DESCRIPTION
iTOOLco’s Gear Punch™ Set is the best tool for punching conduit-size holes into steel electrical panels
and boxes. No other tool can produce a hole as precisely as the iTOOLco Gear Punch™.
iTOOLco’s Gear Punch™ punches standard hole sizes ranging from ½” through 6” conduit sizes with 12
different punches and die to fit a variety of applications. Rated for use in mild steel or stainless steel,
the iTOOLco’s Gear Punch™ can also punch through aluminum and comes with an unprecedented six
year warranty and a lifetime replacement on draw studs.
iTOOLco’s Gear Punch™ (GP01) is powered by any make and model of corded or cordless drill – new or
old – with no special add-ons required. Punches and die are clearly marked with trade standard conduit
sizes and well as Center Point™ Knockout Layout Tool (CP02) marks for perfect alignment no matter

iTOOlco’s Gear Punch™ is compatible with punch and die offerings and comes with a Center Point™
Knockout Layout Tool accessory designs to help users quickly layout and punch knockouts. Using the
Center Point™ tool makes measuring for slug busting 70 times faster than a using a tape measure
