Engineered explicitly for commercial demolition contractors, mechanical teams, and masonry installers, these heavy-duty chisels concentrate your rotary hammer's kinetic shockwaves into a precision 1-inch flat cutting face. This linear geometry is highly effective for directional tracking, structural channeling for utility rough-ins, clearing tile and mortar, and systematically fracturing thick concrete slabs, foundation footings, and stone masonry walls. Purchasing this industrial bulk multi-pack ensures your jobsite fleet stays fully operational, minimizing tool-swap delays and keeping large construction deadlines safely on track.\u003c\/p\u003e\n\u003cp\u003eForged from a single piece of premium-grade alloy steel, each flat chisel in this commercial bundle is crafted to survive the most punishing cyclical impact forces. Bosch applies a proprietary, advanced thermal heat-treatment process that hardens the steel core to resist edge dulling while retaining proper core ductility to prevent catastrophic fracturing under extreme loads. The precision-machined universal SDS-Max® shank ensures a tight, wobble-free interface across all major heavy breaker hammer brands on the market, including Hilti systems utilizing TE-Y and TE-FY chuck configurations. Trust these Italian-forged heavy consumables to deliver optimized energy transmission straight to the work surface, generating clean fractures and rapid penetration rates day after day.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Piece Contractor Fleet Box:\u003c\/strong\u003e Provides high-volume construction and demolition crews an uninterrupted supply of heavy consumables across the jobsite.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Inch Linear Cutting Edge:\u003c\/strong\u003e Delivers exceptional directional control for clean concrete trenching, localized slab channeling, and precise edge breakouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal SDS-Max Shank Fit:\u003c\/strong\u003e Precision-ground shank seamlessly slots into standard industrial SDS-Max hammers and Hilti TE-Y\/TE-FY quick-change chucks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary Heat-Treat Forging:\u003c\/strong\u003e Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonolithic One-Piece Construction:\u003c\/strong\u003e Eliminates welded joints or structural weak points, providing high impact energy transmission directly to the concrete.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(10) Bosch HS1912 1\" x 18\" SDS-Max® Heavy Duty Flat Chisel Bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"1094\" height=\"615\" src=\"https:\/\/www.youtube.com\/embed\/I7eKEFR5t7I\" title=\"Bosch PROFACTOR™ 18V Hitman™ SDS-max® 1-9\/16 In.
