Review on DelitonGude Cobalt Metric Suitable Steels by Will Jenkins
Sharp and Hard for Drill
I bought them for drilling 304 stainless steel sheet and carbon steel for threading 3mm holes. While they work, they stay sharp and don't break. I use CRC TrueTap cutting oil, moderate speed and moderate pressure.
Pros
- Works great and with good price, will be a good helper in your work.
Cons
- Not sure
