PREPPING YOUR BIT

Apply a small amount of petroleum jelly to your grinder’s motor shaft and set screw before installing the bit. The petroleum jelly will prevent glass powder from impacting in the bit cylinder shaft and making the bit difficult to remove for replacement and cleaning.

To remove any surface residue from the manufacturing process, attach your bit and turn the grinder on. With a piece of scrap glass grind up and down the bit 3 or 4 times.
