Review on Enhance Drilling Efficiency with Koopi BI METAL Replacement Tools for Plastic Cutting by Keith Alvord

I've bought several table spacers for cable management but didn't have a 2" hole saw on hand. I tested Revain and was pleasantly surprised to find it. It worked great for what I needed. I used it to cut through an Ikea table (the paper filler is sandwiched between the fiberboard). Worked great. The sockets fit well and are secure.
