Drill bit Tvardy HSS for metal 10.00 mm, black-gold coating, MPN T02100

Tvardy HSS drill bit for metal, 10.00 mm diameter, features a black‑gold coating and is made from high‑speed steel. It is intended for drilling steel and other ferrous metals with hand drills and drill presses. The HSS material provides elevated hardness and heat resistance during cutting operations, while the surface coating reduces friction and helps extend tool life during repetitive metalworking tasks.

Advantages

The high‑speed steel construction offers good hardness and temperature stability for drilling into a range of ferrous materials. The black‑gold coating lowers cutting resistance and improves wear resistance, leading to longer service life and more consistent hole quality. Accurate 10.00 mm diameter and a standard flute geometry support efficient chip evacuation and stable drilling performance in both portable and stationary drilling equipment.

Suitable for

• Drilling through carbon steel and alloy steel
• General metal fabrication and workshop tasks
• Maintenance, repair and installation work requiring round holes
• Use with hand drills and drill presses

Key specifications

• Material: high‑speed steel (HSS)
• Diameter: 10.00 mm
• Coating: black‑gold surface finish
• Intended materials: steel and other ferrous metals
• Shank type: straight cylindrical shank for standard chucks

How to use

Secure the drill bit in the drill chuck and ensure it is clamped straight and firmly. Mark the drilling position and, if needed, use a center punch to prevent walking. Select a suitable cutting speed for the material being drilled—lower speeds for harder steels and higher speeds for softer ferrous materials—and apply steady feed pressure without forcing the bit. Use cutting fluid or coolant when drilling thicker sections or harder alloys to reduce heat buildup and extend tool life. Retract periodically to clear chips if drilling deep holes.

Usage recommendations

For best results, match the drill speed and feed to the specific steel grade, keep the bit adequately cooled with cutting fluid on continuous cuts, and replace the bit when wear or loss of cutting edge affects hole quality.
