Drill bit set Smart HSS for metal 1.0 mm, 10 pieces

Set of 10 Smart HSS drill bits with a 1.0 mm cutting diameter, intended for precision drilling in metal. Made from high-speed steel (HSS), these bits combine hardness and heat resistance to maintain cutting performance during metalworking. Compatible with handheld drills and drill presses, the set is designed for creating small, accurate holes in steel, aluminum and other ferrous and non-ferrous metals used in workshop, repair and light fabrication tasks.

Advantages

The HSS material provides good wear resistance and retains hardness at elevated temperatures, which helps reduce bit dulling when drilling metal. A uniform 1.0 mm diameter across the set ensures consistent hole size for repeated tasks. The small diameter and rigid construction enable precise positioning and clean entry points, while compatibility with common drill chucks allows use in both portable and benchtop drilling equipment.

Suitable for

• Drilling small-diameter holes in steel components
• Creating pilot holes in aluminum and non-ferrous metals
• Precision work in metal repair and maintenance
• Model making, electronics chassis and sheet metal tasks

Key specifications

• Quantity: 10 pieces
• Cutting diameter: 1.0 mm
• Material: High-speed steel (HSS)
• Intended use: Metal drilling (ferrous and non-ferrous)
• Compatible equipment: Handheld drills and drill presses with standard chucks

How to use

Select the appropriate drill speed and clamp the workpiece securely to prevent movement. Install a 1.0 mm HSS bit in the drill chuck and ensure it is tightened correctly. For best results when drilling metal, use steady, moderate feed pressure and a suitable cutting lubricant or coolant to reduce heat and prolong bit life. Back the bit out periodically to clear chips when drilling deeper holes, and allow the bit to cool if it becomes noticeably hot.

Usage recommendations

Use low to moderate rotational speeds for small-diameter metal drilling and apply cutting fluid when working with harder alloys. For increased accuracy, pilot or center-mark the drilling point and use a drill press where possible. Store the bits in a protective case to prevent tip damage and corrosion.
