Any comment on the cobalt ones I linked to earlier? https://www.georgehenry.co.nz/shop/Cutting+Tools/Drills/Evacut+Cobalt+Drill+Prepack+Metric.html"The Evacut Cobalt Jobber Drill bits are an industrial quality accessory for drilling stainless steel and other tough materials.
If you use standard 118-degree drill bits, you need to center drill first, regardless of materials. This keeps the drill from walking.
If it is hardened material though I would have doubts. Anything you can do to check that?
