by Bernard Martin  For metalcutting professionals achieving precision in small bore machining has always been a challenge. The Dümmel Ultramini tool-line is designed to meet this challenge head-on, offering an unparalleled solution for turning the smallest bores with ease and precision. This article is going to explain some of the unique features of the Dümmel Ultramini and compare it to some of the other competitors products in the market. Why Choose the Dümmel Ultramini? The Dümmel Ultramini tool-line stands out for several key reasons, making it a great choice for small bore machining. First, the sharp cutting edges of Ultramini tools result in extended tool life, reducing the need for frequent replacements and minimizing downtime. The special cooling channel ensures a stable and eccentric shank part, enhancing overall performance and durability. Some sizes within the Ultramini range offer a superior length-to-diameter ratio when compared to competitors such as P.H. Horn, Simtek, and Gühring, making the Dümmel Ultramini ideal for deeper and more precise cuts. Generally, toolholders for the Ultramini are less expensive compared to those of other brands, offering a more economical solution without compromising on quality. We'll dig into to some of those details below as well. In the U.S., through their exclusive collaboration with Everede Tool, Dümmel stocks G holders with a precision of 0.0004", compared to the 0.0008" precision of competitors. With over 1,000 different standard inserts, the Ultramini line boasts one of the largest standard product ranges available, ensuring that you can find the perfect tool for your specific needs. The Ultramini range includes a variety of inch-size threading and grooving tools, catering to the diverse needs of the industry. Lastly, the innovative clamping system, with the clamping flat positioned on top of the insert’s shank, ensures a secure and precise hold during operation. Competitive ComparisonWhen compared to major US competitors, with P.H. Horn, Simtek and Guhring, the Dümmel Ultramini tool-line offers distinct advantages over several competitors. Below is breakdown of how Ultramini competes. Compatibility with ISCAR PiccoCut Jet Line Before we take a deep dive into the competitors products let's talk about compatibility. A key advantage of the Dümmel Ultramini tools is their compatibility with ISCAR PiccoCut Jet Line holders. This compatibility ensures that customers can seamlessly integrate Dümmel tools into their existing setups, maximizing their investment and operational efficiency.  The Dümmel Ultramini uses two set screws to secure the insert. Dümmel vs P.H. Horn The Dümmel Ultramini coupling system offers a distinct advantage over the P.H. Horn coupling system in terms of the number of set screws and the clamping method. The Dümmel Ultramini uses two set screws to secure the insert. These set screws clamp onto a flat ground surface on the insert’s shank, ensuring a secure and precise hold. This design provides stability and reduces the likelihood of insert movement during operation, resulting in more accurate machining and longer tool life. In contrast, the P.H. Horn coupling system uses a different clamping method. It typically relies on a single set screw that clamps onto the radius of the carbide bar. This method is less stable compared to the Dümmel system because clamping onto the radius can allow for slight movements and misalignments, which can impact the precision of the machining process and potentially lead to quicker wear and tear of the tool. The key differences between the two systems highlight the superior design and functionality of the Dümmel Ultramini coupling system, making it a more reliable choice for small bore machining.  Ultramini Grooving, boring and profiling starting at Ø 0.2 mm Dümmel vs Simtek When comparing Dümmel Ultramini to Simtek, although both offer similar quality and sharp inserts, Dümmel distinguishes itself through several specific engineering advantages and tighter tolerances, as well as the economics of its toolholders and a broader product range. The Dümmel Ultramini toolholders are designed to be more economical without sacrificing quality. The toolholders are simpler and less expansive to manufacture, yet they maintain very high precision. This cost-effective design results in significant savings for users while ensuring reliable performance. Dümmel's toolholders are also engineered with tighter tolerances. For example, the G holders available in the USA have a precision of .0004", compared to Simtek's typical .0008". This tighter tolerance means that Dümmel tools fit more precisely, reducing vibration and improving the accuracy of the machining process. This precision is critical in small bore machining, where even slight deviations can significantly impact the quality of the final product. The Dümmel Ultramini range offers a broader product selection. With over 1,000 different standard inserts, Dümmel provides a comprehensive array of tools to meet diverse machining needs. This extensive range ensures that users can find the ideal tool for their specific applications, whether it involves threading, grooving, or other specialized operations. In contrast, while Simtek has a robust product line, it does not yet seem to match the sheer variety and availability that Dümmel offers. In summary, the combination of economical toolholders, tighter engineering tolerances, and a wider product range gives Dümmel Ultramini a distinct edge over Simtek in small bore machining Dümmel vs Guhring When comparing Dümmel Ultramini tools to Gühring’s offerings, Dümmel stands out for several reasons. Dümmel Ultramini inserts have exceptionally sharp cutting edges, essential for precision in small bore machining. These sharp edges reduce cutting forces, minimize tool wear, and improve surface finish. In contrast, Gühring’s inserts are not as sharp, leading to higher cutting forces and increased wear over time, which can compromise machining quality. Dümmel’s sharper inserts also contribute to longer tool life and better performance by creating less friction and heat during cutting, reducing the likelihood of tool degradation. This results in more consistent performance and fewer tool changes. Gühring’s inserts, being less sharp, may require more frequent replacements and can interrupt the machining process. Dümmel Ultramini tools are designed with tighter tolerances, ensuring a precise fit and stability during machining. This precision is crucial for small bore applications, where minor deviations can significantly impact the final product. Gühring’s inserts, while precise, do not match Dümmel’s level of tight tolerance and stability, affecting machining accuracy. Dümmel Ultramini tools offer sharper inserts, better performance, higher precision, enhanced cooling and stability, and a more targeted product range compared to Gühring, making Dümmel a superior choice for small bore machining applications. Additionally, Dümmel Ultramini tools feature a special cooling channel that enhances stability and prevents overheating, maintaining sharpness and performance even during extended use. Gühring’s tools, although effective, lack the same level of innovation in cooling and stability, which can affect performance in high-demand applications. While Gühring offers a large product range, Dümmel Ultramini provides a more specific and varied selection for small bore machining. Dümmel’s comprehensive range of inserts and toolholders ensures users can find the ideal tools for their needs, whereas Gühring’s broader range may not be as finely tuned to this niche market. Limited Time Promotion! To further entice customers, Dümmel is offering a toolholder swap promotion. Customers can exchange their Horn Supermini and Sandvik CXS toolholders for Dümmel toolholders on a one-for-one basis, regardless of quantity.
