## Summary description

DeWalt DT6671 4 x 85 mm drill bit for masonry and concrete. Carbide-tipped, designed for use with hammer drills and rotary hammers for drilling 4 mm diameter holes to a depth of 85 mm. Suitable for installing anchors, screws and dowels in brick, block and concrete; provides efficient material removal and wear resistance.

## Long description

DeWalt DT6671 4 x 85 mm carbide-tipped masonry drill is designed for drilling small-diameter holes in brick, block and concrete. The 4 mm diameter and 85 mm working length make it suitable for common fixing tasks such as installing anchors, screws and dowels. The carbide tip and flute geometry provide efficient material removal and improved wear resistance when used with hammer drills and rotary hammers.
Advantages
The carbide tip maintains cutting performance and extends tool life compared with standard steel bits. Optimised flute design evacuates dust and debris efficiently to reduce clogging and keep drilling speed consistent. The 85 mm length ensures sufficient penetration for most anchor and dowel installations while the 4 mm diameter enables precise, small-diameter holes. Compatibility with hammer drilling modes allows use in masonry and concrete with impact action for faster progress.
Suitable for
Drilling small-diameter holes for wall plugs, anchors and screws in brick and concrete
Installing dowels and fasteners in blockwork and masonry
Preparation of pilot holes prior to fastening or rebar placement
Use with hammer drills and rotary hammers in light-to-medium masonry work
Key specifications
Diameter: 4 mm
Working length: 85 mm
Tip material: carbide
Intended material: masonry, brick, block, concrete
Recommended tool type: hammer drill / rotary hammer (impact mode)
Shank type: compatible with standard drill chucks used on hammer drills
How to use
Mark the drilling position and secure the workpiece or confirm stable surface contact. Fit the drill bit into the hammer drill or rotary hammer chuck and tighten according to the tool manufacturer’s instructions. Start drilling at low speed to establish the hole, then apply steady pressure and engage the hammer action for masonry. Retract periodically to clear dust from the hole and prevent bit binding. After reaching the required depth, withdraw the bit while the tool is running briefly to expel remaining debris.
Usage recommendations
Use personal protective equipment including eye protection, dust mask and hearing protection when drilling masonry. Select appropriate drill speed and moderate pressure; excessive force or high speed can reduce bit life. For cleaner holes and longer bit life, clear dust frequently and avoid overheating by allowing short pauses during continuous drilling.
