10-Piece Hole Saw Kit for Wood | Durable Carbon Steel Power Drill Hole Cutter with High Precision Cutting Teeth – Woodworking HCS Hole Saw Kit for Wood, PVC, Plastic, Drywall

I was needing to drill assorted size holes in 2 pvc piping. This set worked perfectly for that project.

I was looking for a hole saw kit to install a new deadbolt onto an exterior door. The instructions for the deadbolt said I needed 2-1/8 and 1 holes so I looked for a kit that included both of those sizes. Surprisingly that was kind of difficult to find. I could easily find kits with 1 or the other size but this was the only kit I could find with both sizes I needed. So I give credit for including those sizes, which I imagine are standard for installing a deadbolt or door knob. My problem with this kits comes from the quality. The metal of each of the bits is extremely pitted and looks to be scratched up and used, but was not. Very poor quality control. Also the case they came in is very cheap and the plastic latch is extremely flimsy and will break off after opening and closing a few times. This is not a tool I will need often, potentially ever again, but I would likely look for a better quality kit if you are searching for hole saw bits.
