You have everything ready, clamped the workpiece in place, clamped the drill, but it's still not working. Your hole isn't straight, the material is fraying, or the drill starts smoking after a few seconds. There's probably something wrong with the twist drill, which can be quite time-consuming and costly to fix.

On Saturday, November 15, 2025, RUKO welcomed a total of 17 influencers to its production site in Holzgerlingen. The specialists, who came from Germany, Austria, and, for the first time, England, with a focus on crafts, industry, and technology, were treated to an exciting mix of RUKO insights, extensive product testing opportunities, and, of course, plenty of room for networking and exchange at the third annual Tool Xpert Day.

Not all twist drills are the same. It is not only the material (e.g., HSS or carbide) that is decisive, but above all the manufacturing process—ground or rolled. What exactly does that mean? And which drill is suitable for which application?

The shortage of skilled workers poses major challenges for a wide range of industries – including in the Böblingen and Tübingen region. RUKO GmbH Präzisionswerkzeuge from Holzgerlingen addressed this issue in spring 2025 with a regionally focused recruitment campaign. The aim was to raise the company's profile as an attractive employer while appealing to a variety of target groups: from trainees, interns, and dual students to skilled workers and administrative staff for areas such as manufacturing, warehousing, logistics, and sales.

When selecting drills, countersinks, or milling cutters, many people initially focus on the material, length, or tip angle. However, one detail is just as important: the shank. It influences power transmission, grip, concentricity, and ultimately the machining result.

This article provides an overview of the most common tool shanks and their areas of application. We also show you where their strengths lie and when you need which one.
