Drill bit Tvardy HSS for metal 3.00 mm black-gold finish (MPN T02030)

Tvardy HSS drill bit for metal, 3.00 mm diameter with a black-and-gold surface finish, is designed for creating precise holes in a range of ferrous and non-ferrous metals. Made from high-speed steel (HSS), the bit offers a balance of hardness and heat resistance for typical metalworking operations. The polished black-and-gold coating improves chip evacuation and provides additional surface protection during cutting. This single 3.00 mm drill bit is suitable for both handheld drills and drill presses when used with appropriate speed and clamping.

Advantages

The HSS material ensures wear resistance and maintains cutting performance at elevated temperatures compared with standard carbon-steel bits. The black-and-gold finish reduces friction and helps prevent built-up edge, which supports cleaner hole quality and longer service life. Its 3.00 mm diameter is useful for precision holes and pilot drilling in thin to moderate metal sheets and components. The bit’s geometry is optimized for metal drilling to provide reliable centring and consistent chip removal.

Suitable for (tasks / use cases)

• Drilling precise 3.00 mm holes in steel sheets and plates
• Pilot holes for screws, bolts, and rivets in metal assemblies
• Repairs and maintenance work on metal components
• Use in manual drilling and bench or pillar drill operations

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 3.00 mm
• Surface finish: black-and-gold coating
• Intended application: metal drilling (ferrous and non-ferrous)
• Shank type: straight round shank for standard chucks

How to use

Select an appropriate drilling speed for HSS and the thickness and type of metal being drilled; lower speeds are recommended for harder or thicker materials. Secure the workpiece firmly in a vice or with clamps to prevent movement and ensure accurate hole placement. Mark the drilling point and use a centre punch if necessary to improve centring. Use cutting fluid or lubricant to reduce heat and improve chip evacuation, especially when drilling stainless steel or other hard alloys. Apply steady, moderate feed pressure and clear chips periodically to avoid clogging the flutes.

Usage recommendations

For best results, start with slower speeds and increase only if chip formation indicates safe cutting temperature. Replace the bit when wear or chipping affects hole quality. Store the drill bit dry and protected to preserve the coating and cutting edge.
