Review on Enhanced Concrete Core Adapter - Toolocity AD1112 by Robert Aliraqi

Yes, you need that along with a Toolocity drill/drill. Yes, your new Toolocity hole saw is useless without this handy, trendy adapter. You can find others available but will the quality be as good? The best part is that you only buy it once and it goes with many other bits available from Toolocity. It has flat sides so it doesn't rotate in the chuck like the cheaper versions. Thank you Revan
