The Simpson Ejector Key is a purpose-built replacement tool designed specifically for removing the centering pin from one-piece SDS-MAX core bits once coring has begun. Built by Simpson Strong-Tie, this ejector key delivers the precise fit required for SDS-MAX core bit systems that feature a centering pin - making it an essential accessory for professionals who need a reliable, dedicated solution to keep their coring operations moving without interruption.

Key Features

• Engineered for one-piece SDS-MAX core bits with a centering pin - ensures proper fit and function for the specific bit system that requires centering pin removal, eliminating guesswork on the job site
• Purpose-built centering pin removal tool - addresses the critical mid-operation step of extracting the centering pin once coring has started, so work can continue smoothly and safely
• 3/8-inch diameter construction - provides precise compatibility with applicable one-piece SDS-MAX core bit systems, reducing the risk of damage to the bit or the centering pin during removal
• Replacement-ready design - allows professionals to quickly swap in a fresh ejector key when the original is lost or worn, keeping SDS-MAX core bit tooling systems fully operational

Why This Product

• Exact-fit compatibility - designed specifically for one-piece SDS-MAX core bits with a centering pin, so buyers get a tool that works with their system rather than a generic alternative that may not perform reliably
• Fills a critical gap in the coring process - without the correct ejector key, removing the centering pin mid-operation becomes difficult and potentially damaging; having this purpose-built tool on hand protects both the bit and the workpiece
• Trusted Simpson Strong-Tie engineering - sourced from a brand professionals recognize for precision tooling accessories, giving buyers confidence that the replacement part will meet the same standards as the original
• Simple, cost-effective replacement solution - rather than replacing an entire SDS-MAX core bit assembly, this focused replacement accessory restores full functionality to an existing system at a fraction of the cost

Frequently Asked Questions

What is the CDBEJKEY ejector key designed to do?

The CDBEJKEY ejector key is designed to remove the centering pin from one-piece SDS-MAX core bits once coring has begun. Because the centering pin must be removed after coring starts, this purpose-built tool provides the precise solution needed to complete that step during SDS-MAX core bit operations.

What diameter is the CDBEJKEY ejector key?

The CDBEJKEY ejector key has a 3/8-inch diameter, which provides precise compatibility with applicable one-piece SDS-MAX core bit systems that use a centering pin.

Which type of core bits is the CDBEJKEY compatible with?

The CDBEJKEY is compatible with one-piece SDS-MAX core bits that feature a centering pin. It is not intended for two-piece SDS-MAX core bit systems, as those do not require the same centering pin removal process.
