What does this mean?Pros & Cons
Pros
They appear to be more useful for light engraving like printed circuit board etching than any kind of milling. The ability to drill cleanly, quickly, and precisely is why i will keep buying these, despite the problem with breaking.
Highlights
Quality
Good quality carbide but the accuracy could be a bit better.
Competitiveness
I use a proxxon bench drill running at 8500 rpm, works fine for drilling pcb boards.
0mm size to open up predrilled holes on freshwater pearls.

You will not be able to use this product successfully at low speeds and with a hand held drill you will probably snap the drill bit when you have drilled a hole and are extracting the bit out of the hole
