HSS CO Cobalt 1Mm 5Mm Drilling Stainless Review

After I put this industrial drill bit to the test, I was thoroughly impressed with its efficiency and precision. The HSS CO Cobalt bit easily drilled through stainless steel without any issues, saving me a considerable amount of time and effort. The bit is also durable and can withstand heavy use on tough materials. The only con I found was that it is slightly more expensive than other drill bits in the market. Overall, I highly recommend this bit for any heavy-duty drilling needs.

I cannot comment on the quality of this product as I am returning it unused. They were supposed to be between 1mm and 5mm but all I received were within 0.03 of 1mm. Of course I would like to have an advertised set.

Drill bits are fine but title and description imply that this is a set of 1mm to 5mm bits, one for each size. in this case only 10 times more than drills with a diameter of 1 mm. Not rating it 1 star or reporting it as the name KINDA says when it says (1mm) at the end, but that is definitely very misleading.
