High-Performance Carbide Insert Holders for External Threading and Grooving
Pair these holders with a threading insert or a grooving insert to make cuts on the outside of a 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 external holder with a right-hand insert when the workpiece is rotating counterclockwise (toward the lathe operator).
Use a left-hand external holder with a left-hand insert when the workpiece is rotating clockwise (away from the lathe operator).

High-Performance Carbide Insert Holders for Internal Threading and Grooving
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).
