Drill bit Tvardy HSS for metal 6.00 mm — black‑gold finish

Tvardy HSS drill bit for metal, 6.00 mm diameter, with a black‑gold surface finish. Made from high‑speed steel (HSS), this drill bit is intended for cutting precise holes in steel and a range of ferrous and non‑ferrous metals. The black‑gold coating improves wear resistance and reduces friction during drilling. The bit is compatible with both hand drills and drill presses, suitable for workshop, construction and maintenance applications where accurate, clean holes are required.

Advantages

The HSS material provides a balance of hardness and toughness that enables effective drilling into metals while maintaining edge stability. The black‑gold surface finish enhances durability by offering additional protection against wear and heat, helping to extend the lifetime of the cutting edge. A 6.00 mm diameter offers a common, versatile size for through‑holes and pilot holes in metalworking. The geometry of the tip and flutes is designed to evacuate chips efficiently and support steady drilling performance in handheld and machine setups.

Suitable for

• Drilling holes in steel, stainless steel, aluminum and other ferrous and non‑ferrous metals
• Use with hand drills for on‑site or maintenance tasks
• Use in drill presses for workshop and fabrication work
• Preparing holes for bolts, rivets and threaded inserts

Key specifications

• Material: High‑speed steel (HSS)
• Diameter: 6.00 mm
• Surface finish: black‑gold coating for improved wear resistance
• Intended materials: ferrous and non‑ferrous metals (including steel and aluminum)
• Compatibility: suitable for hand drills and drill presses

How to use

Secure the workpiece and mark the drilling point. For best results, use a center punch to prevent walking and select the appropriate drill speed for metal—lower speeds for harder steels and higher speeds for softer alloys. Fit the 6.00 mm Tvardy HSS bit firmly in the chuck and ensure it is properly aligned. Apply steady, even pressure and allow the drill bit to cut without excessive force; withdraw periodically to clear chips if drilling deep holes. Use cutting fluid or lubricant when drilling harder materials to reduce heat and extend tool life.

Usage recommendations

Store the drill bit in a dry place and avoid impacts to the cutting edge. For prolonged performance on hard steels, use appropriate cutting fluids and reduce feed rate. Replace the bit when signs of wear or dulling appear to maintain hole quality and avoid damaging the workpiece.
