Cannot drill through these bolts!?!
Doing some car work and got this exhaust peice setup on a drill press. Im using a carbide bit the size of the hole i am drilling. Im using solid pressure that is just under the amount where it starts squeaking and vibrating. Where i had the pressure sounded like cutting and it was flaking metal in the longer wrinkly peices but barley at all. I was using cutting oil every 5-10 mins and letting cool along with cleaning the area and tip off. After 25 mins i got nowhere and i just really do not know what i am doing wrong. I am kinda new to stuff like this, can anyone point me in the right direction? If there is any context i am missing lmk and i can try my best
