Drill bit Tvardy HSS M2 3.2 mm — black-gold coated extended metal drill

Tvardy HSS M2 3.2 mm is an extended-length twist drill bit engineered for metalworking applications. Manufactured from high-speed steel (HSS M2) and finished with a black-gold coating, this 3.2 mm drill provides extra reach for penetrating thicker workpieces or accessing recessed drilling locations. The geometry and coating improve wear resistance and chip evacuation compared with uncoated standard drills, making it suitable for general workshop, fabrication and maintenance tasks involving steel and other ferrous materials.

Advantages

The HSS M2 material offers high hardness and heat resistance for sustained cutting performance at typical drilling speeds. The black-gold coating reduces friction on the cutting lips and enhances surface durability, which helps extend tool life in regular metal drilling operations. The extended length provides better reach into deep or hard-to-access areas without requiring extensions or awkward setups. Overall design balances rigidity and flexibility to maintain hole quality in 3.2 mm diameter applications.

Suitable for

• Drilling holes in mild and medium carbon steel
• Fabrication and workshop metalworking tasks
• Maintenance and repair where extra reach is needed
• Drilling in ferrous materials requiring a 3.2 mm hole

Key specifications

• Material: High-speed steel (HSS M2)
• Diameter: 3.2 mm
• Type: Extended-length twist drill
• Coating: Black-gold surface treatment for improved wear resistance
• Intended use: Metal drilling, especially ferrous materials

How to use

Select an appropriate drilling speed and feed for HSS M2 in the material being drilled; lower speeds are recommended for harder steels. Secure the workpiece firmly and use a center punch for accurate hole starting. Apply steady, moderate pressure and allow the drill to cut without excessive force. Periodically withdraw the drill to clear chips and maintain cooling; use cutting fluid or coolant when drilling steel to reduce heat and prolong tool life. Finish by deburring the hole edges as required.

Usage recommendations

For best results, match drill speed and cutting fluid to the specific steel grade; keep feeds steady and avoid overloading the drill. Replace the bit when wear or chipping degrades hole accuracy. Store the drill in a dry place to preserve the coating.
