3M Lite Deburring & Finishing Wheel - 9S FIN

This 9S density wheel is slightly harder than the 7S version, offering a more aggressive cutting action for tougher finishing jobs. It is particularly effective for removing more stubborn burrs and smoothing out larger surface areas on heavy jewelry pieces or flat-backed pendants.

Despite its increased hardness, the wheel remains "smear-resistant," ensuring that it does not leave unwanted residue on the precious metal surface during high-speed rotation. This is a durable, professional-grade tool that helps maintain the geometric integrity of the jewelry while preparing it for a deep, high-luster polish.
