Review on 🔌 Hydraulic Knockout Electrical Conduit by IBOSAD by Jason Bollinger

Oddly the hardest part is getting the swivel head in the right position to put it back in the case. This is, as they say, better than using a hole saw. Today I drilled a dozen 1" holes in the back of some 4X4 boxes, which took about five minutes. It's as easy as piercing a beer can with a pocket knife. I'll give five stars if it's still going strong after six months. Oh, and the case is pretty darn good, as is the price: about half what a well-known brand can afford.
