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.
