high quality consistent throughout the bits. used carefully they will keep their sharpness and last an amazing long time. get sloppy and they will break immediately. I'm using them to drill pilot holes in hard wood and consistently get 50+ holes out of one bit. If I slip up, I don't get one hole and the shards are a mess to get out of the hole without marring the surface so be very careful. I will buy more when needed.

Had zero success with these. Disintegrate on touching the work-piece. I challenge anyone to show me a hole drilled through anything with these drills.

These are *not* useful for anything except drilling, they can't handle milling even at super low feedrates

I have been using regular cheap 0.5mm twist drill bits for two years. They are weak, not sharp and break all the time. I decided to try these and they are amazing. Orders of magnitude sharper and able to make a quick clean hole. Also much stiffer and just inspires confidence when drilling. I wish I found these sooner.

Perfect for drilling holes in models or soft materials. Good quality and quantity for the price.

I use these for all types of metal, except carbide steel. These are about the only type of drill bit that will drill into hardened tool and stainless steel.Definitely make sure there is no shear, and they are less likely to break, but in all honesty, these break easily if not careful. Take your time, or get something to motorize it!
