Review on 🔩 Liyafy Adjustable Split Ring Screw Stop Collar Drill Bit Set - 7pcs+8pcs - Precise Hole Cutting Measurements - Pack of 2 by Chris Endricko

These drill stops[ The clamps are well made and come in two packs. Real men don't ask for directions and don't measure anything! And since this is entirely my opinion, I would assume that one box says metric and the other says SAE? I just put them on SAE bits and got the tightest possible fit for each size. Except for a tall guy who sat next to me because I didn't have one that tall. So some of them were a bit too big for the bit, but they could be tightened. I hope you can open my photos and see the size of the collar on it. I think this allows the collar to flex a bit? But for the accuracy I'm looking for I think it will be fine. They cover a wide range of cheap sizes, are on Prime, are as described and arrived on time. Appropriate!
