Drill reamer

Carbide boring reamers from Nachreiner: Perfect surfaces in one step

In many areas of metalworking, simply drilling holes is not enough. For perfect precision, the surfaces of the holes must be absolutely smooth and free of unevenness, residues, or burrs. Examples of this include fine oil channels or cooling channels in engine manufacturing for the automotive industry, aerospace industry, as well as in chemical plants or production facilities in the pharmaceutical and food industries. Regardless of the reason for requiring high precision, it is typically achieved through post-processing with reamers, which remove unwanted byproducts in the hole after drilling. Our high-quality carbide boring reamers (solid carbide) can accomplish both tasks in a single operation, significantly reducing processing time and making machine processing of sensitive workpieces much easier.

Boring reamers from Nachreiner offer exceptional roundness accuracy

Boring reamers from our range in solid carbide with internal cooling are perfectly suited for applications where high roundness accuracy and excellent surface finish are required. Due to their solid carbide construction, our boring reamers can be used even in very hard workpieces made of stainless steel or other materials of similar hardness and strength. You can achieve a high cutting speed, similar to that of carbide spiral drills, with the solid carbide boring reamer. The 140° point angle is typical for a spiral drill. However, with the additional reaming elements, you eliminate the need for a separate reamer. We offer different sizes, with a typical size for boring reamers being the length-to-diameter ratio of 5xD, but of course, other configurations are also available. If you cannot immediately find the variant you need in our range, please contact our knowledgeable staff who can help you find the right option. If, in rare cases, there is no standard solution available from Nachreiner, it is not an unsolvable problem for us, as we can manufacture almost any cutting tools, taps, thread cutters, spiral drills, and reamers to company-specific specifications and factory standards. Such custom-made products are worthwhile under certain conditions, and we can clarify whether these conditions apply to you in a personal discussion to better understand your specific requirements.

Perfect surface finish with Nachreiner boring reamers

The fine machining of holes in metal parts requires not only care but also the right tool. Our reamers and boring reamers meet the highest expectations of our long-term customers. In addition to a perfect surface finish, adherence to precise dimensions and shapes according to the respective workpiece specification plays a crucial role. Therefore, the post-processing of holes is indispensable in many application areas.
