## Long description

DeWalt DT20520 Black & Gold 5.0 mm metal drill bit is designed for drilling steel and other ferrous metals. The Black & Gold coating enhances surface hardness and wear resistance, helping to extend tool life and improve chip evacuation. With a 5.0 mm diameter and a geometry optimized for metal, this drill bit is suitable for precise holemaking in mechanical, construction, maintenance and workshop applications. It can be used in hand-held drills and drill presses on metal workpieces.
Advantages
The Black & Gold coating provides improved resistance to abrasion and helps reduce heat buildup during drilling, which supports longer service life and more consistent performance. Its 5.0 mm diameter offers accurate, repeatable hole sizes for fittings and fasteners. The flute geometry is engineered to promote efficient chip evacuation and stable drilling in ferrous materials, reducing the risk of clogging and improving hole quality.
Suitable for
 Drilling holes in mild and hardened steels
 Mechanical assembly and fastening operations
 Workshop and maintenance tasks on metal components
 Use in hand drills and bench or pillar drill presses
When it may not be suitable
This drill bit is intended for ferrous metals; it may not be the best choice for non-ferrous materials (such as aluminium or copper) where different geometries or coatings perform better. It is also not designed for masonry, wood, glass or ceramic drilling. For very high-speed applications or specialized alloys, consider carbide or coated solid-carbide variants tailored to those materials.
Key specifications
 Material suitability: ferrous metals (steel and similar)
 Diameter: 5.0 mm
 Coating: Black & Gold surface treatment for improved wear resistance
 Geometry: fluted design for chip evacuation in metal drilling
 Intended use: hand drills and drill presses
How to use
Secure the workpiece and mark the drilling point accurately. Use an appropriate center punch for precise start position if needed. Fit the 5.0 mm drill bit into the chuck and tighten firmly. Begin drilling at low to moderate speed appropriate for steel, applying steady pressure; increase speed gradually if chip removal and temperature allow. Use cutting fluid or lubricant when drilling thicker or harder steels to reduce heat and improve chip flow. Withdraw the bit occasionally to clear chips and prevent clogging.
What to consider before purchase
 Verify the bit diameter (5.0 mm) matches the required hole or fastener size.
 Confirm suitability for the specific metal type and thickness you will be drilling.
 Ensure compatibility with your drill chuck capacity and the intended drilling speed range.
 Consider whether a different material or coating (e.g., carbide) is needed for high-speed or exotic alloy work.
Usage recommendations
For best results when drilling steel, use cutting fluid, maintain moderate speeds, and clear chips frequently. Choose the 5.0 mm DeWalt Black & Gold bit when you need reliable, repeatable holes in ferrous materials using hand or bench drills.
