## Summary description

HSS drill bit DeWalt DT5554 with 8.5 mm diameter, designed for drilling metal and other suitable materials. Made from high-speed steel (HSS) for wear resistance and durability. Compatible with standard drill chucks; suitable for workshop, construction and maintenance tasks. Provides precise holes and consistent performance for professional and DIY use.

## Long description

DeWalt DT5554 8.5 mm HSS drill bit is a high-speed steel cutting tool designed for drilling precise holes in metal and other suitable materials. The 8.5 mm diameter provides a mid-range hole size commonly used in workshop, construction and maintenance tasks. The bit is compatible with standard drill chucks and is intended for use in handheld and bench drills where HSS performance and wear resistance are required.
Advantages
The HSS construction delivers a good balance of hardness and toughness for drilling through mild steel, stainless steel in thin sections, non-ferrous metals and other machinable materials. Heat resistance in the cutting edge reduces wear during continuous drilling, while the ground flute geometry promotes reliable chip evacuation and stable drilling. The standard straight shank fits most chucks for quick bit changes and straightforward setup.

Key specifications
Material: high-speed steel (HSS)
Diameter: 8.5 mm
Shank type: straight shank for standard drill chucks
Tip/point: ground point geometry for stable centering
Flute: helical flute for chip removal
Typical applications: metal, non-ferrous metals, some plastics
How to use
Secure the drill bit in the chuck, ensuring the shank is fully seated and the chuck is tightened. Select an appropriate drill speed for the material: lower speeds for harder metals and higher speeds for softer metals and plastics. Use cutting lubricant when drilling steel to improve chip flow and extend tool life. Apply steady pressure without forcing the bit; withdraw periodically for chip clearing on deep holes. After use, clean chips from the flutes and store the bit in a dry place to prevent corrosion.
Usage recommendations
For best results when drilling metal, use a cutting fluid and moderate speed, start drilling with a pilot mark or center punch for accurate positioning, and progressively increase pressure as the tip enters the workpiece. Inspect the bit for wear before each use and replace when the cutting edge becomes blunt or chipped.
