I recently acquired a used Wen drill press. I used it to drill some small holes without any issues, but when I tried using a 1/2” bit I get a ton of chatter and as you can see in the video below the entire chuck fell out. This happened to me a few times even after cleaning the mating surfaces on the chuck and driving it back on. The drill seems to be spinning straight and I cannot see any wobble. Being that this is my first drill press I am unsure how to fix or troubleshoot the issue.

a couple things to determine is the bit sharp and was the speed correct for the bit used.

I used the guide in the pulley area to select the speed for the bit size in wood. I believe they recommended the highest speed. The bit, I am not 100% on that, maybe I need a bit sharpener.

How are you driving it back on? I usually raise the table up , stick a block of wood between and crank down the lever to press it in. I once had one that had a scratch that kept it from mating well. I had to use wet dry paper with 3 in 1 oil to sand it smooth.

Do not use lube on shaft, shaft must be cleaned and dry when installed, no slippery stuff !!!

Watch at 3 min and 30 sec into video,

I used a block of wood and a hammer to drive it back on. And I made sure the mating surfaces are clean and dry before doing so. the vibrations are what are causing it to come loose again.

I think it is either the bit (the tip looks funny when it first starts)

or it’s the music !!!!!!

Probably the music, but I am thinking the grinding isn’t the bit on the wood, but is the chuck itself spinning on the taper. If it’s falling apart, this makes sense as well.

Are you certain the stub, and the chuck are matched, and correct for the drill press?

I like that video the Old Bull posted, watch, and do exactly what they show. Generally “IF” the parts involved are correct, this is a quick, painless procedure.

Well since the drill press was purchased second hand I can not guarantee that the stub and the chuck are a matched pair.

That procedure in the video is pretty much the same as what I did. I did not completely remove the spindle from the drill press housing though.

Maybe I will pick up a drill sharpener and see if the bit is just too dull. Are the drill doctors good?

A properly sharpened bit will go thru that wood in a second or 2.
