What to do if my Grizzly Drill stalls or is underpowered?
- SStephen LongAug 12, 2025
If your Grizzly Drill is stalling or seems underpowered, consider these potential causes: the spindle speed might be incorrect for the task, the machine could be undersized, the bit or cutter might be dull, the power supply voltage could be low, or the belts might be slipping. Other possible reasons include a faulty plug or receptacle, incorrect motor wiring, a slipping pulley on the shaft, faulty motor bearings, an overheated motor, or a faulty motor. Decrease spindle speed, use smaller bits, check the power supply, replace belts, test the power plug, correct the motor wiring, replace the pulley and shaft if needed, rotate motor shaft for noisy or burnt bearings, clean the motor, and test, repair, or replace the motor if necessary.
