## Summary description

Tvardy extended drill bit made of HSS M2 with a 5.5 mm diameter, black‑gold coated for drilling metal. Designed for cutting and machining steel and other ferrous materials, the extended length provides deeper reach and access in tight or recessed areas. Suitable for workshop, maintenance, and industrial metalworking tasks requiring durable high‑speed steel performance.

## Long description

Tvardy HSS M2 5.5 mm black-gold extended drill bit is a high-speed steel cutting tool engineered for drilling metal. The 5.5 mm diameter delivers a precise hole size while the extended length allows access to recessed or deep locations in workpieces. The black-gold coating improves surface hardness and reduces friction, supporting consistent performance on steel and other ferrous materials in workshop, maintenance, and industrial settings.
Advantages
The HSS M2 material provides elevated heat resistance and wear tolerance compared with standard carbon-steel bits, enabling sustained cutting speed and longer tool life. The extended length offers greater reach without compromising rigidity for typical metal drilling tasks. The black-gold surface treatment decreases adhesion of chips and improves lubricant retention, which can reduce heat buildup and improve hole finish. The 5.5 mm diameter is suitable for creating clearance or pilot holes that require accurate sizing.
Suitable for
Drilling through steel, cast iron and other ferrous metals
Accessing deep or recessed holes in assemblies and panels
Workshop repairs, maintenance and fabrication tasks
Use with hand-held drills and drill presses where extended reach is required
Key specifications
Material: high-speed steel M2
Diameter: 5.5 mm
Finish: black-gold coated surface
Type: extended length drill bit for metal
Tip geometry: designed for metal cutting (split or standard point depending on production batch)
How to use
Secure the workpiece and select an appropriate cutting speed for HSS on ferrous materials; use coolant or cutting fluid to control temperature and prolong bit life. Clamp the bit firmly in the drill chuck and center before starting. Apply steady feed pressure; avoid excessive force that can cause bit deflection or breakage. For deep holes, retract periodically to clear chips and maintain coolant flow. After use, clean the bit and store it in a dry place to avoid corrosion.
Usage recommendations
For best results when drilling steel, use moderate spindle speeds and steady feed, apply cutting fluid, and retract occasionally to clear chips. Replace the bit when wear or chipping affects hole quality.
