3M™ Finesse-it™ Wetordry™ Scallop Abrasive Disc 401Q is small but mighty: its overall diameter measures 1-3/8 inches. The small size lends itself to buffing, polishing and finishing on small surfaces – those areas where a tiny ding, scratch or imperfection can make all the difference.

The Science Behind Disc 401Q
We engineer our 3M™ Finesse-it™ Wetordry™ Scallop Abrasive Disc 401Q with silicon carbide mineral, which is adhered to an A-weight paper backing. A synthetic mineral, silicon carbide cuts sharp but leaves a bright finish. Its ability to finish fine is one of the primary reasons we chose this mineral for disc 401Q. The A-weight paper backing is the lightest among paper backings. This backing is desirable, because – given its lightness and malleability – it will respond well to the surface without significantly gouging or marring.

Additionally, disc 401Q has a pressure-sensitive adhesive backing, which means it adheres to a backup pad (sold separately) with slight manual pressure. Removing the disc is as simple as securing it – simply peel it away from the backup pad. Altogether, this attachment system expedites tool connections. It makes disc changeouts fast and easy, so you can focus on what matters most: your work.

The scalloped edge on disc 401Q adds a level of surface forgiveness that operators may otherwise be unable to attain with standard round discs. Because the edges are scalloped, if the disc accidentally tilts or abrades with its edge, it will be more forgiving than if it were a rounded edge. In this way, the risk of gouging or over cutting is reduced.
