MK Diamond 7" Hard Rubber Backplate Disc with 5/8" - 11 Nut, 155968

The MK Diamond 155968 is a 7 inch hard rubber backplate disc with a 5/8 inch to 11 threaded nut. It threads directly onto an angle grinder spindle and carries the polishing or sanding pad, with the hard rubber body setting how flat that pad sits against the work.

📊 AI MARKET SNAPSHOT

• Best For: Concrete and stone crews running 7 inch polishing or sanding pads on a threaded 5/8 inch to 11 grinder spindle.

• Highlight: The hard rubber durometer holds a flatter profile than a foam backer, which is what surface-prep work on concrete and stone needs.

• Expert Note: Match the 7 inch backer to a 7 inch pad - an overhanging pad edge on a hard backer digs in and leaves swirl marks a softer foam backer would have absorbed.
