1 SCOPE AND FIELD OF APPLICATION
This International Standard specifies the dimensions of tapered die- sinking cutters with plain parallel or parallel flatted shanks.
These cutters are in particular intended for directly obtaining clearances of moulds, patterns and dies, when these exceed2° 52'.
This International Standard applies to flat-end cutters and ball-nosed cutters.
Three types of cutters are standardized: short type,medium type, and long type in conjunction with the useful length l.
Parallel shanks are in accordance with ISO 3338/1 and 1I.
