Drill bit Tvardy HSS for metal 13.00 mm (model T02130) black-gold coating

Tvardy HSS drill bit for metal, 13.00 mm diameter, is a straight-shank cutting tool designed for drilling through ferrous and non-ferrous metals in workshop and industrial environments. Manufactured from high-speed steel (HSS), the bit provides a balance of toughness and hardness suitable for routine metalworking tasks. A black-gold surface coating enhances wear resistance and assists chip flow during drilling operations.

Advantages

The HSS material delivers reliable cutting performance and resistance to deformation at typical drilling temperatures. The black-gold coating reduces friction and helps protect the cutting edges, extending tool life under normal operating conditions. The straight shank permits stable clamping in standard chucks and collets, while the 13.00 mm diameter offers a common size for through-holes and pilot holes in medium-thickness metal components.

Suitable for

• Drilling holes in steel and cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Workshop and industrial drilling operations
• Use with drill presses and hand-held drills with appropriate chuck capacity

Key specifications

• Material: high-speed steel (HSS)
• Tip diameter: 13.00 mm
• Shank type: straight shank
• Surface finish: black-gold coating for improved wear resistance
• Intended use: cutting/drilling metal

How to use

Secure the drill bit in a compatible chuck or collet, ensuring concentric clamping to minimize runout. Select drilling speed according to the workpiece material and bit diameter; reduce speed for harder alloys and increase for softer non-ferrous metals. Apply steady feed pressure and, where appropriate, use a cutting fluid or lubricant to reduce heat and improve chip evacuation. For through-holes, peck drilling or periodic withdrawal helps clear chips; for accurate holes, use a center punch and pilot drilling if necessary.

Usage recommendations

Use appropriate personal protective equipment and follow machine safety guidelines. Store the bit in a dry place to preserve the coating. Replace the bit when wear, chipping, or loss of cutting performance is observed to maintain hole quality and operator safety.
