Bmmtools DIN 338 Series 1020 twist drills are high-quality tools made of high-grade HSS high-speed steel, featuring a cylindrical shank and rolled construction. They are designed for general machining of a wide range of materials, making them a universal solution for drilling holes, especially larger diameters, in various types of drills with a chuck up to 13 mm. These drill bits are characterised by durability and precision, making them suitable for industrial and workshop applications.
Bmmtools DIN 338 Series 1020 twist drills, made of high-speed steel (HSS), are best suited for drilling in materials such as mild and alloy steel, grey cast iron, non-ferrous metals (e.g. aluminium) and plastics. These are universal tools that are suitable for machining various metals of moderate hardness, ensuring precise and effective drilling. For very hard metals, such as stainless or alloy steel, 1020 series cobalt drill bits are often recommended.
