Review on 🛠️ YIYITOOLS Titanium Twist 21 Piece Including: Premium Quality and Versatile Tools for All Your Needs by Ted Higdem

This is a set of professional drills. They come in a durable case that will last for years and the bits hold very firmly in their holders. All are well marked on the holders and also engraved on each drill bit. By the way, the case is actually a regular hinge with a steel pin and not just a plastic hinge that breaks over time. I've tried drilling a few of these through heavy steel mounts and they worked great. Drilled very quickly and the drills were not damaged at all. They come in my work tool box and are used frequently. I highly recommend this YIYITOOLS 21 Titanium Drill Bit Set and I think the asking price is great!
