Install these inserts into a matching holder to cut external or internal threads on a workpiece. They are compatible with top-notch style threading, which uses a highly-rigid clamping design, resulting in a smoother finish and superior tool life. When the first point dulls, flip the insert to use the second point.

60° V-thread inserts cut a range of UN thread types and sizes.

NPT thread inserts efficiently machine full-profile NPT threads.

Pair a right-hand insert with a right-hand external holder or a left-hand internal holder. Pair a left-hand insert with a left-hand external holder or a right-hand internal holder.

Pair these holders with a threading insert or a grooving insert to make cuts on the inside of a hollow workpiece. A highly-rigid clamping design results in a smoother finish and superior tool life. They are compatible with top-notch style threading and grooving systems.

Use a right-hand internal holder with a left-hand insert when the workpiece is rotating counterclockwise (toward the lathe operator).

Use a left-hand internal holder with a right-hand insert when the workpiece is rotating clockwise (away from the lathe operator).
