3M Scotch-Brite Unitized Deburring Wheels - 2 A - Med/Hard - 6" x ½" x ½"

The "2A" designation on this 6.0-inch wheel indicates a "Medium Hard" density, providing a more aggressive and stable abrasive action than the softer SFN versions. This wheel is perfect for heavy-duty deburring and the removal of stubborn casting lines on thick jewelry pieces and metal findings.

The increased hardness allows the jeweler to apply more pressure without the wheel collapsing, which is essential for leveling flat planes with high accuracy. It is a durable, high-speed solution that bridges the gap between rough grinding and the final stages of pre-polishing in a professional workshop.
