Drill bit for metal Smart HSS cylindrical 7.5 mm set of 5 (11-075)

Smart HSS cylindrical drill bits, 7.5 mm diameter, set of 5 pieces designed for drilling metal. These high-speed steel bits are intended for use in both handheld and stationary drills and are suitable for working with steel and a range of ferrous and non-ferrous metals. The cylindrical shank provides a secure fit in standard drill chucks and the HSS material offers good wear resistance and cutting performance for general metalworking tasks.

Advantages

The HSS construction ensures a balance of hardness and toughness for consistent drilling performance and longer tool life under normal workshop conditions. A uniform 7.5 mm diameter across the set allows quick replacement and consistent hole sizes. The cylindrical shank fits conventional chucks without adapters, enabling straightforward use in repair, fabrication and maintenance tasks.

Suitable for

• Drilling steel sheets and plates
• Working with non-ferrous metals such as aluminum and brass
• General workshop repairs and maintenance
• Metal fabrication and prototyping
• Use in handheld and bench drills

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Diameter: 7.5 mm
• Quantity in set: 5 pieces
• Intended materials: Ferrous and non-ferrous metals

How to use

Select an appropriate drilling speed and clamp the workpiece securely before drilling. Install the 7.5 mm cylindrical shank into the drill chuck and tighten firmly. For thicker or harder metals, use cutting fluid to reduce heat and improve tool life. Apply steady, moderate pressure and allow the drill bit to cut rather than forcing it; withdraw periodically to clear chips for improved cooling and hole quality.

Usage recommendations

For best results, match drill speed to material hardness, use appropriate coolant when drilling harder steels, and replace bits when signs of wear such as chipping or poor cutting performance appear. Store the set in a dry place to avoid corrosion and inspect shank and tip before each use.
