anyone got any recommendations for decent quality drill bits?
metric up to 10mm for drilling normal car stuff, mainly mild steel, occasionally stainless steel, don't want to buy a set just a multiples of the smaller sizes which are the ones I tend to break more often.

By no means cheap, but they are amazing is the set I got from our Mac dealer. Facom manufactured, lifetime warranty if they go blunt or break, or even if they snap whilst in use The set goes from 1.5mm up to 13mm in 0.5mm increments, but it was 180quid for the set For the peace of mind warranty at work, worth every penny! And they cope very well with drilling stainless too

The only decent new drill bits I’ve bought for ages are Bosch. I tend to furtle round in junky places after old dormer, Presto and zebra, as they’re quality and actually resharpen unlike most new ones. but I bought a 10 box of new Bosch in a very snappable size (4mm iirc) and they’ve been great.

+1 for Bosch drill bits.
I bought a set of Bosch cobalt bits off ebay for about £34 and they've been great. The only one to break so far was the 7mm and that was thanks to my neighbour. It broke as he rushed the job of breaking back in to his own house after locking himself, his wife, their dogs and their house keys inside their house in the pouring rain haha.

I got a set of Presto's from RDG tools a few years ago, they have been fantastic but expensive so are used with care.

Not a word to swmbo but I've just bought a set of Norseman Vortex drill bits - based on a recommendation from Abom79.

Just buy a proper brand like dormer or presto and you cant go far wrong. I'd avoid pricey sets with fancy coatings or alloys unless you have a special job for them.
Theres no real benefit in buying coated drills for jobbing work. It's a gimmick that's come from the cnc machining world where cutting tools are used in a very controlled way and the coating can extend tool life. In a battery drill you will just wear through it straight away!
Cobalt alloys and the like can be a bit better for stainless and titanium but again I'd save them for controlled use in a drill press at least rather than forking out extra to use in a hand drill.
For 99% of work I'd just use bog standard phospated (black) HSS jobber bits.
Dormer do a great 1-6mm set btw. Think it's a 413 set. It's basically all the sizes that will get lost and broken and you don't have a spare from the last set you bought. I always keep a couple of fresh sets around.

Pretty much what the last two said.
Decent HSS and learn to sharpen them - or buy something to sharpen them in/with - even the crappy little powered drill sharpener from Aldi will do a semi-decent job for someone just wanting a drilled hole. Keep 'em sharp, let them cut, don't force them, and use cutting lubricant on just about everything.
And use the right speed - faster for smaller, slower, a lot slower, for larger.
You might be quite surprised how long a decent HSS jobber drill bit will then last.
