Drill bit Abraboro HSS cylindrical 3 mm for metal, model AB46803000

Abraboro HSS cylindrical drill bit 3 mm is designed for precise drilling in metal. Made from high-speed steel (HSS), this 3 mm bit offers wear resistance and reliable edge retention for drilling in steel, non‑ferrous metals and common alloys. Its cylindrical shank fits standard chucks for use in handheld drills and drill presses, providing a compact solution for small-diameter hole making in fabrication, maintenance and repair tasks.

Advantages

The HSS material delivers a balance of hardness and toughness that supports extended cutting life when drilling common metals. The 3 mm diameter enables precise, small-diameter holes with minimal wandering, and the cylindrical shank ensures compatibility with a wide range of drill chucks. The bit’s geometry is optimised for consistent chip evacuation and controlled heat generation during typical metalworking speeds.

Suitable for

• Drilling holes in mild and stainless steels
• Working with non‑ferrous metals such as aluminium, brass and copper
• Maintenance and repair tasks requiring small, accurate holes
• Fabrication and assembly where compact, repeatable drilling is needed

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 3 mm
• Shank type: cylindrical
• Intended application: metal drilling (steel, non‑ferrous metals, alloys)
• Compatible tools: handheld drills and drill presses with standard chucks

How to use

Select an appropriate drilling speed and feed for the workpiece material; lower speeds are advisable for harder steels and higher speeds for softer non‑ferrous metals. Secure the workpiece to prevent movement, mark the hole position, and use a centre punch if necessary to prevent walking. Fit the cylindrical 3 mm bit into the drill chuck and tighten securely. Apply steady, even pressure, withdrawing occasionally to clear chips and reduce heat build-up. Use cutting fluid when drilling steel or harder alloys to extend tool life and improve hole quality.

Usage recommendations

For best results, match drill speed and lubrication to the material: moderate speeds with cutting oil for ferrous metals and higher speeds without heavy lubrication for aluminium. Replace the bit if wear or chipping reduces hole accuracy; regrinding should be done by a qualified service to preserve correct geometry.
