## Description

B BOSI TOOLS Cobalt Drill Bit Set 19PCS, M35 Drill Bit Set, High Speed Steel Twist Jobber Drill Bit Sets for Hardened Metal, Stainless Steel, Cast Iron, Wood with Index Storage Case

Review: I'm really happy with this drill bit set. Right out of the box, I was impressed with the quality, especially for the price point. First off, the storage case is excellent. It's solid metal, not a cheap plastic clamshell that's going to crack or have the hinge break after a few uses. Inside, the bits are held in a convenient tilting rack that makes it easy to see the sizes and grab the one you need. It's a well-thought-out design. The bits themselves look and feel very well-made. They have a good weight to them and a clean finish. Most importantly, they perform great. I've used a few of the sizes so far on some steel and hardwood, and they cut cleanly and efficiently. The 135-degree split point tip does its job well—the bit starts cutting right away without wandering or walking. Overall, this is a fantastic set. You get a great range of common metric sizes, sharp bits that cut true, and a durable case to keep them all organized. Highly recommended.
Review: These metric drill bits are good quality & work well.

The drill bits a pretty good for the price but the case is awful. It jams and the holes don’t line up great so I’m always fighting to get the bits in and out of the case
