Description

The DT6770-QZ is a DEWALT 180mm long SDS-Max core drill adaptor, used to connect TCT and bi-metal core drills to SDS-Max rotary hammer drills. The 180mm length provides extended reach for drilling through thick masonry walls or for accessing confined locations where a standard-length adaptor is insufficient.
The SDS-Max drive engagement provides positive, high-energy power transmission from the hammer drill to the core drill, enabling efficient core drilling in brick, block, and lightweight concrete. Compatible with DEWALT’s range of SDS-Max-fitment core drills.
Required accessory for connecting core drills to SDS-Max rotary hammers. Suitable for HVAC, plumbing, and electrical penetration work where the longer adaptor length is needed for access or wall thickness.
