## Summary description

SDS‑MAX drill bit DeWalt DT6790‑QZ with a 55 mm diameter for use in rotary hammers with SDS‑MAX shank. Designed for drilling large holes in concrete, masonry and stone.

## Long description

SDS‑MAX drill bit DeWalt DT6790‑QZ, 55 mm Diameter is a heavy‑duty core drilling accessory for rotary hammers with an SDS‑MAX shank. It is engineered for creating large diameter holes in concrete, masonry and natural stone where stable centring and fast penetration are required. The bit combines a reinforced tip geometry with a robust flute profile to support controlled chip removal and reliable performance under sustained load.
Advantages
The reinforced tip geometry improves centring and reduces walking on hard surfaces, while the robust flute design evacuates dust and debris efficiently to maintain cutting progress. The SDS‑MAX connection ensures secure tool engagement and quick tool changes. Constructed for high mechanical stress, the bit maintains shape and cutting capability during repeated use in demanding applications.
Suitable for
Drilling large holes in reinforced and unreinforced concrete
Creating openings for plumbing and drainage installations
Making passage holes for electrical conduits and cable ducts
Core boring in masonry and natural stone for fixture anchoring
Key specifications
Shank type: SDS‑MAX compatible shank for rotary hammers
Diameter: 55 mm suitable for large‑diameter holes
Tip geometry: heavy‑duty cutting head designed for durable centring and penetration
Flute design: reinforced spiral flutes for efficient dust and chip evacuation
Intended materials: concrete, masonry and natural stone
Typical application: rotary hammer drilling under high load conditions
How to use
Select a rotary hammer with SDS‑MAX chuck and set the tool to the drilling mode appropriate for the host material. Mark the drilling location and, if necessary, start with a smaller pilot hole to improve guidance. Insert the SDS‑MAX shank into the tool until it locks, then position the bit perpendicular to the surface and apply steady axial pressure while allowing the tool and the bit’s cutting geometry to do the work. Periodically withdraw the bit to clear dust and check progress; for deep holes use step drilling or intermittent withdrawal to maintain cooling and chip removal. Follow the rotary hammer manufacturer’s recommendations for speed, impact energy and appropriate safety measures.
Usage recommendations
Use with appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a vacuum where possible. When drilling reinforced concrete, proceed cautiously and consider a carbide‑tipped or specially rated bit if encountering significant rebar. Store the bit in a dry place and avoid excessive lateral forces to preserve tip geometry and flute integrity.
