Drill bit DeWalt DT60809-QZ, length 340 mm, 1 pc

DeWalt DT60809-QZ drill bit, 340 mm length, supplied as a single piece, is designed for drilling reinforced concrete, masonry, natural and artificial stone where extended reach is required. The solid carbide tip with four cutting faces reduces jamming in rebar, delivers cleaner, more concentric holes and maintains a high drilling speed. The long helix and optimized free space improve debris evacuation while optimized heat treatment increases bit strength for demanding professional and DIY applications.

Advantages

The four-faced solid carbide tip provides reliable cutting performance and resistance to clogging when encountering rebar, resulting in consistent hole geometry and improved drilling speed. A long helix profile combined with optimized free space accelerates removal of drilling debris, reducing friction and heat build-up. Heat-treated construction enhances durability under heavy use and helps preserve cutting geometry over extended runs.

Suitable for

• Drilling deep holes in reinforced concrete
• Creating openings in masonry and brick walls
• Working with natural stone and engineered stone surfaces
• Accessing recessed or confined drilling locations where extra length is needed

Key specifications

• Overall length: 340 mm
• Tip material: solid carbide tip with four cutting faces
• Shank type: compatible with standard drill chucks
• Helix: long helix design for improved debris removal
• Heat treatment: optimized for increased strength and durability
• Intended materials: reinforced concrete, masonry, natural and artificial stone

How to use

Fit the drill bit securely into a compatible drill chuck and ensure the shank is fully seated. Start drilling at low speed to establish a centered entry point, then increase speed as appropriate for the material. Apply steady axial pressure without forcing the bit; allow the carbide tip to cut and the helix to evacuate debris. Periodically withdraw the bit to clear accumulated dust and reduce overheating when drilling deep holes or through abrasive materials.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection and a dust mask or extraction when drilling concrete or stone. For best results, match drill speed and feed pressure to the substrate: lower speeds for harder, reinforced zones and moderate pressure to avoid tip damage. Store the bit dry and clean to maintain cutting performance.
