Knock Out Punch Set (7) Piece Set (Tube Sizes) -Part #: mp-00061873

Looking to improve speed, accuracy, and cut quality when punching holes in plate steel? SWAG Knock Out Punches eliminate the common issues of hole saws—no more catching, walking, or rough edges. Made in the USA from domestic 4130 chromoly steel, these CNC-machined, heat-treated dies are built to last and can punch up to .1875" aluminum, .125" mild steel, and .083" chromoly or stainless. They’re designed to be used with a 10 Ton Hydraulic Knockout Punch Driver (sold separately), making them ideal for high-volume or hard-to-reach applications. Note: These dies use 3/4"-16 TPI threads for larger punches and 7/16"-20 for smaller ones, and are only sold as complete sets.
