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

    What causes excessive deflection in the quill of my Grizzly Drill?
    • M
      Mr. Michael ComptonAug 23, 2025
      Excessive deflection in the quill of your Grizzly Drill can stem from a couple of issues. First, the quill bearings might be worn or damaged, requiring replacement. Alternatively, the quill shaft itself could be faulty, necessitating its replacement.

    Why is my Grizzly Drill vibrating so much and making noise?
    • M
      Michael KellyOct 29, 2025
      If your Grizzly Drill vibrates excessively or is unusually noisy, several factors could be the cause. It might be due to the motor fan rubbing against the fan cover, which can be resolved by replacing or repairing the dented fan cover and replacing any loose or damaged fan. A loose motor or component can also cause vibration; in this case, replace the component fasteners and re-tighten them with thread-locking fluid. Additionally, the belt slapping against the belt housing, a worn V-belt, or a loose pulley can contribute to the issue. Replace, realign, or re-tension the belt, replace the belt if worn, and securely reinstall the pulley, replacing the key if required. Incorrect mounting of the machine to the stand, the stand to the floor, or an uneven stand can also cause vibration; ensure t...
