Shatter Aggregate 15% Faster with Self-Sharpening Viper Teeth and Reflection Technology

Dramatically accelerate your structural demolition rates and surface scaling projects with the Bosch HS1935B 16-Inch SDS-Max® R-Tec Flat Chisel Bit. Engineered with industry-leading, proprietary R-Tec technology, this premium flat chisel features an advanced energy-diverting reflection element. By dynamically absorbing your rotary hammer's severe counter-shockwaves and redirecting that kinetic energy straight back into the workload, this heavy-duty bit increases material removal speeds by up to 15 percent. Equipped with specialized "Viper" teeth along its cutting edge, it creates auxiliary localized stress fractures upon impact, making it an essential consumable asset for commercial concrete contractors, utility installers, and masonry teams.

The Bosch R-Tec system doesn't just clear thick slabs faster; it actively protects your industrial tool assets while minimizing operator fatigue. The built-in energy reflection collar dampens high-impact vibrations before they reach your hammer's internal piston assembly or the user's hands. Forged from a single block of premium-grade heat-treated alloy steel, this monolithic chisel boasts innovative self-sharpening relief grooves that keep the tip geometry perfectly sharp under brutal friction, eliminating costly resharpening breaks. Its precision-ground universal SDS-Max® shank provides a tight, low-play connection profile that fits flawlessly across major rotary hammer brands, ensuring optimized power transfer on every single plunge.

Key Features

  • 15% Greater Material Removal: Innovative R-Tec reflection architecture redirects kinetic shock forward to shatter structural concrete 15% faster.
  • Aggressive Viper Teeth Head: Unique cutting face features extra teeth profile lines to introduce secondary fracture runs in hard brick and masonry surfaces.
  • Self-Sharpening Relief Grooves: Longitudinal grooves ensure the flat chisel profile wears evenly under high-friction workloads, extending service life by up to 30%.
  • Vibration-Dampening Ergonomics: Disperses severe feedback shocks straight into the masonry substrate, keeping strain off the operator and lowering tool wear.
  • Universal SDS-Max Compatibility: Seamlessly locks into standard SDS-Max rotary hammers and demolition breakers, including Hilti TE-Y configurations.

PRO-TIP: While the advanced R-Tec profile uses integrated breakout wedges to keep the flat cutting edge self-sharpened during heavy demolition, you should avoid pulling back or levering the hammer body to snap massive, unbroken chunks of concrete like a crowbar. Relying on heavy prying angles shifts extreme structural load onto the tool's retention grooves, which can overheat your rotary hammer's quick-change chuck mechanism and risk scoring the SDS-max shank profile!
