Finishing shell reamer for metal fi 72
Modern finishing shell reamer 72 H7 NRNb, diameter 72 mm, made according to DIN 219A dimensional standard. It is a slip-on finishing reamer, with a taper shank, with straight chip grooves for machining blind cylindrical holes. It is suitable for machining requiring an increased H7 tolerance, without the need for additional tool guidance. NRNb machine reamers improve the geometry of drill holes, remove very small excess material, level out unevenness, and improve the smoothness of hole surfaces. They are made entirely of modern high-speed steel HSS - High Speed Steel, thanks to which they are characterized by increased resistance to very difficult cutting conditions and also greater resistance to abrasion and mechanical damage. Slotted reamers 72 are suitable for machining parts made of materials classified as P1.2 - P1.3 on conventional machine tools and CNC numerical control machines.
