Betalent carbide threading insert selection tips: 1, Internal threading or external threading. 2, The profile and pitch of workpiece thread. There is no rough and fine turning for thread turning tool, but the depth of the insert decreases gradually in the cutting process to meet the requirements of fine turning. In order to improve the productivity of thread turning tools, there are not only single blade, but also double blade, three blade, pipe thread is also equipped with comb.
Generally, there are classified to external threading insert and internal threading insert, in different threading systems, General 60°, general 55°，ISO metric, UN, STACME, API, W, NPT,BSPT, ACME,ABUT and UNJ.
