I just bought the 8 inch 5 speed drill press from harbor freight with a 2.4amp motor.
I am running about 3000 rpm and I’m having a problem drilling 1 5/8” holes with fornestor bits. The bit just stops turnimy. Am I doing something wrong or is the motor just not powerfully enough?

I would slow it down quite a bit. Check out this chart for reference:

Thank you guys for the tip.

The motors on smaller power tools are often undersized. I have a cheap 9” bandsaw that I can easily stall the motor with just a slight push on the wood. The motor slows down and this is my hint to back off the pressure. You may be able to notice the same thing with your drill press. Lighten up the handle pressure and the motor should start turning again. Changing the belts on a drill press gives you a mechanical advantage of more torque at lower RPMs.
