For drilling in metal, my 'go-to' HSS bits are B&D Piranha Bullet Drills (made in Germany). From 3mm upwards they have a pilot tip, they do NOT wander at all and cut really well in most materials.Can anyone recommend a good quality make?
Thanks.
I use the very fine Heller ones (0.2 mm For example) for watchmaking, and find them very good. They cut well but also seem to be a little more flexible so don't break as easily. But agree with the comments about Dormer, expensive but very good.Another one for Dormer. I also use Heller for wood/plastics etc, not had the nerve to use on steel dont know how they'll cut, probably ok actually. Also use Brad Point twist drills from Wealden, excellent quality I think theyre Austrian (Alpine? brand)

Keep an eye out on eBay as sets of 1mm to 10mm (in 0.5mm increments) come up occasionally ...
