Who makes the best diamond drill bits? (DIY)

[LemonSunchines]

I want some really decent tiny drill bits, 2mm max. But I don't want them to wear out super fast. It's to fit a dremel for drilling thick glass. Any ideas?

Cooksons?

dremel's own? dewalt if they do that small

I used to work for a large hardware chain that catered for the general public but primarily the trade, the tradespeople generally favoured Dewalt drill bits, they cost a little more but we're acknowledged to be excellent quality.
