Hougen-Ogura 75532 7/16 in Round Hydraulic Knockout Punch

The Hougen-Ogura 75532 is a new 7/16 in (0.4375 in) round hydraulic knockout punch, sold individually as the punch head only, designed for use with Hougen-Ogura hydraulic punch driver units. The punch body is hardened tool steel with a black oxide finish, and features a brass-tipped drive stud for secure seating on the punch rod — a construction detail visible in the photos and consistent with Hougen-Ogura's standard PONCH-RD series design. The "PONCH-RD" designation confirms this is the round-profile punch (as opposed to square or knockout conduit punches), and the stamped 7/16 size on the face denotes the hole diameter produced in the workpiece. Compatible with Hougen-Ogura hydraulic punch driver units that accept this punch rod interface; the included instruction sheet (IOJIN.0702) details installation via retaining nut (Diagram A) or quick-change coupling sleeve (Diagram B). Typical applications include punching clean round holes in sheet metal, electrical panels, enclosures, and structural steel up to the rated capacity of the driver unit.
