Cobalt Drill
Welcome to Center Bits!
Thank you for visiting our site. If you are looking for information about a Cobalt Drill, you have come to the right place.
What kind of drill bit do I need to drill through a VERY hard camshaft?
It’s on my kids go-kart so can put in a grease fitted clutch. I’ve tried a cobalt, but it dulled out without doing much. I used it at LOW speed & with some all purpose oil as coolant. I don’t know what else I can use to get through this tough metal camshaft.
Carbide. As fast as your drill can go. Will cut like butter.
Solid carbide, not carbide tipped.
Added: A thumbs down obviously means you know nothing of heat treated steel.
