I need to make some ø13mm holes right through (l=72mm).material is 1.4980/660. It's a bleeding hell drilling this stuff.
I prefere a supplier in europe/denmark
any help is appreciatet

What type of machine and stock are you using we need more infor what RPM is the machine max. and what type of drill

In fact I'm asking for a former woorkmate.
I know the matrial and ther's 400 of them.It's to be done at a (older) Mazak bench.
Can't remember max rpm, about 4000
>>just got confermation 4000 rpm max<<
I need to know which type off drill that would be best buy

try this like for free soft wear for your feeds and speeds and the size of the drill this should help get you close start slow and try faster and you have luck I have drilled in all types of SS and you should not have any problem but the right drill will make life easer
