The 124AV is a replacement knockout punch die manufactured by Greenlee for use with 3/4" conduit applications. It produces a 1.115" (28.3 mm) hole diameter and is designed to work with the Slug Buster punch system, which features a unique punch profile that splits slugs for easy removal. The die is rated for punching mild steel up to 10 gauge (3.5 mm) thickness and can also be used with aluminum, fiberglass, and plastic materials. It is compatible with manual, ratchet, hydraulic, or battery-powered drivers and uses standard Greenlee draw studs. This die is commonly used in electrical and construction applications where clean, efficient knockout holes are required in conduit and similar materials.
