These are stiff as nails but the size of your hair so bad things are bound to happen when you touch the end with any force or bump it like I’ve done a few times in my 3018 cnc. Don’t go fast and make sure there is no wobble in the spindle shaft or collet. I keep using my iPhone to take slowmo videos to ensure there is no wobble and then reset it in the collet if there is. If you don’t fix this, it will break shortly. I run it at 5mm per minute at 1,000 rpm with flatcam/candle. With an upgraded spindle you will likely get more speed but you will likely have to break a few to find the right speed. I still used it after the end broke off on a few, it doesn’t cut as great but is ok

One of the bits was broken on arrival. Still that's 9/10 bits arriving... so I'm going to let it pass with a middling review.

La mèche a cassé au premier trou et deux autres seulement en les manipulants. Je suis peut-être malhabile.
