While using a 1 3/4” hole saw on my new Mexican drill press, I heard a loud noise and the bit stopped turning. I had forgotten to reduce the speed for this bit, which was set at about 1400 rpm. I tried a 1/4 ” brad point bit and had the same problem. The bit just stopped turning after initially biting in. The belts are fine, no slippage. The motor is running fine. The morse taper is clean. I’ll probably have to find a mechanic to look at the insides, but thought someone here might know what’s going on.

Maybe a shear key on the pulleys? The friction of the shaft wiould probably allow the pulley to turn until there is a load of some kind.

You need to unplug it, take the cover off and see if the key on the pulleys has sheared. Give us a brand and part # to look up the repair info. if you do not have the manual.

Thank you for making me take another look at the pulleys. I think the problem is solved: the retaining nut on the spindle pulley had fallen off. After tightening it, the drill press is working now. I hope it stays that way. I would have posted the brand and part #, but it’s a Mexican make (Surtek, 3/4 hp, bench model) and I can’t find any good info online.
