drilling problem
Hi. I did with cnc machine smaller hole before, now i want to drill 6mm hole with hand drill, but i don't understand why i can't drill through the metal.
Metal is S235 or maybe S355. I bought new different drill bits. But drill bit just spinning in hole but doesen't drilling. Any of these drill bit's do nothing.
I use low speed and wd40. Not coming good chips/swarfs but only like powder. (metal thickness what i want to drill is 3mm)
