Finishing shell reamer for metal fi 56

Finishing shell reamer 56 H7 machine NRNb, with a diameter of 56 mm, complying with DIN 219. It is a slip-on finisher, with a B cone shank, with chip flutes, designed for finishing through-holes and blind holes. It is used for finishing the machining of holes after they have been previously drilled with a drill and reamer with a chip flute, leaving an adequate allowance of material for further cutting. The slip-on 56 machine reamers we offer are suitable not only for reaming holes, but also for correcting their geometry, removing irregularities on their surface and also for increasing the smoothness of the machined hole. They are suitable for various types of conventional machine tools (lathes and milling machines) as well as for modern computer-controlled numerical control machines. In our store we offer you modern machine reamers, made entirely of HSS high-speed steel. They are distinguished by better cutting properties, the ability to machine hard materials of the P1.2 - P1.3 class, as well as a longer service life.
