Nice Assortment of Sizes and Very Sharp. Fits easily into a Pinvise for Precision Work.

I run across these from a Youtubers video whom is a scale modeler. ( GrandpaMark's Hobbies) If I hadn't have watched his video I wouldn't have known these existed. All for such a reasonable price! They was shipped quickly and I received them on the second day after the purchase! Durable case, very well machined bits . The drill size is printed on the end of each drill shaft tip. They do fit in a Dremel collet if one was prone to using them in a power tool. Or a hand finger drill handle. Known as finger bits they have a durable composite ring for easy hand drilling use. Not cumbersome but easily articulated in the finger tips. Highly recommend to anyone needing micro bits

I use the micro drill bits with my Bauer 0.6 amp variable speed rotary tool. It is not very strong, I think it is a perfect match for these bits. I use them for model building. Nothing demanding.

Nice collection of basic bits, considering the price. Unlike the other similar drill bits sold at Amazon, this one comes with the case (the other shows the case but reviews say they come in individual sets of 5). Drilling has been clean and has met my expectations. Obviously be careful as these are tiny bits - use them on a CNC machine and be careful with the programming. I don't recommend using these by hand as they will be very easy to break.

Carbide bits can do what other excellent quality drill bits can't. Need to drill into stainless, fiberglass or a piece of mirror? These are useful. Now with the mirror I only used the carbide bit to start the hole. Diamond burrs made the actual hole.Common complaint is breakage during shipment. This needs to be looked into and solved. The smallest bit is less than 12 thousandths of an inch diameter. At that diameter and being made of hard material it might get broken by looking at it cross-eyed. All my 0.1 mm arrived in pieces. A couple of 1mm bits also didn't survive the trip. If you expect 100% good parts I'd suggest a vendor that prices their bits at $5 or more each. If you need the 0.1mm bits don't buy them here. You will be disappointed!I'm hoping to be contacted about the broken bits. 80% survival still works for me. I was about to place a $75 order for 10 bits.
