Do you have Drill Reamers that are in the region of Ø70mm and/or Ø120mm that can produce a surface finish of H7?

Hi Andy,

The largest drill reamers we carry are Ø20mm: https://sphinx-tools.ch/en/catalog-products-eshop/drilling-and-reaming?st_durchmesser_conf=827

I spoke to one of our product specialists who said that at those diameters, you might be able to use an annular cutter/trepanning tool. However, he said it sounds like a two-tool job where you would open it up and then either bore it or use an indexable reamer.

If you need more assistance with your specific job, feel free to reach out to us. We'd be happy to help.
