Drill bit set Abraboro HSS cylindrical metal 2 mm, 10 pcs (AB00010201)

Abraboro HSS cylindrical drill bit set for metal, 2 mm diameter, 10 pieces provides a compact selection of small-diameter high-speed steel drills designed for metalworking. Each drill in the set has a 2 mm cutting diameter and a cylindrical (straight) shank that fits standard three-jaw chucks and collets. The set is intended for use where precise, repeatable holes in steel and non-ferrous metals are required, offering consistent cutting performance for workshop, maintenance and fabrication tasks.

Advantages

The high-speed steel (HSS) composition ensures good hardness and heat resistance for drilling in steel and softer metals. The cylindrical shank simplifies mounting in common drill chucks and portable drills. Supplied as a set of 10 identical 2 mm drills, it supports repetitive work and quick replacement of worn tools. The small diameter and precise manufacturing contribute to clean hole quality and controlled chip evacuation when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in mild and alloy steels
• Drilling non-ferrous metals such as aluminium, copper and brass
• Workshop repairs, maintenance and equipment assembly
• Model making, electronics enclosures and precise metal fabrication

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 2 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Quantity in set: 10 pieces
• Intended use: drilling in steel and non-ferrous metals

How to use

Secure the appropriate drill firmly in the chuck of a portable drill or drill press. Select cutting speed suitable for 2 mm HSS drills and the workpiece material — higher speeds for non-ferrous metals and lower speeds for harder steels. Use a center punch to mark hole positions for accuracy, and apply cutting fluid or light oil when drilling steel to reduce heat and extend tool life. Feed the drill with steady, even pressure, retracting periodically if chips accumulate to clear the hole and improve cooling.

Usage recommendations

For optimal results, start holes with a pilot or center mark, use appropriate cutting lubricant for ferrous materials, and match drill speed to material hardness. Replace drills from the set when wear causes poor hole quality; re-sharpening small-diameter HSS drills may be possible with suitable grinding equipment.
