Bosch Demolition Floor Scraper HS1918 SDS Max 6 Inch Steel Blade (25 Overall Length Forged Alloy Upright Ceramic Tile VCT Thinset Mortar Removal)

Bosch HS1918 SDS-Max® 6" x 25" Heavy-Duty Floor Scraper Assembly

The Bosch HS1918 SDS-max® 6-inch floor scraper bit strips bonded flooring materials, hardened thin-set mortar beds, vinyl composition tile (VCT), sheet linoleum, and glued-down carpet underlayment across commercial concrete slabs and subfloors. Engineered with an extra-wide 6-inch flexible alloy steel scraper blade and an extended 25-inch overall length, this high-production demolition assembly allows operators to maintain an upright, ergonomic posture while delivering maximum mechanical prying leverage. Outfitted with heavy-duty mechanical locking fasteners, a field-replaceable blade system that eliminates the expense of replacing the full drive shank, and an Italian drop-forged alloy steel core subjected to proprietary heat treatment, it equips commercial flooring contractors, tile tear-out specialists, and demolition crews with relentless scraping throughput on SDS-max combination rotary hammers and chipping breakers operating in hammer-only mode.

Best Used For:

• Commercial VCT and Resilient Floor Demolition: Stripping glued vinyl composition tile (VCT), sheet linoleum, rubber flooring, and direct-glue commercial carpets cleanly down to concrete slabs in large open floor plans.
• Hardened Thin-Set Mortar and Adhesive Removal: Scraping residual cementitious mortar ridges, floor mastic, leveling compound, and epoxy adhesives following ceramic and porcelain tile removal.
• Concrete Slab Prep and Surface Leveling: Scraping away dried drywall mud, stucco overspray, and masonry flashing to create a clean, flat concrete substrate prior to installing new floor coverings.

Key Performance & Safety Features

• Extra-Wide 6" Scraper Blade: Broad scraping span covers wide surface areas per pass, increasing demolition square-footage output over standard narrow chisels.
• Extended 25" Ergonomic Shank: Extra-long drive shaft allows operators to stand upright during floor scraping, substantially reducing lower back stress, knee strain, and fatigue.
• Cost-Effective Replaceable Blade System: Modular head design permits quick blade replacements via the HS1918RK blade kit, preserving the heavy-duty drive shank indefinitely.
• Proprietary Thermal Heat-Treatment: Multi-stage hardening metallurgy provides superior core tensile strength, resisting fatigue breaks under continuous high-joule percussion.
• Vibration-Proof Locking Hardware: Heavy-duty bolt-and-nut clamping system prevents the scraping blade from loosening under continuous high-frequency hammer vibration.
• Universal SDS-Max Fitment: Compatible with all standard corded and cordless SDS-max rotary hammers and dedicated demolition chipping breakers operating in hammer-only mode.

Technical Specifications

Pro-Tip: Take full advantage of the 25-inch shaft length by keeping your rotary hammer handle near waist height while keeping the 6-inch blade tilted at a shallow 15- to 20-degree angle; this flat attack plane shears floor mastic and VCT cleanly off concrete subfloors without gouging the slab or stressing your lower back.
