Q: Would these be ok for a lintel above a window

They will but you have to remember all lintels have reinforcing bars through then . If modern these bars will be 50mm from top and bottom so you need to drill to avoid them . Masonry drills will not drill steel.

Q: Are these suitable for drilling holes into ceramic plant pots?

Yes without a doubt. I found these the most versatile bits I've ever owned. I used them to drill through ceramic wall tiles and then straight on through a concrete wall that is notorious for killing drill bits several holes later it still looks good. In my opinion you will not buy anything else after using these.

Q: Are these definitely cobalt? Suitable for drilling stainless Steel as the back of blue packet they are packed in says wood & plastic

I have used the drills on stainless steel 1.5mm thick at a medium speed and plenty of coolant and found the result very good they seem to be very good quality for the price, i have used them most on plate steel up to 12mm thick with excellent results, as for them being cobalt i don't know !
