Cobalt vs Titanium Drill Bits?

Dewalt makes both.

I own both & cant really tell a difference.

Which one is better/stronger?

The pilot point bits are very similar in performance, with the cobalt being slightly better. The industrial conalt bits on the other hand are far superior to just about any bit on the market.

Thanks.

I have Dewalt 29, 18, 14 piece bit kits in Cobalt or Titanium with yellow cases & black lettering.

I noticed at Lowes there are now some with black cases.

Is Dewalt color coding their cases or is that the new style?

Whenever i see black cases it usually means that the drill bits are impact ready and have the 1/4 hex end so they can be used in a impact
