Sanding Pads for Internal and Irregular Surfaces
Sand inside pipes and tubes as well as on an angle to reach into corners and slots. A shank adapter is required (sold separately).
Square pads sand quickly and won't leave swirl marks because of the alternating stroke of the pad corners.

Nylon Mesh Cushioned Sanding Pads for Internal and Irregular Surfaces
The abrasive-embedded mesh construction gives you more control over sanding pressure, creating finer and more consistent finishes. These pads sand inside pipes and tubes as well as on an angle to reach into corners and slots. A shank adapter is required (sold separately).
Medium grade is for light cleaning and blending.
Very fine grade is for finishing.
