today I want to tell you about knock-out tool. It is mostly used by electricians, technicians, and sheet-metal workers
it is used for extra large holes
if you want to buy this tool it must be high quality. Its edge is sharp, hard, and precise to fit inside the die
I already made a some holes on this sheet
now I will show you how this hole is made
let's see
this knock-out tool has 2 different types of studs, I will drill the pilot hole first.
now I already made a hole exactly the size of the stud
now I insert the die inside
now I tighten the cutter-die
you can use a wrench
but I want to use an impact gun
now you will see the cutter start moving inside the die and cutting the steel sheet
now you can see the perfect hole inside
we can do the same thing for the other, bigger hole
do the same setup for the bigger die
use an impact gun and you can see another perfect hole
