Indexable threading inserts for thread turning
Compare Top Notch, laydown and TopThread inserts
Find Kennametal Top Notch NT, Kennametal LT and WIDIA TopThread NT threading inserts by exact article, profile and grade. These are distinct insert systems; select the interface that matches your holder.
Partial-profile and full-profile selection
Compare the required thread form and pitch with the selected configuration. The range includes 60° partial-profile configurations and Kennametal UN and ISO full-profile configurations. Check internal and external pitch ranges individually where listed.
Size, hand and grade matter
Match the insert size and hand to the holder seat. Then select the grade using the exact configuration’s published workpiece-material suitability. Shared dimensions alone do not establish a valid substitution.
Technical references and compatible holders
Use the selected product’s specification row, relevant technical documents and compatible-holder links together. Keep the manufacturer article number with your quote so the configuration is unambiguous.
Can I substitute a different threading insert grade?
Check that the exact geometry and holder interface match, then assess the replacement grade for the workpiece and operation. Ask Tech Tool to review the complete article numbers if changing a configuration.
How do I request a replacement insert?
Provide the manufacturer article or complete catalog designation and grade, the quantity, and the holder article if known. Include the thread form and pitch when selection help is needed.
