Conclusion: ISCAR's recommended threading family in order of priority;
1 choice - ISCAR threading laydown line, M-type insert
st
nd
2 choice - PENTACUT thread family, ISCAR threading laydown line, B-type or G-type insert
3 choice CUT-GRIP thread family
rd
Economical Consideration
economical efficiency • what are the number of cutting edges on the insert?
ISCAR threading laydown line inserts have 3 cutting edges.
PENTACUT inserts have 5 cutting edges
CUT-GRIP inserts have 2 cutting edges

Conclusion: the decision to choose any of the selected tools is not only based on the technical parameters of the
tool, but also on other important factors such as stock availability, cost, terms and conditions of deliver, etc.
