The Simpson SDS-Max Flat Chisel 1 x 12 Inch is a toughened steel demolition chisel built for demanding concrete and masonry work. Engineered with an SDS-max shank for secure, tool-free bit retention in compatible rotary hammers, this flat chisel undergoes a specialized tempering process that creates a hardened, wear-resistant surface. That same surface treatment allows the chisel edge to be resharpened whenever necessary, helping professionals maintain peak cutting efficiency over the long haul. Crafted in Germany, this chisel delivers the precision and reliability that serious demolition and renovation work demands.

Key Features

• SDS-Max Shank - fits SDS-max rotary hammers for fast, secure, tool-free bit changes, so there is no downtime fumbling with chucks on the job site
• Toughened Steel Construction - a hardened, wear-resistant material composition stands up to repeated impact against concrete slabs, masonry walls, and mortar joints without premature failure
• Specialized Tempering and Surface Treatment - the treated cutting edge resists wear during heavy chiseling and can be resharpened as needed, extending the useful life of the chisel well beyond a standard untreated bit
• 1-Inch Flat Chisel Head - the flat profile concentrates force precisely, making it effective for breaking out concrete, removing mortar joints, chipping hardened materials, and surface preparation tasks
• German Craftsmanship - produced in Germany to tight manufacturing tolerances, delivering consistent performance across general concrete demolition, masonry demolition, and renovation applications

Why This Product

• Resharpenable Edge Saves Money Over Time - unlike many competing chisels, the special surface treatment on this flat chisel allows the edge to be resharpened, meaning the tool keeps performing rather than getting discarded when it dulls
• Verified Fit for SDS-Max Rotary Hammers - the SDS-max shank interface provides a positive, tool-free connection that locks securely during impact, reducing slippage and keeping energy transfer efficient during concrete and masonry demolition
• Purpose-Built for a Wide Range of Demolition Tasks - from breaking out concrete slabs and foundations to removing mortar joints and preparing masonry surfaces, this chisel is rated for the full spectrum of general demolition and renovation work professionals encounter
• German-Made Quality in a Workhorse Tool - precision manufacturing from Germany means tighter tolerances and more consistent hardness throughout the toughened steel body, so the chisel performs reliably across demanding, high-impact applications
