Choosing thread turning inserts
Start with the thread. Match the thread form and pitch named in the title to the thread you are cutting, then choose between an external and an internal insert code for the job, and between left and right hand to suit the tool and the direction of cut. Check the insert size and code against your holder or boring bar before you order, because the insert has to suit the holder pocket. The grade is shown in the product title; check the product page for the application the grade suits. Our guide covers the main insert decisions: indexable inserts. Always check the product page for the specification and application before you order.
