The 3M 7010309146 is a replacement disc pad face designed for use with 1-1/4 inch PSA (pressure-sensitive adhesive) sanding discs. Measuring 1.125 inches in diameter by 0.125 inches thick, this pad features a soft foam and vinyl construction bonded with VHB (Very High Bond) adhesive for secure, lasting attachment. The soft foam layer provides flexibility across the pad face, which helps reduce edge cuts when the operator tips the pad during sanding. It is a direct replacement for part number 50199 and is installed by technicians, finishers, and production sanding operators.
This pad face is suited for light sanding, finishing, and surface preparation tasks where a flexible pad backing is required to conform to curved or contoured surfaces. The compact 1.125-inch diameter makes it appropriate for detail work and tight areas. It is compatible with 1-1/4 inch PSA sanding discs in production and shop environments. Installation requires no special tools — the VHB adhesive backing bonds directly to the compatible pad holder.
Designed as a direct replacement for part number 50199. For use with 1-1/4 inch PSA sanding discs.
Installation is performed by hand with no special tools required. Clean the pad holder surface thoroughly before applying the VHB adhesive face to ensure a full, secure bond. Allow the adhesive to seat fully before beginning sanding operations. Dispose of worn pad faces according to local shop waste guidelines.
