Abraboro HSS Metal Drill Bit, 1mm, Cylindrical Shank, 10-piece Set

The Abraboro HSS metal drill bit set provides a reliable solution for precision drilling tasks requiring a 1mm diameter. This set includes 10 high-speed steel bits, each featuring a standard cylindrical shank compatible with most common drill chucks. Engineered for performance in metalworking, these bits ensure consistent results when creating small-diameter holes in a variety of materials.

Advantages

These drill bits are manufactured from high-speed steel, which provides excellent heat resistance and structural integrity during operation. The design facilitates efficient chip removal, preventing clogging and ensuring a smooth drilling process. Their precise geometry allows for accurate hole placement, making them a dependable choice for tasks where small-scale drilling accuracy is paramount.

Suitable for

• Drilling small-diameter holes in ferrous metals
• Working with non-ferrous metals such as aluminum or copper
• Precision model making and hobbyist projects
• Professional workshop applications requiring fine drilling

When it may not be suitable

These 1mm drill bits are not intended for drilling through hardened steel, masonry, or concrete, as the small diameter makes them prone to snapping under high-torque or high-impact conditions. They are also not suitable for use in heavy-duty hammer drills.

Key specifications

• Diameter: 1mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Quantity: 10 pieces per set

How to use

Insert the drill bit into the chuck of your power drill or drill press, ensuring it is centered and tightened securely. Before starting, mark the exact location of the hole to prevent the bit from wandering. Apply light, steady pressure and maintain a consistent speed to avoid overheating the bit. It is recommended to use a cutting fluid or lubricant when drilling into metal to extend the lifespan of the bit and improve the quality of the hole.

What to consider before purchase

• Ensure your drill chuck is compatible with a 1mm cylindrical shank
• Verify the material hardness of your workpiece
• Consider using a drill press for better stability with small-diameter bits

Usage recommendations

Always wear appropriate eye protection when drilling metal. Use a low feed rate to prevent the bit from breaking due to its small diameter.
