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:

I slowed my press to about 700 rpm and the bit went through like butter
Thank you guys for the tip.
I truly appreciate it.

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.

I took the tips,from the replies I got and I lowered the rpm to about 700 and the fornester bit drilled like a charm.
