Review on Bi Metal 23 Piece Mandrels Galvanized Plasterboard by Daryl Fitch

No, this hole saw set cannot be used for "galvanized pipe” (as the name suggests), except in the sense that you can thread the galvanized pipe through the hole you make with one of these have made hole saws . But hey, English is tricky, especially if you're not willing to pay someone who actually _speaks_ English a few bucks to write a description of your product for you. But anyway. This is a pretty good set of hole saws. The steel seems good, the pergolas are definitely well designed and safe, and you get a good range of sizes. The larger sizes cut about 1.5 inches across and the smaller sizes cut about 1.25 inches across. Yes (as another reviewer notes), if you cut through something of any thickness, the cut plug will get stuck in the hole saw. But that's how hole saws work, as anyone who's used them will tell you. You can also burn yourself if you drill deep into wood. If you search "1ZSse6AW2cA" on YouTube, you will find a video with a trick that prevents sticking and makes removing the plug easier. This set comes in a case that was obviously made for a slightly different set of crowns and is fairly cheap but works well.
