Drill bit DeWalt DT60801-QZ, length 5400 mm, single piece

DeWalt DT60801-QZ drill bit, 5400 mm long and supplied as a single piece, is designed for long-reach drilling tasks in construction and industrial settings. The bit features a solid carbide tip with four cutting faces to reduce jamming in rebar, maintain concentric holes and sustain a high drilling speed. Its long helix and optimized free space improve debris evacuation while heat-treated construction delivers the strength required for repetitive use in hard materials such as reinforced concrete, masonry and natural or artificial stone.

Advantages

The carbide tip with four cutting faces minimizes binding on rebar and preserves hole geometry, providing cleaner and more accurate results. The extended 5400 mm length enables access to deep or hard-to-reach drilling points without extensions. A long helix profile and optimized clearance help evacuate drill cuttings quickly, reducing friction and heat build-up. Heat-treated construction increases durability and resistance to wear during prolonged drilling in abrasive materials.

Suitable for

• Drilling through reinforced concrete
• Masonry drilling in walls and floors
• Working with natural and artificial stone
• Long-reach drilling in construction and renovation projects

Key specifications

• Overall length: 5400 mm
• Tip material: solid carbide with four cutting faces
• Helix: extended helix length for faster debris removal
• Construction: heat-treated body for increased strength
• Supply format: single piece

How to use

Select a compatible drill and mounting system that accept this long single-piece bit and secure the bit according to the drill manufacturer's instructions. Mark the drilling position, start at low speed to establish the hole, then increase speed and apply steady, moderate pressure to maintain centering and reduce wandering. Retract periodically if drilling deep to clear debris and allow cooling; ensure the workpiece is properly supported and secure to prevent movement.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection and dust extraction or a mask when drilling concrete and masonry. Verify that the drill and its chuck or adapter are rated for the bit's length and expected loads. For reinforced concrete, monitor for rebar contact and avoid excessive side loads; if rebar is encountered frequently, consider a purpose-built rebar-cutting solution.
