The Simpson 1 in x 18 in SDS-Max Flat Chisel is a heavy-duty demolition accessory built for professionals tackling concrete breaking, masonry removal, and surface chipping applications. Engineered in Germany from high-strength toughened steel, this flat chisel pairs with SDS-Max rotary hammers to deliver reliable, controlled material removal across a wide range of demanding jobsite conditions.

Key Features

• SDS-Max Shank - Locks securely into SDS-Max rotary hammers without tools, ensuring positive power transfer and a stable connection throughout heavy demolition work.
• Toughened Steel Construction - High-strength toughened steel stands up to the repetitive impact forces involved in concrete and masonry demolition, maintaining structural integrity under sustained use.
• Specialized Tempering Process - A dedicated tempering treatment produces a hardened outer surface that resists wear and extends the working life of the chisel under punishing conditions.
• Resharpenable Edge with Special Surface Treatment - The applied surface treatment supports resharpening of the chisel edge as needed, so the tool can be restored and continue performing rather than simply replaced.
• 1 in Head Width - Delivers a focused cutting width well suited to general flat chiseling, mortar removal, tile stripping, and precise surface demolition tasks.
• 18 in Overall Length - Provides extended reach for deeper cuts and gives operators more working clearance in confined or hard-to-access areas.

Why This Product

• German-engineered quality for demanding applications - Produced in Germany from toughened steel with a specialized tempering process, this chisel is built to handle repeated heavy-impact use in concrete and masonry demolition without premature wear.
• Long-term value through a resharpenable design - The special surface treatment allows the chisel edge to be resharpened when it dulls, extending usable tool life and reducing the frequency of replacement on active job sites.
• Broad application coverage in one accessory - Approved for general concrete demolition, masonry breaking, surface chipping, and removal of mortar, tile, and similar materials, making it a versatile addition to any demolition toolkit.
• Confident compatibility with SDS-Max rotary hammers - The SDS-Max shank interface provides tool-free insertion and a secure, rattle-free fit, so contractors can swap bits quickly and keep work moving without interruption.
