Overview
Greenlee is known for punches built to cut clean, round holes through sheet metal and electrical enclosures, and the 7235BB carries that lineage at 3 pounds in a case sized about 12 by 9 by 2.5 inches.
The case dimensions likely cover the punch and its interchangeable dies together rather than a single hand tool, which is typical of Greenlee's electrical knockout punch kits. This listing does not itemize which die sizes ship in the box, so confirm exact fit on Amazon's product page before buying for a specific conduit size.

Who it's for

Pros and cons

Performance notes
At 3 pounds the tool has enough heft for a driver or ratchet-style punch rather than a lightweight single hand punch, and the compact case size suggests it is meant to travel in a job bag.
