I make a lot of miniatures so I use drill bits for wood, plastic, copper, brass and other soft metals. These work well enough on all these soft materials but they are not very sturdy at all. I have snapped many different sizes when I just set my drill down or just torque them the tiniest bit so care is needed when using these.

Like these bits, mostly use them on small lathe for precision drilling.

There are no markings to tell you the size of each one. The colors mean nothing and don't match the picture. You can assume the size, if you keep them in order and go back to check the sizes on the listing.

Very very poor quality, no size indication that can be read, return is to Hong Kong and not Australia. Bits break easily.

They break easily. A hand-held Dremel may not be the best tool to use...maybe a drill press is needed. Good luck.
