The Simpson SDS-Max Core Bit with Centering Bit 2 in x 22 in is a heavy-duty rotary hammer accessory from Simpson, purpose-built for cutting clean, precise cylindrical holes in concrete and stone. Engineered with an SDS-Max shank for secure, maximum-power-transfer tool connections, this one-piece core bit arrives ready to work alongside its included centering bit, making it a reliable choice for demanding masonry drilling tasks in combination hammer/drill mode.

Key Features

• SDS-Max Shank - Locks securely into SDS-Max rotary hammer tools for efficient power transfer and tool-free bit changes, reducing downtime on the job.
• Centering Bit Included - Guides the core bit accurately at the point of penetration during combination hammer/drill mode operation, helping maintain a true, clean bore hole from start to finish.
• Carbon Steel Construction - Provides the structural durability needed to withstand the high-impact forces generated during concrete and masonry core drilling.
• Extended 22 in. Overall Length - Gives the user the reach required to access deeper drilling positions while maintaining stable, controlled tool handling.
• 2 in. Cutting Diameter - Delivers a consistently sized cylindrical hole suited for anchor installations, conduit pass-throughs, and other precise masonry applications.
• Combination Hammer/Drill Mode Compatibility - Optimized for use in the mode that balances rotational cutting with impact force, making it effective across concrete and stone substrates.

Why This Product

• All-in-one solution out of the box - The centering bit ships as part of the package, so buyers get everything needed for guided, accurate core drilling without sourcing additional accessories separately.
• Built for professional-grade rotary hammer systems - The SDS-Max shank interface is the standard connection for high-capacity rotary hammers, meaning this bit is matched to tools designed for the most demanding concrete and masonry work.
