Lichamp Manual Knockout Punch Kit, Heavy Duty Metal Sheet Knock Out Box Hole Cutter Conduit Punch Driver Die Set

This is a great product to put clean holes through sheet metal.

Sometimes I don't understand what people are talking about when they review a product. If I listen to most reviews I wouldn't have bought anything from Amazon. I don't know what people are trying to cut with this or how they used it but I have no experience in doing this and it worked perfectly. Cut a 3/4 hole in a pretty thick metal box, without the tool being damaged and the hole is clean. I don't recommend using a power tool with this. And faster sometimes is not better. If you're looking for an inexpensive way to punch a hole through some metal boxes this will work great, read the directions. Someone on here said it messed up after they cut stainless steel. Well the directions say do not use on stainless steel. Also you need to oil not with WD-40 but with oil after each use. Make sure everything is straight snug and go slowly to cut and you won't have any issues. And one more thing the size was perfect.

I used this set a day ago, I found them to be of good quality. I'm assuming the set should last a long time. I did find the threads on these are a bit rough (didn't go on very smooth), I think this should get better with use. I have used similar tools in industry use, I find these to be almost as good quality. I would recommend these for any workshop.

I needed to punch a 1.25” hole into my breaker panel for a conduit attachment. It worked fine. Was sharp enough and had a bearing to take the thrust load of pulling the punch into the die. I only successfully used it once. Not sure if it is sturdy enough for commercial everyday use. It probably is.

I usually buy cheap products to find gems that work as good as the more expensive brands. This is not that, this broke the first time I used it, the metal is not sharp on the knockout side made not sturdy on the main threads, this worked on the 1/2” and 3/4” but not on the bigger sizes, it got stuck midway I think the threads failed, no way to undo it I had to throw it away

This product was a great purchase for me - it is marked at a lower price point than similar products in the same tool family, however, it is of heavy construction and works well. I purchased this item to complete a sub-panel installation, therefore I needed to create multiple taps in the heavy steel body of each panel, both new and existing. These are easily connected to a ratchet set, which assists in creating the holes. Overall great product to have, whether for use in electrical work, making openings in metal stud framing or similar materials.

Not bad for price

I couldn't find hole saws the correct diameter for conduit so I tried these. Easy to use and I was successful on my first try. But I'll probably never need them again for the rest of my life.

Creo es la herramienta más sencilla que he comprado , solo resistió para una perforación y fue basura , pero pues no puede pedir uno más por ese precio

Très bon petit kit livraison rapide coté qualité ces bien pour le prix.

Did a 1/2 punch hole product works well for what it was design for as for the service was beyond what I way expecting I give them 10 star raitng , Thank you .

The punches work well.. but the small one has a design flaw.. least I can't figure out why they made it the way they did.. the draw bolt has a thinner part in the middle.. and you need to ensure the backer is not on this area, when you are tightening as it is off center so doesn't cut right.. the end of the bolt is larger and that backer doesn't fit there either.. so you need to carefully, hold it against a tapered part.. very weird.. but if you do it right no issues.. only reason for not 5 stars.. also the slug busting design of other brands sure makes getting the garbage out easy.. on the small one here the inside is larger than the cut point so the slug has to be pulled out with pliers.. again.. whole kit costs what other charge just for the small cutter.. if you are using all day every day.. don't buy this.. but if you want for the odd project.. great little package..

I am a retired electrician who has used this type of kit many times. I used this product to enlarge the K/O holes in 2 electrical boxes. The 1/2" kit only made one hole (with great difficulty) after which the thread on the bolt was showing signs of wear. These boxes were standard electrical boxes. The kit can no longer be used on the 1/2" punch which is the most common item.
