Technical guidance & FAQs

Applications and materials

Kennametal NT inserts provide a 60° partial profile for thread turning. Compare sizes 2, 3 and 4 in right- and left-hand forms, with separate external and internal pitch ranges.

Choosing a configuration

Select the required thread pitch or TPI, insert size, hand and grade. External and internal pitch limits differ; use the correct range for the operation.

Compatibility and use

Use the exact manufacturer-listed insert and holder pairing for the selected article. Match the thread form, insert hand and seat identity before ordering.

Technical documents

Use the linked thread-form and dimension reference with the selected catalog number. Cutting recommendations must match the insert grade and workpiece material.

Can the same pitch range be used for internal and external threads?

No. Use the separate external and internal pitch or TPI ranges in the selected article’s specification row.

How does NT insert size affect holder selection?

Match size 2, 3 or 4 and insert hand to an exact manufacturer-listed holder. A similar catalog name does not establish compatibility.

How do I request the exact configuration?

Select the manufacturer article, catalog number and grade, enter the quantity and add it to your quote.
