HSS step drills: Quality that impresses
Our HSS step drills are specially designed for use in metal and other hard materials. They are characterised by their ability to produce precise holes with smooth edges, which is particularly important in metalworking. The high heat resistance of HSS ensures a long service life and minimises wear during the drilling process.
Perfect drilling in various diameters without changing tools
We offer step drills in various diameters and steps to meet the different requirements of our customers. Whether you need small through holes or larger holes, we have the right step drill for you. Our range includes diameters from 4 mm to an impressive 32 mm. The different steps allow you to achieve the exact hole sizes you require. A step drill can be used to drill a variety of hole sizes, eliminating the need to change tools. The precisely defined drilling steps also create an exact transition between diameters, an indispensable feature for applications that rely on millimetre-precise results.
Robust materials and coatings for maximum durability
RUKO relies on durable materials and modern coatings to meet the high demands of professional users. The step drills are equipped with high-quality titanium or even the special RUnaTEC coating. This nano technology offers extreme heat resistance and enables a higher cutting speed, which is particularly advantageous when machining stainless steels and other resistant metals. The service life of the step drills is significantly increased and heat generation during drilling is reduced - an important aspect in order to avoid deformation of the workpiece.
Technological innovation: RUKO's FLOWSTEP® technology and RUnaTEC coatings
The step drills are characterised by their technological innovations. The FLOWSTEP® tip ensures precise and clean drill holes, while the RUnaTEC coating guarantees a longer service life and higher performance. Thanks to the FLOWSTEP® tip, precise centring is possible without centre punching. This combination makes RUKO step drills an indispensable tool in any professional workshop.
Secure hold and easy handling
Another highlight of the RUKO step drills is the sophisticated shank design, which ensures a secure hold in the drill chuck. The spiral flutes of the step drills have been specially developed to ensure optimum chip removal and prevent jamming. This enables even, low-vibration drilling, which increases work safety and makes the tool easier to handle. The precise workmanship and ergonomic design make RUKO step drills a reliable tool for professional use.
Variety and adaptability: The right step drill for every requirement
RUKO offers a wide range of step drills, including variants in HSS (high-performance steel), HSS-TiN (titanium nitride coating) and HSS-TiAlN (titanium aluminium nitride coating). They are ideal for materials such as sheet steel, aluminium, plastic or stainless steel and offer a reliable solution for a wide range of applications - RUKO has the right step drill bit for every requirement in its range.
FAQs step drills
A step drill is a cylindrical drilling tool with several successive steps or stages. Each step has a larger diameter than the previous one, which makes it possible to produce different hole sizes in a single drilling operation. This saves time and reduces the need to use different drills.
The use of a step drill offers a number of advantages:
-
Efficiency: Step drills can perform several drilling steps in one pass, which saves time and effort.
-
Precision: They enable precise drilling with smooth edges.
-
Versatility: Step drills are suitable for various materials such as metal, plastic and wood.
- Space saving: By reducing the number of drill bits required, you save space in your toolbox.
The combination of innovative technologies such as FLOWSTEP® and RUnaTEC coatings, together with the variety of models on offer, make RUKO step drills unique. They offer unrivalled quality and durability.
RUKO step drills are versatile and are particularly suitable for demanding tasks in metalworking, automotive workshops, electrical installation and other areas where precision and clean holes are required.
Choosing the right step drill depends on the materials and requirements of the project. RUKO offers a wide range of step drills for different applications so that the right drill is available for every project.
The RUnaTEC coating increases the hardness and wear resistance of the drill bit, resulting in a longer service life and consistently high performance, even under difficult conditions.
RUKO step drills are made from high-quality HSS and retain their sharpness for a long time. However, if resharpening is required, we recommend using a special drill sharpener or contacting a professional tool service. This will maintain the sharpness and performance of your step drill.
Yes, step drills can be used in most commercially available drills. Make sure that your drill has the required speed and power for the respective step drill. This will enable you to drill efficiently and precisely.
