Drill bit Tvardy HSS M2 2.5 mm extended black-gold for metal

Tvardy HSS M2 2.5 mm extended black-gold drill bit for metal is a hardened high-speed steel cutting tool designed to produce precise 2.5 mm holes in steel and other metals. The extended length provides access to deeper or recessed workpieces, while the black-gold surface finish improves wear resistance and chip flow. This drill bit is compatible with handheld drills and drill presses and is intended for workshop and industrial metalworking tasks.

Advantages

The HSS M2 material ensures durability and heat resistance during continuous drilling of metal, helping maintain cutting performance and edge life. The extended shank and flute length make it easier to reach recessed holes and to work on thicker components without changing to a longer tool. The black-gold coating reduces friction and helps evacuate chips, contributing to cleaner holes and reduced tool wear. The 2.5 mm diameter provides a precise, consistent hole size for fastening and pilot-drilling operations.

Suitable for

• Drilling holes in steel, iron, and non-ferrous metals
• Pilot holes for screws and bolts
• Deeper or hard-to-reach metal workpieces
• Use in handheld drills and drill presses in workshops or industrial settings

Key specifications

• Material: HSS M2 (high-speed steel)
• Diameter: 2.5 mm
• Length: extended flute and overall length for deeper drilling (extended)
• Surface finish: black-gold coating for reduced friction and improved wear resistance
• Tip geometry: standard split point for metal drilling (point angle typical for HSS bits)

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring it is tightly clamped and centered. Select an appropriate spindle speed for the 2.5 mm HSS M2 bit and the material being drilled—lower speeds for harder steels and higher speeds for softer metals. Apply steady, moderate pressure and allow the bit to cut without forcing; withdraw occasionally to clear chips if drilling a deep hole. Use cutting fluid when drilling steel to reduce heat and extend tool life. After use, clean chips from the flutes and store the bit dry to prevent corrosion.

Usage recommendations

Use suitable personal protective equipment (eye protection and gloves) and clamp workpieces securely. Match drill speed and cutting fluid to the metal type for optimal performance and longer bit life.
