Bits for hand drilling hardened steel
Posted: Fri Sep 27, 2019 6:23 am
Greetings.
I'm looking for a set of drill bits https://mechanicfaq.com/drill-bits-for-hardened-steel/ for drilling out tough bolts, such as hardened exhaust studs. (Even with my favorite dewalt HSS drill bits I often have a really bad time getting anywhere.)
I've read a few sparse comments about solid carbide bits being great but I never used them, and I can't find sets of them anyway. Are they worth the price (like $25-40 a bit)?
