Review on 🔵 Laniakea 8-Inch Bi-Metal Hole Saw 203MM M42 Annular Hole Cutter HSS - Ultimate DIYer Tool Set with Arbor in Blue by John Koch

My other hole saws quickly attach and detach from the shaft. This saw is quite complex and I assume it should fix everything firmly. The kit included a locking ring that was difficult to remove even with a pair of pliers. Finally picked up. Does it turn on after assembly? Who knows? There were no instructions, I had to look at the photo in the ad to make sure I connected everything correctly. . These alignment pins were a pain to install. Haven't used it on my drill press yet. A short video or instructions would not hurt.
