What to do if my Grizzly G9749 Drill stops drilling but the motor is still running?

  Kelly LeonAug 5, 2025
  If your Grizzly Drill stops drilling while the motor continues to run, this could be due to several reasons. First, check the belt, as a loose, worn, or broken belt can cause this issue. In this case, you should replace, realign, or re-tension the belt. Another potential cause is the bit slipping in the chuck. To resolve this, tighten the bit and inspect it for any burrs or obstructions that might interfere with the clamping surface. Finally, the pulley might be slipping on the shaft, which would require you to remount or replace the pulley and shaft.

Why does the chuck on my Grizzly Drill wobble or feel loose?

  If the chuck on your Grizzly Drill wobbles or feels loose on the spindle shaft, it could be due to a couple of reasons. Foreign material might be stuck between the chuck-to-spindle mating surface. To fix this, remove the chuck, clean, and de-burr the tapered chuck and spindle mating surfaces, then reassemble it. Alternatively, the chuck itself may be damaged and require replacement.

Why won't the spindle on my Grizzly Drill retract fully or why is it binding?
- G
  Guy ThomasAug 17, 2025
  If the spindle on your Grizzly Drill does not fully retract to the uppermost position or if it binds, there are a few possible causes. The quill shaft might be gummy due to sawdust and oil accumulation. To resolve this, clean the shaft and lubricate it with a light coat of oil. Another cause could be that the quill lock is engaged or not fully released, so ensure that you fully release the quill lock. Lastly, a weak feed shaft return spring could be the problem, and in this case, you should replace the feed shaft return spring.
