Reamers

HSS reamers and machine reamers in 1/100 and H7 by Nachreiner

For a wide range of workpieces made of metal and other materials, Nachreiner offers proven HSS reamers and machine reamers. Wherever a solid carbide version is not necessary due to the lower strength of the materials, HSS reamers and machine reamers serve as a cost-effective and reliable alternative. In the catalog of our online shop, you will find a wide selection of reamers in 1/100 and H7 sizes:

Additionally, Nachreiner offers reamers for special requirements and specifications. If you cannot find the variant you need in our catalog, please contact us directly. Upon request, we can manufacture custom-made tools according to your individual factory standard or DIN with special finishes or modifications. Nachreiner also offers rivet hole reamers in addition to machine and hand reamers.

HSS reamers by Nachreiner in everyday use

Simply drilling holes with spiral drills or pilot drills is often only the first step in metalworking. For many applications, the surface finish of an untreated hole is not sufficient. For example, if you want to create perfectly rounded and smooth surfaces for small cooling channels in engines or other high-quality machines, reaming is recommended as a secondary process. If you plan to use reamers, this must be taken into account during drilling. The hole should not reach the final nominal size yet but must be slightly undersized. The use of countersinks or tapered countersinks should also be considered beforehand. If you use a tapered countersink, reaming the hole becomes easier. Depending on the application, there are also HSS reamers and machine reamers that come with a pre-angled cut—this typically eliminates the need for an additional tapered countersink. Only after using the reamer will the hole achieve the required nominal size, with a significantly higher surface quality and roundness than is possible with a simple spiral drill.

Always the right reamer for your application

Nachreiner’s selection is especially comprehensive. We aim to offer our customers as wide a range of tools as possible to cover the most important requirements with standard solutions. In addition, you can provide us with your own specifications, so we can create a custom quote for special tools based on your individual needs. Discuss with our expert advisors about special coatings to make your reamers more efficient and durable. Depending on the material being processed, our VHM (solid carbide) reamers may also be suitable for you—these may be better suited for machining high-strength metals like stainless steel and similar materials compared to the HSS or HSSE versions.
