Set of MODECO HSS drill bits for metal with cylindrical shanks, covering diameters from 1.5 mm to 6.5 mm. The assortment includes commonly used small and medium sizes (1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, 6.5 mm), manufactured from high-speed steel to provide hardness and resistance to wear during cutting of steel, non-ferrous metals and sheet metal. The cylindrical shank design ensures compatibility with standard drill chucks used in bench and handheld drills, making this set suitable for workshop, maintenance and DIY use where precise hole making is required.
Advantages
The HSS material offers a balance of hardness and toughness for drilling into various metals while resisting rapid wear at typical operating speeds. A wide range of diameters in one kit reduces the need to switch between multiple individual bits and allows quick selection of the appropriate size for different tasks. Cylindrical shanks provide secure seating in standard chucks and simplify bit changes. The set is compact and organized for storage and easy transport between job sites or within a workshop.
Suitable for
- Drilling holes in mild and alloy steels
- Work on non-ferrous metals such as aluminium, brass or copper
- Piercing and enlarging holes in sheet metal and thin plates
- General workshop, maintenance and DIY tasks requiring precision holes

How to use
Select the drill bit with the required diameter from the set and insert the cylindrical shank into the drill chuck, ensuring it is tightened securely. Mark the drilling point and, when working on metal, use a center punch to prevent bit wandering. Start drilling at a low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady pressure without forcing the bit; use cutting fluid or oil when drilling thicker or harder metals to reduce heat and extend bit life. After use, clear chips from the flutes and store the bit in its case.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves, when drilling. Match drill speed and feed to the material and bit diameter, and use cutting fluid for improved tool life and hole quality when working with steel or thicker sections. Regularly inspect bits for wear or chipping and replace damaged bits to maintain drilling accuracy and safety.
