Introducing Smitty’s Knock Out Punch!
An Engineered Wood Ceiling and Floor Truss Hole Punch
Smitty’s K.O. Punch is the only tool that will efficiently fix the problems that contractors are having with making holes in engineered wood I-beams. The K.O. Punch is also the only unit with a self cleaning head and does not require a ladder to reach most ceilings. The tool is not just for engineered wood trusses or joists! Smitty’s Tool Company also has a smaller punch assembly with a self cleaning metal punch die for horizontal holes in metal framing studs.
What is the K.O. Punch?
An Easy-to-Use, Ergonomic Ramped Cam Tool that Packs a Punch
Smitty’s K.O. Punch is a different, more powerful way of creating the holes necessary for running electrical, plumbing or other trade materials through engineered wood ceiling, floor trusses and joists. Instead of drilling or sawing holes, it punches holes through a unique and masterfully designed ramped cam, self-cleaning punch head that creates ½”, ¾”, 1″, 1¼” or 1⅜” holes. The die can changed quickly by slipping the desired size into the head. The tool’s unique use of fulcrums creates an astounding and unstoppable 1 to 132 pound force ratio with 1,500 pounds of pulling force.
