Set of MODECO MN-60-911 HSS cylindrical drill bits for metal, containing nine sizes from 2 mm to 10 mm. The bits are made of high-speed steel (HSS), suitable for drilling mild and medium-carbon steels, cast iron and other ferrous materials. Cylindrical shanks allow use with standard chucks in hand drills and drill presses, providing straightforward interchangeability for workshop and maintenance tasks.
Advantages
The set covers a wide range of common diameters from 2 mm to 10 mm, reducing the need to change tools between jobs. High-speed steel construction provides a balance of hardness and toughness for metalworking, retaining cutting edge at typical drilling speeds. Cylindrical shanks fit most drill chucks and deliver stable centring; the uniform flute geometry supports efficient chip evacuation during drilling in metals.
Suitable for
- Drilling holes in steel and other ferrous metals
- General maintenance and repair work with hand drills
- Workshop and fabrication tasks using drill presses
- Creating pilot holes prior to tapping or countersinking

How to use
Select the appropriate bit diameter for the required hole size and secure the bit in the drill chuck, ensuring it is centred and tightened. Use suitable cutting speed, moderate feed pressure, and steady drilling motion when working with steel and similar metals. Apply cutting fluid or coolant to prolong bit life and improve chip removal, and withdraw the bit periodically to clear chips when drilling deeper holes. After use, clean and store the bits in their case to prevent corrosion and protect the cutting edges.
Usage recommendations
For best results when drilling metals, use lower rotational speeds for larger diameters and harder materials, maintain steady pressure without forcing the bit, and employ appropriate lubrication or cutting fluid to reduce heat and wear.
