Then match the insert and holder.
Internal and external threading holders for lathe machining. Browse the products below and confirm the size, hand and insert interface for your setup.
Choose a holder
for bore access.
Open the product page to compare available sizes and insert information. Confirm the minimum bore, bar diameter and access requirements for the selected model.

Four checks
before you order.
Start with the threading operation, current insert code and machine setup. A similar-looking pocket does not confirm that two inserts or holders are interchangeable.
- 01Operation and workpiece access
Internal or external thread, workpiece diameter, thread depth, shoulders and clearance.
- 02Insert and seat compatibility
Complete insert code, size, geometry, seating surfaces, shim and clamping parts.
- 03Holder size and hand
Shank or bar size, working length, overhang, holder hand and intended cutting direction.
- 04Machine and coolant
Turret or tool-block dimensions, center height, coolant arrangement and the available mounting space.
Before you order.
Provide the complete holder and insert codes where available. Photos and drawings help when replacing existing tooling.
How do I choose between internal and external holders?
Choose according to the location of the thread and the available tool access. For internal threading, confirm bore clearance and bar dimensions. For external threading, check the shank size and available machine space.
Will my current threading insert fit a new holder?
Confirm the complete insert designation, size, seat geometry and clamping arrangement against the exact holder model. Matching thread type alone is not sufficient.
How do I select the holder hand?
Review holder hand together with thread hand, tool position, spindle rotation and cutting direction. Include the current setup when asking for help.
Can I order spare screws, shims or clamping parts?
Provide the exact holder code and identify the part from the product page or a clear photo so availability and compatibility can be checked.
