuous working hours, an 8-inch flute length, and a standard 1-1/8-inch hex shank with retaining collar, it equips demolition contractors, concrete crews, and civil utility teams with continuous non-binding penetration and zero resharpening downtime across commercial breaker hammers.

Best Used For:

• Concrete Slab and Foundation Demolition: Breaking up thick poured slabs, structural footings, and reinforced concrete piers during heavy site remodeling and teardowns.
• Trenching and Utility Access Fracturing: Piercing compacted roadway asphalt, dense rock beds, and frozen aggregate layers for electrical conduit and plumbing pipe trenches.
• Heavy Masonry and CMU Wall Teardown: Shattering structural cinder block retaining walls, poured brick pilasters, and stone foundations with rapid localized fracturing.

Key Performance & Safety Features

• Innovative Star-Point Geometry: Concentrates demolition impact energy across multiple sharp ridges to shatter dense aggregate and prevent tool wedging.
• Continuous Self-Sharpening Architecture: Unique fluted star profile self-sharpens as it erodes, preserving its pointed profile and eliminating redressing downtime.
• 30% Faster Stock Removal: Aggressive point geometry channels breaker piston force directly to the fracture plane for increased hourly material removal.
• 100+ Hour Working Service Life: Advanced metallurgical heat treatment delivers extended fatigue resistance and structural endurance under continuous hammer strikes.
• Premium Alloy Steel Forging: High-tensile steel core absorbs intense shock waves without bending or fracturing at the shank collar.
• Universal 1-1/8" Hex Shank: Precision-machined 1-1/8-inch hex tool interface fits all standard pneumatic and electric breaker hammers for positive lockup.

Technical Specifications

Pro-Tip: Never use a star point chisel as a pry bar while it is embedded in concrete; maintain a continuous 70-to-80 degree working angle so the hammer's percussive impact does all the fracturing without putting lateral bending stress on the 1-1/8-inch hex shank.
