Abstract / scope
ISO 3338-2:2007 specifies the dimensions of flatted cylindrical shanks for milling cutters — of diameters 6 mm to 20 mm for single-flatted shanks, 25 mm to 63 mm for double-flatted shanks and 6 mm to 32 mm for shanks with an inclined clamping surface. In the case of single-flatted shanks, it is applicable to both single-ended cutters and double-ended cutters, as double-flatted shanks cannot admit single-ended cutters.
