## Summary description

Tvardy HSS M2 4.0 mm extended drill bit for metal with black-gold coating. Designed for drilling steel and other metals, this high-speed steel (HSS M2) bit offers increased wear resistance from its surface finish and extended length for deeper holes. Suitable for workshop, maintenance and metalworking applications with handheld or bench drills.

## Long description

Tvardy drill bit HSS M2 4.0 mm black-gold extended for metal is a high-speed steel cutting tool designed for drilling steel and other metallic materials. The M2 grade HSS core provides the hardness and heat resistance required for metalworking, while the black-gold surface finish increases wear resistance and reduces friction. Its extended length allows for drilling deeper holes where a standard-length bit would be insufficient, and it is suitable for use with handheld and bench drills in workshops, maintenance tasks and fabrication environments.
Advantages
The HSS M2 material combines toughness and heat resistance for consistent cutting performance in a variety of ferrous and non-ferrous metals. The black-gold surface finish improves chip evacuation, reduces galling and extends tool life under repeated use. The 4.0 mm diameter delivers precise hole size for fasteners and fittings, while the extended length supports deep-hole drilling without the need to change to specialized long-reach tooling. The bit is compatible with common drill chucks and operates effectively in both low- and moderate-speed drilling conditions.
Suitable for
 Drilling holes in steel, stainless steel and other metallic alloys
 Workshop and maintenance drilling with handheld or bench drills
 Fabrication, repair and assembly tasks requiring 4.0 mm holes
 Deep-hole drilling where additional reach is necessary
Key specifications
 Material: High-speed steel (HSS M2)
 Diameter: 4.0 mm
 Coating/finish: Black-gold surface treatment for increased wear resistance
 Length: Extended/long-reach geometry for deeper holes
 Shank type: Cylindrical shank compatible with standard drill chucks
 Application: Designed for drilling metals (ferrous and non-ferrous)
How to use
Secure the drill bit in the drill chuck, ensuring the shank is gripped tightly and runs true. Select an appropriate drilling speed for the material—typically lower speeds for harder steels and higher speeds for softer metals—and apply steady feed pressure. Use cutting fluid or suitable lubricant to reduce heat generation and prolong tool life, especially when drilling stainless steel or harder alloys. Withdraw the bit periodically to clear chips when drilling deep holes to maintain cutting efficiency and prevent clogging.
Usage recommendations
For best results when drilling steel and stainless steel, use a moderate constant feed and apply cutting oil. For deep-hole work, peck drilling (periodically retracting the bit to clear chips) is advised to avoid chip packing and overheating. Inspect the bit for wear or chipping before each use and replace when cutting performance degrades.
