Drill bit set Proline 76072 HSS 7.2 mm, 10 pcs

Set of 10 Proline HSS drill bits with a 7.2 mm diameter designed for general-purpose drilling in metal, wood and plastics. The bits are made from high-speed steel (HSS) to provide improved wear resistance and maintain cutting performance during repetitive use. The compact set includes ten identical bits and a simple storage case for easy replacement and consistent hole size when working with hand drills or drill presses.

Advantages

High-speed steel construction ensures a balanced combination of hardness and toughness for longer tool life under normal working conditions. The 7.2 mm diameter is suitable for common fastening and clearance hole applications. The uniform set of ten bits simplifies logistics on the job or in a home workshop by providing immediate spares to reduce downtime. The compact case protects the cutting edges and facilitates neat storage.

Suitable for

• Drilling through mild steel and non-ferrous metals
• Creating holes in hardwoods, softwoods and engineered wood
• Drilling holes in plastics and composite materials
• Use with corded or cordless hand drills and drill presses
• Repair, maintenance and DIY projects requiring consistent 7.2 mm holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 7.2 mm
• Quantity: 10 pieces
• Suitable tool types: hand drills, cordless drills, drill presses
• Typical applications: metal, wood, plastic

How to use

Select the appropriate drill speed and clamping method for the workpiece material. Secure the workpiece and mark the drilling position. Fit the 7.2 mm HSS bit into the drill chuck and tighten according to the drill manufacturer’s instructions. Begin drilling at a moderate speed with steady pressure, periodically withdrawing the bit to clear chips when drilling metal or deep holes. Use cutting fluid for extended life and cooler operation when working with metals. After use, allow the bit to cool, clean debris from the flutes and return bits to the storage case.

Usage recommendations

For best results when drilling metal, use appropriate cutting fluid and moderate speeds; for wood and plastics, higher speeds and reduced pressure can improve chip evacuation and hole quality. Inspect bits regularly for bluntness or damage and replace when performance degrades to avoid damaging the workpiece or the tool.
