Bosch Demolition Star Point Chisel HS1934 SDS Max R-Tec Steel Bit (16 Inch Overall Length Self Sharpening Twist Tip 15 Percent Concrete Breakout)

Bosch HS1934 SDS-max® R-Tec 16" Self-Sharpening Star Point Demolition Chisel

The Bosch HS1934 SDS-max® R-Tec 16-inch star point chisel bit fractures reinforced concrete footings, structural foundation walls, asphalt pavement, and hard stone masonry barriers. Engineered with patented R-Tec energy-diverting reflection technology, this high-performance demolition bit redirects rebound shock straight back into the work substrate to produce 15% faster material removal rates compared to conventional point chisels. Outfitted with an active self-sharpening twist star tip that delivers up to 100 hours of continuous operation without regrinding, integrated breakout wedges that resist binding deep inside fracture planes, and an Italian drop-forged alloy steel body, it equips demolition contractors, structural concrete teams, and excavation crews with maximum impact energy transfer and reduced user vibration fatigue across commercial SDS-max rotary hammers.

Best Used For:

• Reinforced Concrete Footing and Slab Demolition: Cracking structural foundation slabs, grade beams, and heavy concrete pads containing embedded steel rebar without bit sticking.
• Deep Trenching and Foundation Excavation: Breaking away cured concrete in restricted utility trenches, drainage conduits, and mechanical pipe penetrations.
• Hard Rock and Masonry Wall Demolition: Fracturing dense fieldstone, solid limestone, granite aggregate, and structural CMU block during commercial renovations.

Key Performance & Safety Features

• R-Tec Reflection Technology: Patented energy-diverting element converts percussive return shock into new impact force, increasing material removal speed by 15%.
• Self-Sharpening Star Point: Unique twisted star tip profile wears evenly to preserve a sharp cutting edge and eliminate downtime from manual sharpening.
• 100-Hour Operating Lifespan: High-endurance tip engineering provides up to 100 hours of aggressive demolition work before requiring replacement.
• Integrated Breakout Wedges: Specialized head geometry features secondary expanding ribs that initiate instant lateral stress cracks and prevent bit jamming.
• Reduced User Vibration: Disperses kinetic rebound waves forward into the concrete rather than through the tool body and operator's arms.
• Universal SDS-Max Fitment: Compatible with all standard corded and cordless SDS-max rotary hammers and demolition chipping breakers.

Technical Specifications

Pro-Tip: Allow the star-point twist tip to establish its own fracture lines rather than levering the rotary hammer; keeping continuous downward thrust lets the R-Tec reflection collar redirect shock waves into the aggregate, preventing bit jams and keeping the tip self-sharpening.
