I used my rotary tool with the smallest bit an I expected a breakage; however, to my surprise, the bit went straight through 3mm of copper while I held my flex shaft tool steady, guide by a guide punch. The result was a nice clean hole and no overheating. Make sure to use a live such as Pepe Lube, Burr Life or the like.

I used it on an assortment of material ranging from Plastics to Brass Metals. I was worried with a few reviews saying that the drill bit will break off. So I decided to invest in a cheap drill press. The drill press keeps the drilling angle consistent unlike using a dremel or power drill angles which I think may lead to higher rates of bits breakage. Overall, well made drill bits. I have no complaints.

They are only good for a few holes before breaking . I only use them for plastic models and use them by hand , no dremel . After drilling a few holes by hand , you can count on them to break . The smaller the bit , the less holes it will drill before breaking . They work well but are very fragile .
