    • 5.0 out of 5 stars Quick, easy way to make a clean 3.5" hole.
Size: 3" Style: Punch, Die & Draw Stud
Review Image by Glenzoni Glenzoni
I've used this type of hole-punch before, so I knew what to expect. I used this to make a nice, clean 3.5" hole in 12g steel plate. Used a breaker bar for added leverage, but other then that, it was quick and "easy". Way better then a hole saw, but cost a lot more too. Still, it's a heavy duty tool and does what it's supposed to do. ... show more

    • 5.0 out of 5 stars As a previous reviewer mentioned this kit replaced a Harbor Freight kit that I used a few times.
Size: ½ - 1¼ Inch Style: Punch, Die & Draw Stud
As a previous reviewer mentioned this kit replaced a Harbor Freight kit that I used a few times. The Harbor Freight kit was poor quality. The punches were prone to cutting into the dies and required much more torque or force to produce a hole
