Description

The DT6765-QZ is a DEWALT heavy duty 2-piece TCT (tungsten carbide tipped) core drill set designed for use with SDS-Max rotary hammers and compatible drive systems. TCT core drills are used for cutting large-diameter circular holes through brick, block, and light concrete — commonly for pipe, conduit, duct, and cable penetrations through walls and floors.
The 2-piece design refers to the barrel and pilot drill assembly that fits to a compatible SDS-Max adaptor or direct drive system. TCT core drills provide clean, round holes with minimal waste material compared to hole saws, particularly in masonry and lightweight concrete block.
Requires a compatible SDS-Max core drill adaptor (sold separately). Suitable for HVAC, plumbing, and electrical installation work requiring large-diameter penetrations through brick, block, and lightweight concrete construction.
