Technical guidance & FAQs

Applications and materials

Kennametal Top Notch A-NE holders support internal threading. This family is listed in inch sizes; select the exact material number to compare the published holder dimensions.

Choosing a configuration

Check minimum bore diameter, shank diameter, tool length and F dimension against the bore and machine setup. Where a coolant supply size is listed, match that connection to the machine setup.

Compatibility and use

Match the exact holder, insert seat and cutting hand before choosing an insert. The catalog gauge insert identifies a dimensional reference; it does not establish that every insert in the same product family will fit. Published gauge references in this set include N.3R.

Technical documents

Use the dimensional table for the selected material number and the linked manufacturer holder reference when available. Confirm the exact replacement clamp, screw and key from that holder’s service-part list.

How do I choose between these Top Notch A-NE holders?

Check minimum bore diameter, shank diameter, tool length and F dimension against the bore and machine setup. Where a coolant supply size is listed, match that connection to the machine setup.

Does an inch listing mean every insert uses an inch thread form?

The holder’s native dimension system does not determine thread form or insert compatibility. Match the exact seat, hand, insert catalog number and required thread standard.

What should I include in a quote request?

Include the exact holder material number, quantity and required insert or replacement-part references. Available holder configurations are A16NEL3 (1094836), A20NEL3 (1094838), A24NEL3 (1094840), A32NEL3 (1094844).
