Technical guidance & FAQs

Applications and materials

WIDIA NT inserts are 60° partial-profile thread-turning inserts in sizes 2, 3 and 4. The selected range includes TN6010 and TN6025 grades and right- and left-hand forms.

Choosing a configuration

Choose external or internal threading first, then match pitch or TPI range, seat size, hand and grade. Use the selected article’s radius and profile distance when comparing configurations.

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.

Are the NT external and internal pitch limits identical?

No. The specification table lists separate external and internal ranges for each size.

Does a left-hand boring bar always take a left-hand insert?

No. The verified A-NNT boring-bar combinations use opposite bar and insert hands. Select the exact pairing in the compatibility list.

How do I request the exact configuration?

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