Sanding Pads for Internal and Irregular Surfaces
Sand inside pipes, tubes, and hard to reach corners with these pads. A shank adapter is required (sold separately). The most common abrasive material, aluminum oxide is hard enough to sand steel and wood.
Cross pads allow you to see through the pad when in motion to better control material removal.

Sanding Pads for Internal and Irregular
Surfaces on Stainless Steel and Hard Metals
The ceramic alumina abrasive on these pads is sharp and dense enough to shape hard metals such as stainless steel, nickel, and iron without dulling quickly. They’re often used to sand inside pipes and tubes, or to sand at an angle when reaching into corners and slots. The abrasive material on these pads continuously fractures to produce new, sharp cutting edges. They sand faster and last longer than aluminum oxide but require more force to abrade properly. A shank adapter (sold separately) is required.
Cross pads allow you to see through the pad when in motion to better control material removal.

Arbors for Sanding Pads for Internal and Irregular Surfaces
Also known as cross- and square-sanding pad shank adapters, these arbors are required to attach sanding pads for internal and irregular surfaces to hand-held drills and die grinders. Arbors are also known as mandrels.
