Drill bit Tvardy HSS for metal 2.00 mm, black-gold coating

Tvardy HSS drill bit with 2.00 mm diameter and black-gold coating is designed for drilling steel and other metals. Manufactured from high-speed steel (HSS), this 2.00 mm metal drill delivers accurate, small-diameter holes for applications that require precision such as pilot holes, electronic components and fine metalwork. The black-gold surface layer enhances wear resistance and cutting performance to extend tool life in both workshop and production environments.

Advantages

The HSS material retains hardness at elevated temperatures and provides consistent cutting for metalworking. The black-gold coating reduces friction and improves chip evacuation, which helps maintain sharpness and reduces frequent regrinding. The 2.00 mm diameter offers high positional accuracy for delicate or small-scale tasks, while the straight shank fits standard drill chucks for compatibility with bench and portable drills.

Suitable for

• Drilling pilot holes in steel and non-ferrous metals
• Precision work on electronic assemblies and circuit boards (metal mounting points)
• Small metal fabrication and repair tasks
• Model making and hobbyist metal drilling

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 2.00 mm
• Coating: black-gold wear-resistant finish
• Intended use: drilling metal (steel and other metals)
• Shank type: straight shank for standard chucks

How to use

Use the drill bit in a properly secured workpiece and select a drill or drill press with a chuck that matches the straight shank. For best results in metal, start with a slow to moderate speed and apply steady, moderate pressure to avoid overheating. Use cutting fluid or coolant when drilling thicker or harder metals to extend tool life and improve hole quality. After use, clean chips from the flute and store the bit in a protective holder to prevent damage.

Usage recommendations

For precision holes, center-punch the drilling location before starting. When drilling stainless steel or other hard alloys, reduce speed and use generous lubrication. Replace the bit when wear degrades hole accuracy or when chipping is visible on the cutting edges.
