VHM universal drills 15xD (Deep Hole Drills) by Nachreiner
Spiral drills with a length-to-diameter ratio greater than 5xD are typically only used for special applications. The longer the metal drills, the less suitable they are for very deep holes. However, there are custom-made solutions for specialized areas, which Nachreiner can cover with various sizes. Our 15xD VHM universal drill is designed as a deep hole drill and has a length-to-diameter ratio of 15, which is already at the upper limit of achievable dimensional accuracy. If you require lengths beyond this, we recommend discussing a custom solution with our specialists. Alternatively, you can find specialized deep hole drilling tools in our range that may better suit your requirements. For large diameters, we recommend using indexable inserts, especially when manufacturing in mass production, as they are often more cost-effective and yield higher productivity.
Universal drill 15xD and other sizes in Nachreiner tools range
In addition to our deep hole drill in the 15xD size, you will naturally find various other VHM tools for specific drilling depths in our range. When using NC machines and similar machine tools, precisely maintaining the specifications and especially the drilling depth is crucial for achieving flawless results.
The 15xD universal drill features the standard point angle of 140°, with the drill tips carefully ground. The guide lands are also at the upper range of what is technically possible with such tools. Furthermore, we have equipped the deep hole drills with cooling channels for internal cooling, allowing for even better temperature resistance, which is already high with solid carbide. It is important, when using internal cooling metal drills, that the cooling channels are precisely manufactured to ensure the drill's stability is not compromised. Additionally, both chip removal and coolant discharge must be able to flow freely from the hole without blockages of either byproducts. With Nachreiner tools, you can be confident that these requirements are fully met.
The tool life is significantly better compared to HSS or HSSE, thanks to the use of solid carbide, as is the cutting speed when working with deep hole drills. Especially for large drilling depths, the processing speed plays a crucial role in the production process and should not be underestimated. As is well known, the time factor has a significant impact on all processes in metalworking. With Nachreiner solid carbide universal drills 15xD, you have the best possible tool for this application. If your specifications differ, we will work together to find a practical alternative. Simply ask us – Nachreiner is here for you.
