Review on 🔧 Z-Knife Threaded Insert Installation Guide by Brad Lovro

I ruined a brand new skateboard deck trying to use these rubbish threaded inserts. The drill included in the kit bent after the second attempt to drill holes. I went ahead with another cutter at the correct depth, but when using the supplied flange cutter it also bent like hell, leaving the threaded insert about 4mm outside the hole. Now it is impossible to leave or enter the deck. This set is complete rubbish, don't use it for anything, you will regret it beyond belief. What a waste of money and time.
