Review: Durable, Sharp, and Great for Tough Materials! - This drill bit set exceeded my expectations! The cobalt M35 HSS bits feel extremely durable and handle tough materials like stainless steel and cast iron with ease. They stay sharp even after multiple uses, which is a huge plus. I’ve used them on metal, wood, and plastic, and they perform consistently well across the board. They cut smoothly without excessive force and don’t overheat as quickly as standard bits. The included storage case is also a nice touch—it keeps everything organized and easy to access. Overall, this is a high-quality, reliable set that’s perfect for both DIY projects and more heavy-duty work. Highly recommend!
Review: Great price, good quality - Pros: good price, does the work, dozen pieces, container keeps everything organized, cobalt coating, Cons: I don't see any So... This was an easy choice, compared to what's available right now locally and online this is a very good price for this, and it came with a dozen in a case that doesn't take too much space in my tool bag, I used to like the metal cases until they start to smell and rust, so for expendables like bits this is perfect. Easy to use, because it's easy to open. Good quality, sharp edges makes this my go to bit drilling. And the case is bendable enough but won't tear up my fabric too bag.

### ⭐⭐⭐⭐⭐ No issues
*by R***E on January 25, 2026*

At $1 each I think these are a pretty good value. They seem to be a decent length you don't want them to be any longer because when it comes to small bits like this the longer they are the easier they are to break. I love that they come in a nice little plastic case to keep them from rolling all around and you don't have to fidget with an envelope or a bag every time you want one. And when all your bits are gone you can repurpose the case which adds value. They seem to be a sharp bit and the coating seems to be good and they start nicely without having to punch a divot. I do auto body and I come across a lot of very hard materials such as high strength steel and ultra high strength steel which I have not yet tried these on. I have tried them on mild steel sheet metal and drilled at least a dozen holes and have had no issues. Time will tell how good these bits are and how well they sharpen but as for now I think there is value in this product and I probably wouldn't hesitate to purchase them again
