Drill bit Tvardy HSS for metal 9.50 mm, black-gold coating (MPN T02095)

Tvardy HSS drill bit for metal, diameter 9.50 mm, features a high-speed steel core and a distinctive black-and-gold coating. Designed for cutting and drilling steel and other metal materials, this drill bit is compatible with hand drills and drill presses used in workshops, maintenance tasks, and industrial environments. The geometry and material selection aim to maintain cutting performance during repeated use while the surface treatment reduces friction and improves wear resistance.

Advantages

The high-speed steel (HSS) construction provides reliable hardness and toughness for metal drilling applications. The black-and-gold coating enhances surface durability and lowers heat build-up at the cutting edge, which can extend tool life and improve drilling consistency. The 9.50 mm diameter offers a standardized size for through-holes and pilot operations in medium-thickness metal sheets and components. The bit is compatible with common tooling holders and chucks for straightforward installation and removal.

Suitable for

• Drilling holes in mild and alloy steels
• Workshop and maintenance drilling tasks
• Use with hand-held drills and drill presses
• Fabrication and light industrial metalworking

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 9.50 mm
• Surface finish: black-and-gold coating for reduced friction and increased wear resistance
• Designed application: metal drilling
• Compatible tools: hand drills and drill presses

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring it is centered and tightened. Mark and clamp the workpiece to prevent movement. Start drilling at a low speed to establish the cut, then increase speed according to material thickness and drill stability. Apply steady pressure without forcing the bit, and clear chips periodically to avoid clogging and overheating. Use cutting fluid or lubricant for steel and harder alloys to improve chip evacuation and reduce wear.

Usage recommendations

For best results, select an appropriate cutting speed and use coolant or cutting oil when drilling thicker or harder metals. Inspect the drill bit for wear before use and replace it when cutting performance declines to maintain hole quality and operator safety.
