What about the product?

These are good general purpose drills and are advertised as being for hard metal. That is generally true although I have broken some while trying to drill out a lock on a door that was sabotaged by a tenant on a rental property. Most of the time they will drill through hard metal although using a lubricant will help extend their life

I have a very dense hard brick and i've used milwaukee titanium bits that all break. should i use the cobalt or is there something better?

You would use a masonry bit for drilling brick.

What are the sizes of the bits? It's hard to see the ones behind, on the picture.

The bit sizes are as follows (all units are in inches): 1/2; 31/64; 15/32; 29/64; 7/16; 27/64; 13/32; 25/64; 3/8; 23/64; 11/32; 21/64; 5/16; 19/64; 9/32; 17/64; 1/4; 15/64; 7/32; 13/64; 3/16; 11/64; 5/32; 9/64; 1/8; 7/64; 3/32; 5/64; 1/16.

Do the bits have a round shank or do they have 3 flats. i think milwaukee calls it secure grip.

3 flats. I'm sure the smallest bits are round but any bit that you can put some torque on has the flats.

Milwaukee Tools makes excellent drill bits. They seem to last a long time. Rarely need to sharpen the cutting flutes.

Drill like butter just as expected from Milwaukee. A bit difficult to remove bits from the index.
