Drill bit for metal Tvardy 14.00 mm HSS black-gold, model T02140, packed 1/50/100

Tvardy HSS metal drill bit, 14.00 mm diameter, black‑gold coated (model T02140) is designed for drilling steel and other metal materials. Manufactured from high‑speed steel (HSS), this drill bit provides a balance of hardness and toughness for repeated use in hand drills and drilling machines. The black‑gold surface treatment enhances wear resistance and facilitates chip evacuation, making it suitable for workshop and industrial environments. The product is available singly or in multi‑packs to suit individual or production needs.

Advantages

The HSS material delivers reliable cutting performance and retains hardness at elevated temperatures, allowing for efficient penetration of metal workpieces. The black‑gold coating reduces friction and improves durability during prolonged use, while the geometry of the cutting edges helps stable chip formation and evacuation. Compatibility with common chucks and drilling equipment makes this 14.00 mm drill bit a practical choice for general metalworking tasks.

Suitable for

• Drilling holes in mild and medium‑hard steels
• Working with non‑ferrous metals and alloys
• Maintenance and repair tasks in workshops and industrial settings
• Use in hand drills and bench or column drilling machines

Key specifications

• Material: High‑speed steel (HSS)
• Diameter: 14.00 mm
• Surface finish: Black‑gold coating for improved wear resistance
• Suitable tools: Hand drills, drill presses and drilling machines
• Packaging options: Single piece, 50‑pack, 100‑pack

How to use

Secure the drill bit firmly in the drill chuck, ensuring proper alignment and minimal runout. Select appropriate cutting speed and feed rate for the material being drilled; lower speeds are recommended for harder steels and higher speeds for softer metals. Use cutting fluid to reduce heat buildup and improve chip removal when drilling steel or alloy materials. Apply steady pressure, withdraw the bit periodically to clear chips, and finish the hole with controlled feed to maintain dimensional accuracy.

Usage recommendations

The 14.00 mm Tvardy HSS drill bit is intended for metalworking use; use appropriate personal protective equipment, secure workpieces, and follow machine safety guidelines. For prolonged tool life, maintain sharpness by regrinding according to original geometry and avoid excessive speeds without lubrication.
