Drill bit for metal Verto HSS cylindrical 7 mm, pack of 10 (60H084)

Verto HSS cylindrical drill bit, 7 mm diameter, pack of 10 is a set of high-speed steel drill bits designed for metalworking. Each bit features a straight cylindrical shank that fits standard drill chucks and is intended for drilling a range of ferrous and non-ferrous metals in workshop, maintenance, and fabrication environments. The set includes ten identical 7 mm bits to ensure continuity of work and quick replacement when bits wear.

Advantages

The HSS material provides good hardness and heat resistance for drilling into steel, cast iron, aluminum, and other common metals. Cylindrical shanks ensure compatibility with standard keyed and keyless chucks, and identical dimensions across the pack simplify tool management. A consistent 7 mm diameter offers repeatable hole sizes for production and repair tasks.

Suitable for

• Drilling holes in mild and hardened steels
• Fabrication and metal assembly work
• Maintenance and repair tasks in workshops
• Drilling through non-ferrous metals such as aluminum and brass

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical (straight) shank compatible with standard chucks
• Drill diameter: 7 mm
• Pack quantity: 10 identical drill bits
• Intended application: Metal drilling for ferrous and non-ferrous materials

How to use

Select an appropriate drilling speed and feed rate for the metal being worked; HSS bits typically perform well at moderate speeds with steady pressure. Secure the workpiece and clamp it to prevent movement. Fit the cylindrical shank into the drill chuck and tighten securely. Begin drilling with light pressure to establish the pilot engagement, then apply steady pressure and use cutting fluid or lubricant when drilling harder alloys or thicker sections to extend tool life and improve chip evacuation.

Usage recommendations

Use cutting oil or coolant for steel and other hard metals, replace worn bits from the pack to maintain hole quality, and inspect bits for chipping or bluntness before use.
