Review on 🔧 Irwin Tools SPEEDBOR 3 Piece 3041003: Optimize Your Drilling Speed with Precision by Sirious Cavalli

Oh my god they really want it! the ends are already over. I've tried hole saws in the past and haven't had regular drill bits large enough. However, these things made it quick and easy. No problem drilling a big enough hole in a matter of seconds. I've read that some people struggled with their drill bit being powerful enough. I use. 20 volt smaller Black & Decker and it was a little stuck and wanted to freeze but I found that if I hold it horizontally so the sides don't grip so tightly and pull it back a bit before it gets stuck and of course a fully charged battery , then there are no problems. I cut 3 holes about 6" deep for each of the 1 new battery. It's great.
