## Summary description

The DeWALT DT5551-QZ drill bit set includes 10 pieces with a diameter of 7 mm and a length of 109 mm. Designed for efficient drilling, these bits are ideal for various materials, ensuring durability and precision in your projects.

## Long description

The DeWALT DT5551-QZ 10-piece drill bit set contains ten 7 mm diameter bits with a working length of 109 mm, engineered for general-purpose drilling tasks. These bits are designed to deliver consistent hole quality and dimensional accuracy for a range of materials commonly encountered in construction and renovation. The set is intended for use in hand-held drills and drill presses where a reliable 7 mm option is required.
Advantages
These drill bits offer stable cutting performance and extended durability through hardened steel construction and precision-ground flutes that evacuate chips efficiently. The uniform 7 mm diameter across the set ensures repeatable hole sizes while the 109 mm length provides reach into deeper workpieces. The set format guarantees spare bits for continuous work and quick replacement when wear occurs.
Suitable for
Drilling through soft and hardwood
Working with plastics and composite materials
Light to medium-duty metal drilling where 7 mm holes are required
General repair, assembly, and installation tasks
Key specifications
Quantity: 10 pieces
Diameter: 7 mm
Overall/working length: 109 mm
Material: heat-treated steel with precision-ground flutes
Tip style: twisted/standard split-point geometry for reduced walking
How to use
Select the 7 mm bit from the set and secure it firmly in the drill chuck. Use an appropriate drill speed for the material being drilled: lower speeds for metals and higher speeds for wood and plastics. Apply steady pressure without forcing the bit; allow the drill to cut at its own rate. Periodically retract the bit to clear chips and prevent clogging. When drilling metal, use cutting fluid to reduce heat and prolong bit life.
Usage recommendations
For best results, match drill speed and feed to the material, keep the bit sharp, and replace worn bits from the set to maintain hole quality. Store bits in a dry place and keep them organized to prevent damage and ensure readiness for the next job.
