Evaluation of key product features

⚖️ Compare features with other products of your choice

This step drill bit enables you to ream or widen holes in sheet metal with diameters from 4 mm to 20 mm, giving the user maximum flexibility in a single tool. Its construction from high-quality HSS (high-speed steel) ensures optimal resistance to wear and heat, even during longer or more intensive work.

It is especially suitable for those who often have to drill precise holes of various dimensions in electrical boxes, pipes, sheet metal or thin metal plates. The stepped drill design simplifies the process, as there is no need to change different drills depending on the size of the hole - you adjust the diameter simply by pressing the drill deeper into the material. This allows for faster work without interruptions and minimal risk of slipping or damaging the workpiece.

Sliding edges and precision ground cuts ensure clean, smooth holes without burrs or cracks in the metal. The tool is compatible with most standard drilling machines. It also features reliable material removal due to the spiral geometry, which reduces the possibility of heating and extends the life of the drill.

The practical range of diameters makes the product an excellent choice for home workshops, technical schools or smaller factories where it is important to have an efficient drill bit at hand for everyday challenges - from simple assembly to more complex metal repairs.

Same summary

The Bosch HSS sheet metal peeling drill with a diameter of 4 mm to 20 mm is suitable for anyone who often or occasionally works with various metal sheets, both in the home workshop and on more demanding projects. Due to the wide diameter range, it allows flexibility in various tasks, but it makes more sense for users who really need dimensional variability when processing metal. For users who need extreme precision or work with very thick materials, we recommend additional verification of suitability according to actual needs. A special feature of this drill is the ability to quickly change the diameter without changing the tool itself, which simplifies the process and saves time.
