Set of MODECO HSS cylindrical drill bits for metal, including 12 sizes from 2 mm to 8 mm: 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7.5 and 8 mm. These drill bits are made of high-speed steel (HSS) and are designed for cutting and drilling in steel and other common metals. The set provides a range of diameters to match typical workshop, repair and fabrication requirements, compatible with handheld and bench drills that accept cylindrical-shank bits.
Advantages
High-speed steel construction offers good hardness and heat resistance for standard metal drilling tasks. The cylindrical shank design ensures secure clamping in drill chucks and straightforward interchangeability between tools. The included diameter range gives flexibility for pilot holes, clearance holes and finishing passes without the need for multiple individual purchases. The set is suitable for routine maintenance and small-scale fabrication where reliable, general-purpose metal drilling performance is required.
Suitable for
- Drilling holes in mild and medium-strength steel
- Workshop maintenance and repair tasks
- Metal fabrication and assembly work
- Pilot and clearance hole preparation for bolts and fasteners
- Use with handheld drills and drill presses

How to use
Select the appropriate diameter for the required hole and secure the cylindrical shank in a compatible drill chuck. Use a suitable cutting speed and feed for the size of the bit and the type of metal being drilled; apply cutting fluid or lubrication when drilling thicker or harder materials to reduce heat and extend tool life. Start with a pilot hole for larger diameters if needed, maintain firm, even pressure, and periodically withdraw the bit to clear chips.
Usage recommendations
For optimal performance, match drill speed to material hardness (higher speeds for softer metals, lower speeds for harder steels) and use cutting oil when drilling steel to improve chip removal and reduce wear. Inspect bits for wear or dulling before use and replace damaged bits to maintain hole quality and safety.
