Drill bit set Abraboro HSS straight shank for metal Ø6.2 mm, 10 pcs

Abraboro HSS drill bit set for metal, straight shank Ø6.2 mm contains ten identical high-speed steel bits designed for general metal drilling. The bits feature a cylindrical (straight) shank that fits standard drill chucks and holders, and an HSS composition that provides hardness and heat resistance for cutting steel and other ferrous and non‑ferrous metals. This set is intended for workshop, maintenance and fabrication tasks where reliable performance and consistent hole diameter are required.

Advantages

The HSS material ensures wear resistance and retention of cutting edge under elevated temperatures encountered in metal drilling. A straight shank offers compatibility with a wide range of hand drills and drill presses, while the uniform Ø6.2 mm diameter across all ten pieces supports repeated, consistent drilling without size variation. The set reduces downtime by providing multiple replacements and simplifies inventory for common drilling operations.

Suitable for

• Drilling through mild and medium‑hard steels
• General metal fabrication and assembly
• Maintenance and repair tasks in workshops
• Use with standard chucks on hand drills and drill presses

Key specifications

• Material: high‑speed steel (HSS)
• Shank type: straight / cylindrical
• Drill diameter: 6.2 mm
• Quantity: 10 pieces per set
• Application: metal drilling (ferrous and non‑ferrous)

How to use

Select a drill chuck or holder compatible with a 6.2 mm straight shank and secure the bit firmly to minimize runout. Use appropriate cutting fluid or lubricant when drilling steel to reduce heat buildup and extend bit life. Start at low speed to establish the hole, then apply steady feed pressure; increase speed moderately for lighter metals while reducing speed for harder steels. After use, clean and store the bits in a dry place to prevent corrosion.

Usage recommendations

For best results, use a center punch to mark pilot points on metal surfaces and clamp workpieces securely. Maintain sharpness by avoiding excessive speed and feed; replace bits from the set as soon as performance declines to ensure consistent hole quality.
