11ER Full Profile 60 degree 0.5-2.5mm Pitch Metric ISO External Threading Inserts

Full profile 60 degree metric 11ER threading inserts, suitable for SER 11 type internal threading toolholders.

Full profile inserts means the crests of the thread can be turned down to the correct major diameter in a single pass, unlike partial profile inserts which require a separate turning operation. However, this also means each insert is only suitable for cutting a specific thread pitch.
