Two bits in this set were broken before they shipped. No broken bits were found in the case, just two shanks with no bits, and those were the two largest diameter bits. I tried using a .2mm bit to drill through the soft plastic case they came in, just to experiment. Snapped off before I got all the way through and I haven't bothered trying the rest. I would give this a one star rating but it's the holiday season and I'm trying to be good so Santa will bring me a better set that's made in 'murica.

Drill bits broke within seconds of touching the PCB, reaching about 1/4th of the way through a 1.6mm thickness PCB using a dremel drill press (so no sideways force was applied), might work better for softer materials, but certainly not copper or the internal material of the PCB

I am so excited about these. I am a metal smith jeweler and these are going to work great for making small detail or to start holes for saw piercing

I bought these drill bits for plastic modelling and crafts and will use them with Dremel Micro rotary tool. I do not need extra collets. Drill bits fit into the regular one. In plastic models I easily do 0.1mm holes, but pay attention to rotary tool speed. With such small drill bits you better use the lowest speed you may set, otherwise you may break your dril bits.

These are perfect, easy opening case, come color banded as advertised. Case opens in two halves and bits stand up straight for easy access. Not to small,can be hand held for use, or put in pin vise. I've already used the .25 on one of my models. Bit into the plastic right off, didn't walk, made clean round holes with no remaining flash or excess. Every modeler should buy a set. These in my opinion are the best I've purchased so far for precision drilling of small and miniature plastics. I must apologize to Daewon Industries for the review and comment I made earlier. The bits that I received earlier were not from them, did not have the colored collars, a case of equal quality, nor did those bits work well on styrene plastic.
