                      Hard reaming instead of eroding:
                      Enormous savings thanks to HR 500

                      Guhring’s HR 500 high performance reamers are not only first choice for volume production.
                      They are also the ideal solution for especially demanding machining tasks.
                      They replace the expensive eroding operation of highly accurate ejector bores in hardened
                      steel. Advantage for the customer:The machining time of in excess of 30 minutes per bore for
                      eroding is reduced to less than 1 second with hard reaming.
