Conquer Commercial Demolition with Pro-Grade Flat Chisel Punching Power

Supercharge your crew's productivity and maintain an unstoppable workflow on large-scale jobsites with the Bosch HS1911B20 12-Inch SDS-Max® Flat Chisel Bit 20-Pack. 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 scale or spatter, 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.

Forged 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.

Key Features

• 20-Piece Contractor Fleet Box: Provides high-volume construction and demolition crews an uninterrupted supply of heavy consumables across the jobsite.
• 1-Inch Linear Cutting Edge: Delivers exceptional directional control for clean concrete trenching, localized slab channeling, and precise edge breakouts.
• Universal SDS-Max Shank Fit: Precision-ground shank seamlessly slots into standard industrial SDS-Max hammers and Hilti TE-Y/TE-FY quick-change chucks.
• Proprietary Heat-Treat Forging: Premium industrial alloy steel formulation engineered to combat structural fatigue and eliminate catastrophic bit breaks under load.
• Monolithic One-Piece Construction: Eliminates welded joints or structural weak points, providing high impact energy transmission directly to the concrete.

What's Included

• (20) Bosch HS1911 1" x 12" SDS-Max® Heavy Duty Flat Chisel Bits

Specifications

PRO-TIP: To preserve the straight profile sharpness of your flat chisel face, try starting your fractures by plunging at a slight 70 to 80-degree angle close to the edge of the concrete bed, instead of driving straight down into the dead center of an unbroken slab. Creating an adjacent air relief gap using this slight angle triggers clean spalling lines much faster and safeguards your tool from overheating or binding inside the masonry substrate!
