Drill bit Verto HSS cylindrical 5 mm, set of 10 (model 60H080.)

Verto HSS cylindrical drill bit, 5 mm diameter, in a set of 10 is a compact selection of high-speed steel bits designed for repeated drilling of precise 5 mm holes. The bits feature a straight cylindrical shank for use in standard drill chucks and are intended primarily for cutting through metal and other hard materials where durability and cutting-edge retention are important.

Advantages

The high-speed steel construction offers improved heat resistance and wear life compared with ordinary carbon-steel bits, maintaining cutting performance during extended use. The cylindrical shank ensures secure clamping in common chucks and straightforward replacement. Supplied as a set of ten identical 5 mm bits, the package reduces downtime by providing ready spares for workshop and maintenance tasks.

Suitable for

• Drilling through mild steel and other ferrous materials
• Metalworking and fabrication workshops
• General maintenance and repair tasks
• Drilling in hard plastics and some non-ferrous metals
• Production runs that require multiple identical holes

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight cylindrical
• Cutting diameter: 5 mm
• Quantity in set: 10 pieces
• Intended use: drilling in metal and hard materials

How to use

Install the 5 mm HSS bit into a standard drill chuck and tighten securely. Select an appropriate rotational speed for metal drilling—typically moderate to high depending on material hardness—and apply steady, controlled feed pressure. Use cutting fluid or coolant when drilling ferrous metals to reduce heat buildup and extend bit life. Withdraw the bit periodically to clear chips from the hole and avoid clogging.

Usage recommendations

For best results when drilling metals, use a compatible cutting oil, run the drill at the recommended speed for HSS bits, and replace the bit from the set when signs of wear or dulling appear to maintain hole accuracy and surface finish.
