D237DN Double Notch Unit

This unit will accept 237DNI inserts for notching rounds, squares, rectangles, and special shapes of tubing and pipe up to 2" standard (2-3/8" OD x .154" wall). The die will notch both walls of one tube end in a single press stroke. The unique self-contained, spanker style design requires a minimum 3.5" stroke to operate and with no mounting to press ram required, larger stroke presses can be used. Die design also allows for tool area to hang over the press bed so you can notch bent piece parts. Along with standard 90° radius notches, custom configurations are possible. Unit can be used in a mechanical press, stand alone hydraulic press we offer (see Press Section for available options) or can be furnished as a hydraulic unit as illustrated below.

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.
