3.1 Cutting diameter
Table 1 gives the series of cutting diameters and their related tolerances. The main dimensions of the cutting part of hardmetal burrs are specified individually in ISO 7755-2, ISO 7755-3, ISO 7755-4,ISO 7755-5, ISO 7755-6, ISO 7755-7, ISO 7755-8, ISO 7755-9, ISO 7755-10, ISO 7755-11 and ISO 7755-12.
3.2 Cylindrical shank
Shank diameter shall be 3 mm and 6 mm, with tolerance h9. Shank length shall be in accordance wtih Table 2. The shank length is defined as the length of the burr minus the length of the cutting part as given in ISO 7755-2, ISO 7755-3, ISO 7755-4, ISO 7755-5, ISO 7755-6, ISO 7755-7, ISO 7755-8, ISO 7755-9,ISO 7755-10, ISO 7755-11 and ISO 7755-12.
NOTE These length ranges permit manufacture both of burrs with constant overall length and variable shank length, and of burrs with constant shank length and variable overall length. In the latter case, national standards are intended to indicate the agreed shank length.The agreed shank length shall be within the limits given in Table 2.BS ISO 7755-1 pdf download.
