What replacement tooling does a Chicago Dreis & Krump press brake use?
Chicago Dreis & Krump press brakes built in United States are most commonly supplied with the American 1/2 in (12.7 mm) shank interface. That is the starting point for any replacement, and it should be confirmed by measurement before a tool is ordered, because the clamp fitted to the individual machine is what actually decides the tooling.

How do I confirm the tooling interface on a Chicago Dreis & Krump machine?
Measure the tang width and punch height, inspect how the punch is clamped, and measure the die body. Those four observations identify the family on almost every Chicago Dreis & Krump machine without a site visit, and they are what we need in order to quote a replacement.
- Measure the tang width across its widest point.
- Measure the punch overall height from the shoulder to the tip.
- Look for locking pin holes or a retention groove, which indicate a safety tang.
- Measure the die body width and photograph the clamp with a ruler in shot.
What is worth knowing about Chicago Dreis & Krump tooling?
Chicago Dreis & Krump machines are widely used in general fabrication with American style tooling.
- Tooling families share nominal dimensions more often than expected, so measure rather than assume.
- The clamp, not the tang alone, decides which holder and tool family will fit.
- If the measurements are ambiguous, a photograph of the clamp with a ruler in shot resolves it.
What do Chicago Dreis & Krump owners usually ask for?
The replacement requests below are the ones that come up most often for machines of this make.
