Review on π§ Bosch CO2149 4 3 Cobalt Drill: The Ultimate Precision Power Tool" by Brandon Rogers
crap! in Power Tool Parts & Accessories
I use cobalt drill bits (and end mills) whenever possible. Almost as good as carbide and many times better than HSS. If you're going to switch to stainless steel, you'll need at least cobalt.
Pros
- Power and Hand Tools
Cons
- Expensive
