Variety of sizes. some have a diameter smaller than stick pin. I was amazed to see how durable they were. Nevertheless they require careful use.

Used product in high speed tool to bore holes in soft copper. Using very slight pressure, the smallest 5 bits snapped off immediately on contact with material.You would need very specialized equipment to use these bits, which is impractical as they are advertised for hand held rotary tools.

I break them fairly easily. It could just be me though.

I’m sure they’re made for plastics and softer material. Not very good for metal. I keep breaking them.

They work great until they unexpectedly snap off while you're using them. But they cut and drill perfectly until the snap lol so not very sturdy. If you're wanting a set if micro bits that will last you more than 2 or 3 uses or plan to get regular use out of them, its probably best to skip these and invest in a more expensive or a professional grade set. That will save your wallet in the long run since these need constant replacements.
