Drill bit set Smart for metal HSS 1.8 mm — 10 pcs

Set of 10 Smart HSS drill bits, each 1.8 mm in diameter, designed specifically for drilling metal. These high-speed steel (HSS) bits combine hardness and heat resistance to perform precise small-diameter drilling in a range of ferrous and non-ferrous metals. The set is intended for use with standard drill chucks and supports tasks that require accurate, repeatable holes with minimal wobble.

Advantages

The HSS material offers good cutting performance and thermal stability during continuous drilling operations. The 1.8 mm diameter is suitable for fine, precision work and reduces the need for pilot holes in small applications. Supplied as a set of 10, the bits provide ready replacements for repeated use and allow consistent hole sizes across multiple workpieces. Compatible with standard chucks, the bits are easy to change and suitable for hand-held and bench drills.

Suitable for

• Precision metalworking and fabrication
• Maintenance and repair tasks on machinery and equipment
• Drilling small holes in sheet metal, brass, aluminum and mild steel
• Model making and electronics chassis work

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 1.8 mm
• Quantity: 10 pieces
• Suitable for: ferrous and non-ferrous metals
• Compatibility: standard drill chucks (hand-held and bench drills)

How to use

Secure the appropriate drill bit in the drill chuck and tighten firmly. Mark and centre-punch the drilling point on the workpiece to prevent bit wandering. Use moderate speed and steady pressure when drilling small diameters; reduce speed for harder metals and increase coolant or cutting lubricant to manage heat buildup. Withdraw the bit periodically to clear chips and avoid clogging. After use, clean residue from the flutes and store the bits in their case or a dry, organized tool box.

Usage recommendations

For best results when drilling metal with 1.8 mm HSS bits, start with a centre punch, use cutting fluid on thicker or harder materials, and avoid excessive feed force. Replace bits that show significant wear or tool damage to maintain hole accuracy and extend overall tool life.
