Drill bit Tvardy HSS for metal, black-gold coated, 16.00 mm (T02160)

Tvardy HSS drill bit for metal, black-gold coated, 16.00 mm is a solid high-speed steel cutting tool designed for creating precise holes in steel and similar metals. The 16.00 mm diameter provides a straight, clean bore when used in appropriate drills and drill presses. A black-gold surface treatment enhances wear resistance and reduces friction during cutting, improving drilling consistency in workshop and industrial environments.

Advantages

The high-speed steel construction offers a balance of hardness and toughness for reliable cutting performance in metalworking. The black-gold coating reduces heat build-up and improves chip evacuation, which helps extend the service life of the drill bit under repeated use. Its standard 16.00 mm diameter ensures compatibility with common chucks and tooling, enabling stable and accurate holemaking when correctly aligned.

Suitable for

• Drilling through mild and medium-carbon steel
• Workshop and maintenance tasks with hand drills
• Use on drill presses for controlled, repeatable holes
• Metal fabrication and repair work requiring precise hole diameters

Key specifications

• Material: high-speed steel (HSS)
• Coating: black-gold surface treatment for wear resistance
• Diameter: 16.00 mm
• Tip geometry: ground for metal drilling (standard point angle for HSS bits)
• Intended use: drilling metal materials such as steel and similar alloys

How to use

Secure the workpiece and select a compatible chuck that grips a 16.00 mm shank firmly. When drilling metal, mark the hole position and, if necessary, use a center punch to prevent walking. Start at low to medium speed for larger diameters, apply steady pressure, and use cutting fluid or lubricant to reduce heat and improve chip flow. Withdraw the bit occasionally to clear chips and allow cooling. After use, clean and store the drill bit to prevent corrosion.

Usage recommendations

For best results, use appropriate cutting fluid and a drill press for consistent perpendicular holes; choose suitable rotational speed and feed to match material hardness. Inspect the cutting edges before use and replace the bit when wear or chipping affects hole quality.
