Abraboro HSS cylindrical drill bits for metal, 1.6 mm diameter, pack of 10 are precision cutting tools designed for drilling small, accurate holes in thin metal sheets and components. Manufactured from high-speed steel (HSS), these bits offer heat resistance and wear durability that suit light-duty industrial work, electronics chassis fabrication, and hobby or model-making tasks. The cylindrical shank fits standard drill chucks and handheld drills, enabling stable clamping and consistent hole geometry for repeated operations.
Advantages
These Abraboro HSS bits provide predictable cutting performance and extended life compared with carbon-steel alternatives thanks to the high-speed steel composition. The small 1.6 mm diameter allows for precise pilot holes and delicate work on thin metals; a pack of 10 ensures multiple replacements or use across a project without frequent reordering. The cylindrical shank design is compatible with common drill chucks for straightforward installation and reliable concentricity during drilling.
Suitable for
- Drilling small holes in thin steel, aluminum, brass, and other soft-to-medium metals
- Electronics chassis, printed circuit board mounting holes (non-plated areas), and enclosure work
- Model making, hobby projects, and precision metalworking where fine diameters are required
- Pilot holes for screws or as a starting point for larger-diameter drilling
When it may not be suitable
These 1.6 mm HSS cylindrical bits are intended for light to medium-duty work and thin metal sheets; they are not intended for drilling large-diameter holes or heavy machining of hardened steels. For thick material, stainless steels, or high-production applications, a more robust bit geometry, larger diameter, special coatings, or carbide grades may be more appropriate.
Key specifications
- Diameter: 1.6 mm
- Material: High-speed steel (HSS)
- Shank type: Cylindrical (suitable for standard drill chucks)
- Quantity per pack: 10 pieces
- Typical applications: Thin metal sheets, electronics, hobby and precision tasks
How to use
Secure the drill bit in a compatible chuck ensuring tight, concentric clamping. Mark the drilling point and, where appropriate, use a center punch to prevent bit walking on smooth metal surfaces. Use moderate spindle speed and constant feed pressure suitable for a 1.6 mm HSS bit; apply cutting fluid or light lubrication when drilling ferrous metals to reduce heat and extend tool life. Clear chips frequently and avoid excessive side force. Replace bits from the pack when cutting performance diminishes or when the point is damaged.
What to consider before purchase
- Confirm 1.6 mm diameter matches the required hole size for screws or components
- Ensure HSS material is suitable for the metals you will work with (thin, soft-to-medium metals)
- Check that your drill chuck accepts cylindrical shanks and can clamp small-diameter bits securely
- Consider whether coated or carbide bits are needed for harder materials or higher production
Usage recommendations
For best results, use a center punch on smooth metal, run at moderate speeds with light lubrication on ferrous materials, and replace bits from the pack at the first sign of dulling to maintain hole accuracy and finish.
