No. To me a larger cog with a worm gear puts little wear on the item. Plastic may actually work better at this price point than what may be ill fitting pot metal. Have you had issues with the adjustments on your grinder? I've had none. Much better to adjust than my Compak but that's perhaps not saying much.
