Technical guidance & FAQs

Applications and materials

Kennametal LT-ER-ISOCB inserts are right-hand external ISO metric threading forms. Compare the selected size-16 catalog forms by exact metric pitch, profile distances and grade.

Choosing a configuration

Use the required metric pitch and complete ISOCB catalog number to select the insert. Confirm the exact holder seat and grade; inch equivalents are not a substitute for the published metric thread pitch.

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.

Should I select ISOCB by metric pitch or TPI?

Select the ISO metric form by its published metric pitch. Use the complete manufacturer catalog number to identify the configuration.

Are all size-16 LT inserts interchangeable?

No. Size alone does not establish the correct thread form, pitch, hand or holder fit.

How do I request the exact configuration?

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