Bosch HS1420 Bulldog™ 3/4" x 10" SDS-Plus Alloy Steel Tile Demolition Chisel Bit

The Bosch HS1420 SDS-plus Bulldog™ hammer steel 10-inch demolition chisel bit strips ceramic tile, porcelain slabs, and hardened thin-set mortar beds across concrete floors and masonry backerboard. Engineered with a precision-ground 3/4-inch angled cutting edge forged from heat-treated alloy steel, this specialized demolition accessory lifts bonded floor tiles cleanly in single intact pieces to accelerate site cleanup. Outfitted with a high-impact shank optimized for hammer-only mode on commercial SDS-plus rotary hammers, a durable profile that resists edge dulling under abrasive mortar friction, and an Italian drop-forged steel core, it equips professional flooring installers, tile remodelers, and demolition contractors with high-leverage prying velocity.

Best Used For:

  • Ceramic and Porcelain Tile Removal: Prying bonded floor tiles, quarry pavers, and wall tiles off concrete slabs and masonry backer boards in full pieces.
  • Hardened Thin-Set and Mortar Scraping: Chipping away stubborn residual mortar beds, leveling compounds, and cementitious adhesives down to clean concrete substrate.
  • Light Masonry and Concrete Scaling: Trimming concrete excess, chipping mortar spatter from brickwork, and cleaning expansion joints during surface prep.

Key Performance & Safety Features

  • High-Efficiency Prying Geometry: Engineered blade angle slips under tile layers to pop bonded ceramic and porcelain cleanly with minimal tile fragmentation.
  • Proprietary Heat-Treat Formulation: Advanced thermal conditioning provides superior tensile strength and extended operational edge retention under continuous hammer impacts.
  • Precision 3/4" Blade Width: Optimal narrow-chisel profile concentrates rotary hammer kinetic striking force for rapid material penetration without binding.
  • 10-Inch Working Clearance: Extended 10-inch shaft provides excellent standoff reach and comfortable operating angles along floors, baseboards, and vertical walls.
  • Universal SDS-Plus Fitment: Compatible with all standard corded and cordless SDS-plus rotary hammers operating in dedicated chipping/hammer-only mode.
  • Drop-Forged Alloy Metallurgy: European manufactured in Italy to rigid industrial tolerances, ensuring structural resistance against fatigue cracking and shank distortion.

  • (1) Bosch HS1420 SDS-plus Bulldog™ Hammer Steel 3/4 In. x 10 In. Demolition Chisel Bit

Pro-Tip: Maintain an approximate 20- to 30-degree working angle against the floor slab when driving under tile edges; this optimal prying plane channels the hammer's forward kinetic energy directly into the mortar bond line, popping tiles off whole without gouging the concrete substrate below.
