It operates using hydraulic force, allowing a licensed electrician to drive precise, burr-minimized knockouts through electrical enclosures, junction boxes, panel covers, and conduit bodies. The set covers a hole diameter range of 1\/2 inch to 2 inches, making it suitable for conduit entries from 1\/2 inch trade size through 2 inch trade size. The included 746 hydraulic ram delivers the force needed to complete each knockout cycle without manual hammering. This set is built for field and shop use by electrical contractors and maintenance electricians.\u003c\/p\u003e\n\u003cp\u003eThe 7646 is used in residential, commercial, and light industrial electrical work wherever conduit entries must be added to metal enclosures. Typical applications include adding knockouts to load centers, pull boxes, meter bases, and equipment enclosures made from mild steel sheet up to 10 gauge thickness. The included step bit allows the installer to drill the pilot hole required before the punch and die are seated. The set arrives in a plastic carrying case for organized storage and transport on the job site.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHydraulic operating method reduces physical effort and speeds up knockout cycles compared to hand-driven sets\u003c\/li\u003e\n  \u003cli\u003eRound punch shape covers hole diameters from 1\/2 inch to 2 inches\u003c\/li\u003e\n  \u003cli\u003eRated for mild steel up to 10 gauge maximum capacity\u003c\/li\u003e\n  \u003cli\u003eIncludes two draw studs: 20963 (3\/8 inch x 7.9 inches) and 2113B (3\/4 inch x 8 inches) for different punch sizes\u003c\/li\u003e\n  \u003cli\u003eIncludes 36613 step bit for pilot hole drilling and 746 hydraulic ram\u003c\/li\u003e\n  \u003cli\u003eStored in 30206 plastic case for job site portability and component organization\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with mild steel sheet metal enclosures and panels up to 10 gauge thickness.
