Customized drinks at the touch of a button - what sounds like a dream of the future is already a reality at the University of Stuttgart.
The innovative MADRID dispensing system is not only the result of creative engineering work, but also a key challenge: precise production with high material requirements.
This is precisely where high-performance tools such as RUKO's solutions come into play.
Anyone who works with sheet metal regularly is familiar with the problem: with a conventional twist drill, it is often difficult to drill clean holes in thin sheet metal – especially in aluminum or steel. The drill hole can tear out, the diameter becomes inaccurate, or the edges have to be laboriously deburred afterwards.
However, precise holes and clean hole edges are crucial in metalworking. That is why many professionals use special tools such as step drills or sheet drills.
Both tools are designed for thin sheet metal (up to 4 mm material thickness, depending on the material) and similar materials and enable precise drilling, often even without pre-drilling. Nevertheless, they differ significantly in terms of design, function, and area of application.
In this article, we highlight the most important differences and explain when a step drill and when a sheet drill is the better choice.
If you work with drilling, milling or countersinking tools regularly, you have probably heard of HSS-Co 5 or HSS-Co 8. But what exactly is the meaning behind the terms? And why do so many professionals swear by these materials?
In this article we will explain what HSS-Co 5 and HSS-Co 8 are and when it really makes sense to use them.
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.
