Review on 🔧 Efficient Drill Index Set Piece for Ultimate Drilling: DRL 240 00 by James Jenkins

Sorry Revain, but they're useless. Absolute waste of money and time. Unless you're trying to drill through a piece of foam or paper, they just won't drill. I think it's just untempered wire cuts folded into a small case. Some of them were exactly the same size. Worst purchase I have ever made from Revain. they are garbage.
