Drill Bit for Metal Smart HSS cylindrical 2 mm set of 10 pcs

Set of 10 Smart HSS cylindrical drill bits, 2 mm diameter, designed for drilling into various metals and metal alloys. These drill bits are made from high-speed steel (HSS) for improved hardness and heat resistance compared with standard carbon steel, and feature a straight cylindrical shank that fits standard drill chucks. The compact 2 mm size is suited to precision holes, pilot drilling and light metal fabrication where small-diameter accuracy is required.

Advantages

The HSS material offers reliable wear resistance and thermal stability during short to moderate drilling cycles in ferrous and non-ferrous metals. The cylindrical shank provides secure clamping in hand-held and bench-mounted drills, while the small 2 mm diameter enables precise positioning and minimal material removal. Supplied as a set of 10 pieces, the pack ensures quick replacement of worn tips and consistent drilling quality across multiple workpieces.

Suitable for

• Precision metal drilling and pilot hole preparation
• Electronics assembly and PCB mounting holes (thin metal parts)
• Light fabrication and sheet metal work
• Model making and small mechanical repairs

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical straight shank
• Diameter: 2 mm
• Quantity: 10 pieces per set
• Intended use: Drilling in metals and metal alloys

How to use

Secure the desired drill bit in the chuck of a hand drill or drill press, ensuring the bit is seated straight and clamped tightly. Use appropriate cutting speed and light steady feed for small-diameter bits to avoid overheating or breakage. Apply cutting fluid when drilling thicker or harder metals to reduce friction and extend bit life. After use, clean chips from the flutes and store the bits in a dry container to prevent corrosion.

Usage recommendations

For best results with 2 mm HSS bits, select moderate spindle speeds and low feed pressure; higher speeds increase heat and risk of breakage. Use cutting fluid on stainless steel and other hard alloys, and avoid excessive side loads to preserve tip geometry.
