Drill bit Tvardy HSS for metal 5.00 mm black-gold finish

Tvardy HSS drill bit for metal, 5.00 mm diameter, with a black-gold surface finish designed for general metalworking. Manufactured from high-speed steel (HSS), this drill bit is intended for drilling steel and other metals and is suitable for use with hand drills and drill presses. Available in multiple pack sizes, it is designed to create precise holes in sheet metal, profiles and construction components for routine workshop and on-site tasks.

Advantages

The HSS material provides a balance of hardness and toughness for consistent cutting performance in ferrous and non-ferrous metals. The black-gold surface finish helps reduce friction and improves chip evacuation while offering moderate corrosion resistance. A 5.00 mm diameter delivers a commonly used hole size for fasteners and fittings, and the geometry is suitable for standard drilling operations with both portable and stationary drilling equipment.

Suitable for

• Drilling holes in sheet metal and thin metal plates
• Creating holes in metal profiles and structural components
• Workshop and construction site drilling with hand drills or drill presses
• General maintenance and repair tasks involving steel and similar metals

How to use

Select an appropriate drill speed and feed for the metal being worked; lower speeds are generally recommended for harder steels while higher speeds suit softer metals. Secure the workpiece and, where possible, use a center punch to mark the drilling point to reduce bit wandering. Apply steady pressure and allow the HSS drill bit to cut without excessive force; withdraw periodically for chip clearance when drilling deeper holes. Use cutting fluid as needed to prolong tool life and maintain cutting performance.

Usage recommendations

For best results, use appropriate cutting fluid for the material, clamp the workpiece securely, and choose drill speeds based on metal hardness. Replace or re-sharpen bits showing wear or chipping to maintain hole quality and safety.
