Drill bit for metal Smart 8.0 mm HSS, set of 5

Drill bit for metal Smart 8.0 mm HSS, set of 5 is a set of five high‑speed steel twist drill bits designed for drilling and enlarging holes in steel, non‑ferrous metals and other common metalwork materials. Each bit has an 8.0 mm diameter and a standard shank designed to fit conventional drill chucks, making the set suitable for hand drills and drill presses used in workshops, construction sites and repair jobs that require accurate metal drilling.

Advantages

The HSS material provides good hardness and heat resistance for sustained drilling in metal, while the uniformly ground twist geometry ensures efficient chip removal and stable cutting action. Supplied as a set of five, the kit reduces downtime from bit wear and provides spares for repetitive tasks. The standard shank diameter offers broad compatibility with common drill chucks and quick mounting for both portable and stationary drilling equipment.

Suitable for

• Drilling holes in steel sheets, plates and structural components
• Working with non‑ferrous metals such as aluminium, brass and copper
• Maintenance, repair and retrofit tasks in workshops and on-site
• Preparing holes for tapping or larger diameter reaming

Key specifications

• Material: high‑speed steel (HSS)
• Diameter: 8.0 mm
• Number of pieces: 5
• Tip style: standard twist point suitable for metal
• Shank type: straight round shank for standard chucks

How to use

Secure the appropriate drill bit in the drill chuck and tighten firmly. Mark the drilling position and, if needed, spot‑drill a small pilot hole to improve accuracy. Use cutting fluid or lubricant when drilling steel to reduce heat and extend tool life. Apply steady, moderate pressure and maintain appropriate spindle speed for metal drilling; withdraw the bit occasionally to clear chips. After use, clean chips from flutes and store the bits in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling hard or thick metal, start with a pilot drill and use a suitable cutting lubricant. Match drill speed to the material: lower speeds for harder steels, higher speeds for softer non‑ferrous metals. Inspect bits for wear or chipping and replace if cutting performance decreases.
