Review: Excelente , cumple con su Función
Review: Not only does it cut a perfect hole it cuts the slug in two pieces so it just falls out, instade of having to fight with it. the cutter housing turns on a bearing while pulling the cutting bit through the metal. We used it on Stainless steel with no problems. Make sure you have a good drill bit for metal, for the pilot hole, then use a step drillbit to get to the proper size for the threads to go through. When cutting bit does not slip and is very smooth.

## Questions & Answers

**Q: Can I use an impact (1/2" battery powered) instead of a wrench with this kit?  Or will doing that tend to break the studs?**
A: I wouldnt do it to mine. If i wanted to use a drill, I'd grab my hole saws. It probably would depend on what gauge/type of metal you are punching out. I broke my 1/2" die using a wrench on a stainless panel.

**Q: Is there a knockout for 1-1/2" stainless steel? If so, what is the part number?**
A: yes there is for the 1 1/2" and 2" just check on amazon and it will come showing you the kit

**Q: Are all of the knockouts slug busters, or is the picture right?**
A: the picture is not correct it shows 735BB knockout punch set which contains only one slug buster. The item for sale is the 7235BB slugbuster set which contains four slug busters.

**Q: what drill size is needed for the small bolt? And what is the punch size that the bolt fits?**
A: For the small bolt you need open a hole of 7/16"  This bolt is basically for the 1/2" conduit punch

*by D***D on 20 June 2016*

Use the 3/4 inch (nominal size) and the Arlington grommets for fishing pipework and wiring through steel track and for new knockouts in the studs. A good solution if you're not looking to by the steel stud punch for 500+ dollars to do almost the same job. This kit also has a few different sizes so it can be useful for other projects.
