237DNI Double Notch Inserts

These inserts are manufactured to the specific application notching both walls of a single tube end per press stroke. Cutting members are manufactured of hardened D-2 tool steel for maximum tool life and are easily removed for sharpening purposes. Includes air blast to assist slug removal, where applicable. Unique tool design utilizes fixed positioning of inserts minimizing tool changeover time.

Inserts can be manufactured for conventional notching of tubes to fit another tube of equal or different diameter for 90° joints. Can also be used to produce slots, v-notches, and many other configurations on tube ends within the capacity of the unit.
