Core Bit Extensions & Arbors

Attach these tools to concrete and masonry core bits to extend their reach and allow for deeper drilling. These three-part systems consist of a core bit, an arbor (also known as an adapter), and an extension. Arbors drive the core bit and have an SDS plus drive shank for use with a compatible drill chuck. Use an optional extension for additional length in hard to reach areas.
