KATO Tang Break-off Tool

KATO Tang Break-Off Tools

Easy Tang Removal.

The KATO Tang Break-Off Tool (KTBT), as the name implies is a spring-loaded punch designed to cleanly break the tang from conventional CoilThread inserts once they have been installed. KATO recommends that the tang be removed from the insert after installation. The standard KTBT tool is designed to break off tangs on inserts up to 2 diameter in length. A longer punch is needed for 2.5 & 3 diameter nominal length inserts.

To eliminate the tang break-off process, and to ensure a FOD-Free assembly, consider switching to KATO Tangless CoilThread inserts, there are no tangs to break-off, retrieve or lose!

The Tang Break-off Tool is important

The KATO Tang Break-off Tool is an important tool when installing tanged inserts. Some unwisely undervalue this tool. The advantages offered by the KTBT should not be ignored. If the tang is not properly removed, the hole may be compromised and will not allow the male fastener to pass through. The best way to remove the tang is through a sharp strong force directed away from the installed insert.
