Bosch HS1909 1-3/4" x 9-1/4" SDS-max® 16-Tooth Head Bushing Tool

The Bosch HS1909 SDS-max® 16-tooth head bushing tool textures smooth masonry slabs, roughens cured concrete substrates, and strips asphalt or scale build-up to prepare surfaces for polymer overlays and anti-slip walking profiles. Forged from a single solid billet of high-grade alloy steel and hardened through proprietary induction heat treatment, this heavy-duty percussive accessory withstands intense mechanical hammer blows without fracturing tooth tips. Outfitted with a 1-3/4-inch wide 16-tooth pyramid head pattern, an overall 9-1/4-inch reach, and a precision-machined SDS-max shank compatible across all SDS-max rotary and demolition hammers, it equips concrete restoration contractors, bridge maintenance crews, and commercial landscapers with rapid mechanical surface scarification.

Best Used For:

  • Substrate Roughening and Overlay Surface Prep: Scarifying smooth concrete slabs, foundation footings, and structural bridge decks to create high mechanical bonding profiles for self-leveling underlayments and epoxy coatings.
  • Anti-Slip Pedestrian Walkway Texturing: Bushing polished precast concrete ramps, public stairs, and natural stone walkways to deliver high-traction, code-compliant non-slip finishes.
  • Architectural Masonry and Stone Dressing: Chipping decorative textures across architectural stone facades, poured-in-place concrete walls, and retaining blocks.

Key Performance & Safety Features

  • 16-Tooth Pyramid Head Geometry: Concentrates rotational hammer impact force across 16 sharp points to crush and pulverize smooth surface laitance rapidly.
  • One-Piece Solid Forged Construction: Eliminates welded joints and mechanical seams, maximizing kinetic energy transfer directly from the hammer piston to the workpiece.
  • Proprietary Thermal Heat Treatment: Hardens the steel matrix to resist abrasive aggregate wear, mushrooming, and fatigue failure in high-impact applications.
  • Universal SDS-max® Drive Interface: Fits all brands of SDS-max rotary hammers and dedicated chipping hammers with positive ball-lock retention.
  • Balanced 9-1/4-Inch Tool Length: Delivers exceptional operator control and tool stability while allowing comfortable reach during vertical wall and floor bushing passes.
  • 1-3/4-Inch Wide Square Face: Provides substantial surface coverage per impact cycle, increasing square footage production rates on expansive slab projects.
