Selection guide Cutter pitch Select an appropriate cutter pitch to optimize performance while considering machine stability and capacity. Power requirement is often a factor limiting the possible number of cutting edges that are engaged in cut. Coarse pitch, -L Cutter with low number of edges. • First choice for difficult machining conditions • Limited machine power and stability • Long tool assemblies • Full slotting operations • Long-chipping materials ISO N (large chip pocket) Close pitch, -M Cutter with medium number of edges. • First choice for average machining conditions • Good productivity • Good chip space for roughing in ISO P, M and S materials Extra-close pitch, -H Cutter with maximum number of inserts. • First choice for stable machining conditions • Ideal for short-chipping or heat-resistant materials • High productivity with low ae , more than one tooth is always engaged in cut Even pitch Even or differential-pitched cutter Differential-pitched cutters have unequal spacing of the teeth around the cutter. These cutters are advantageous because they break up harmonic vibrations, which in turn increases Differential pitch stability and reduces the risk of vibration. This is especially useful when milling with large width of cut and long overhangs. Note: An X added to the code describes a cutter version with a slightly closer pitch than its basic design. 7
