## Summary description

The DeWALT DT5550-QZ drill bit set includes 10 pieces with a diameter of 6.5 mm and a length of 101 mm. Designed for durability and precision, these bits are ideal for various drilling tasks.

## Long description

The DeWALT DT5550-QZ drill bit set contains 10 high-quality twist drill bits with a 6.5 mm diameter and a working length of 101 mm. Designed for general-purpose drilling, these bits are manufactured to provide precise hole-making performance in a variety of materials. The set is suitable for both occasional DIY users and professionals who require consistent drilling results.
Advantages
These drill bits offer consistent concentricity and a geometry that promotes efficient chip evacuation, reducing heat build-up during use. Hardened cutting edges combined with corrosion-resistant surface treatment extend service life and maintain cutting performance. The standardized 6.5 mm diameter and 101 mm length provide predictable depth control for through and clearance holes.
Suitable for
 Drilling clean holes in metal, wood and plastic (material-dependent)
 General repair, maintenance and assembly tasks
 Workshop use with hand-held or bench drills
 Producing clearance holes for fasteners and dowels
Key specifications
 Quantity: 10 pieces
 Diameter: 6.5 mm
 Overall/working length: 101 mm
 Type: twist drill bit
 Material: high-speed steel (typical for this product category)
 Finish: corrosion-resistant coating for extended life
How to use
Secure the appropriate drill bit in the chuck of a hand-held drill or drill press and tighten the chuck to prevent slippage. Select a suitable speed for the material being drilled and, if required, use cutting fluid for metal to improve cooling and chip removal. Position the workpiece securely and start drilling with steady pressure; avoid excessive force to preserve bit life and prevent breakage. After use, clean the bits and store them in their case to maintain condition.
Usage recommendations
For best results, match drill speed and feed to the material: higher speeds for wood and plastic, lower speeds with lubrication for harder metals. Inspect bits for wear or damage before use and replace when cutting edges become dull to ensure hole accuracy and safe operation.
