Steel bits

To choose well in the Steel bits category, start by considering the intended use and the target material. You’ll find versatile sets and specialized bits. For example, you may see lots of 10 high-speed steel drill bits designed for drilling metal, wood, and plastic, with sizes ranging from 1 mm to 2 mm in some sets and variable lengths. Look for bits that come with a storage bag or case to help organize them and avoid corrosion. Also consider robustness and sharpness—essential for precise, long-lasting work.

A symmetrical tip improves chip removal and reduces wear, ensuring stable progress and more precise drilling. In this category, some sets highlight this design to minimize slipping and extend bit lifespan, especially on hard metals like steel and cast iron. A typical example is a lot that emphasizes symmetrical drilling-head design on smaller diameters, improving control and durability during repeated drilling.

For home DIY, choose versatile sets—like 10-piece lots—that work on metal, wood, and plastic and are easy to store in the included bag. For professional artisans, choose bits suited to specific sizes like 8.0 mm and lengths useful for drilling steel with precision and durability. In both cases, prefer high-speed steel bits designed for reliable performance and long tool life.

Store bits in the included case or bag to prevent oxidation and mixing different bits. After use, clean them and keep them in a clean, dry place to avoid corrosion. Avoid overloading and overheating by using speeds and pressure appropriate for the material and diameter. Careful organization and proper storage significantly improve performance and accuracy when drilling metal.

These category bits are mostly made from high-speed steel and designed to drill steel, iron, and other metals, while still working well on wood and plastic when the right bit type is used. You’ll see sets that indicate their versatility and usage on metal, wood, and plastic. Durability depends on the application and your temperature control while drilling, so adjust diameter and speed to match your specific work needs.

To choose the right diameter and length, match the planned drilling hole with the available diameters in the set. Small holes can be made with 1 mm or 2 mm bits, while heavier applications require wider diameters like 8.0 mm and useful lengths around 75 to 117 mm. Prefer sets that offer a varied range for flexibility and better precision, while helping avoid breakage.
