Drill bit set Verto HSS cylindrical for metal 9 mm, 5 pieces (60H088.)

Verto HSS cylindrical drill bit set for metal contains five 9 mm high-speed steel bits designed for general metalworking. Each bit has a cylindrical shank and standard point geometry suitable for use in handheld drills and drill presses. These HSS bits are intended for drilling steel, iron and other ferrous metals in workshop, service and maintenance environments.

Advantages

The high-speed steel construction provides heat resistance and wear performance appropriate for drilling into ferrous metals. A cylindrical shank ensures secure clamping in standard drill chucks. Standard point geometry delivers reliable centering and straight penetration for routine metal drilling tasks, and the matched set of five bits offers quick replacement and consistent hole diameters across multiple operations.

Suitable for

• Drilling through steel plates and profiles
• Routine maintenance and repair work on metal components
• Workshop fabrication and assembly tasks
• Use in handheld electric drills and bench drill presses
• Pilot and clearance holes in ferrous materials

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank
• Drill diameter: 9 mm
• Quantity: 5 pieces per set
• Intended materials: Steel, iron and other ferrous metals
• Geometry: Standard twist drill point

How to use

Select an appropriate cutting speed and use cutting fluid when drilling thicker or hard ferrous materials to reduce heat build-up and prolong bit life. Secure the workpiece and clamp the drill bit firmly in the chuck. Start drilling at low speed to establish the hole, then increase speed as required, applying steady pressure. Retract occasionally to clear chips and avoid clogging. Replace bits from the set when wear or chipping affects hole quality.

Usage recommendations

For best results when drilling steel or iron, use a suitable lubricant or cutting oil, maintain moderate feed pressure, and avoid excessive speeds that can overheat HSS bits. Store the set in a dry place and inspect bits for wear before use.
