Tough as nails.
Good bit, definitely cobalt. Used it to slightly enlarge 5 holes in hardened tool steel, which would have killed most bits. Got about as hot as anything I've drilled (small workpieces pinned into a wood block to hold them in proper position without ripping off any body parts!) and the bit just kept going, still sharp and making nice long metal curly-Qs despite nearly setting the jig on fire. Bosch makes good bits!

Great quality bit
This worked great for me. It's an odd size (not usually found in a bit set) but I needed this exact size. I had gotten one at the local orange big box store, branded with a drill manufacturer name but it wasn't true, which means it wobbled at the cutting end. This Bosch was absolutely perfect, straight and true and did the job perfectly in my drill press. Bosch makes great tools and this bit worked perfectly.
