Drill bit set Abraboro HSS straight shank for metal Ø3.0 mm, 10 pcs (AB44003000)

Set of 10 Abraboro HSS drill bits with a straight (cylindrical) shank and 3.0 mm cutting diameter. Made from high-speed steel (HSS), this set is designed for drilling steel, non-ferrous metals and thin metal sheets. The cylindrical shank fits standard chucks on hand drills and drill presses, providing consistent concentricity for precision hole-making in metalworking and maintenance tasks.

Advantages

The high-speed steel construction offers hardness and wear resistance that support sustained cutting performance in metal. The straight shank design ensures compatibility with a wide range of drilling tools, including hand-held drills and bench drill presses. Supplied as a matched set of identical diameter bits, it simplifies selection for repetitive drilling operations and reduces the need for frequent tool changes.

Suitable for

• Drilling holes in mild and alloy steels
• Working with non-ferrous metals such as aluminium and brass
• Creating precision holes in thin metal sheets and panels
• Maintenance, repair and general metalworking tasks

Key specifications

• Cutting material: high-speed steel (HSS) for hardness and wear resistance
• Shank type: straight (cylindrical) shank for standard chucks
• Drill diameter: 3.0 mm
• Quantity: 10 pieces per set
• Intended workpiece: steel, non-ferrous metals, thin metal sheets

How to use

Secure the 3.0 mm drill bit in the chuck of a hand drill or drill press, ensuring the shank is properly tightened and the bit is aligned concentrically. Select an appropriate cutting speed and apply steady feed pressure; use lower speeds for hardened steels and higher speeds for softer non-ferrous metals. For cleaner holes and extended tool life, use cutting fluid or lubricant when drilling steel. Back the drill bit out periodically to clear chips when drilling deeper holes.

Usage recommendations

When drilling metal, start with a center punch to prevent walking and clamp the workpiece securely. Match drill speed and lubrication to the material: slower speed and cutting fluid for hardened steels; moderate speed for aluminium. Inspect bits for wear and replace when edges become blunt to maintain hole accuracy.
