Just use ordinary drills from hardware stores; they are so cheap in HK. Unless you are proeducing en mass. Carbide ones are not cheap even in Ap Liu.

I have tried normal HSS drills and it doesnt work. Maybe I can get 2 - 3 decent holes before the holes start to look more like craters then holes and the copper is ripped apart from the laminate.

I don't have that problem with drills bought in Hong Kong. What are you drilling and have you the right speed?

Some HSS drills bought in UK are crap.

I have used a Bench drill press at the highest speed it
can 2800 rpm. Do I have to use a higher speed with the HSS drills ?
The HSC drills are so fragile so thats why I need some new ones in sweden they are redicolusly expensive. I have seen in china a long time ago HSC drills for about 1,5 EUR a piece!
