This standard specifies the dimensions and marking examples of machine reamers with Morse taper shank with blade inclination. This standard applies to machine reamers with a Morse taper shank of high-speed steel belt blades with a diameter greater than 7.5mm to 40mm. This standard specifies only metric dimensions, and only metric dimensions are recommended in the future. This standard lists two tables, one is the preferred size and other corresponding sizes; the other is the size of the diameter segment. Reamer length tolerances, cutting part diameter tolerances and shank diameter tolerances are also specified.
