Dormer drills are quite good.
Cobalt drills are better if you want to pay the extra for them.
Using a good quality cutting fluid or oil will make them cut better and last longer.
If you are after any larger drills from maybe 10 to 20mm I will have a few morse taper ones for sale in a short while when I sort out my new workshop.
Also keep the speed of the drill down, helps the cut and extends the life of the drill bit.
