61 customers mention55 positive6 negative

Customers are satisfied with the speed control of the disc grinder. They mention that the adjustment is smooth and uneventful. The variable speed is great for buffing wheels and has a good range of speeds. The grinder runs smoothly and comes up to speed quickly. The ability to knock the speed down is useful for not ruining the temper as easily. The tool is versatile and can be used for various leather thicknesses and grits of sandpaper. It is hard to believe that it is running.

If your Delta comes with a bad vibration out of the box, the flanges on the side of each wheel may be out of alignment with the wheels. My flanges had fused to the printed side of the wheel stickers out of the factory—manufacturing issue? You’ll see what I mean if you try to remove the flanges from the wheels. Try these steps below and your vibration will decrease significantly.Step 1: buy Delta bench grinderStep 2: assembleStep 3: remove side wheel coversStep 4: remove the wheel nut on each side—one is reverse threadedStep 5: remove wheels w/ flanges from spindleStep 6: remove the four flanges (two per wheel) with a screw driver—do not pound on wheelsStep 7: return the flanges to their respective wheels, and swap wheels left-to-right, right-to-left back on the grinderStep 8: return wheel nuts to the spindle, and only hand tightenStep 9: replace wheel coversStep 10: turn on grinder—no more vibration issues!!!Step 11: grind a bunch of metal stuff and replace the factory wheels ASAP with something halfway decentOh, and if the light keeps moving around, you can remove the plastic bottom plate of the grinder base, and tighten the lamp neck washer from the inside of the unit’s base. You will need two wrenches and a Phillips head.
