The Best Multi-Purpose Sander for Contoured Surfaces: Sand-O-Flex

Stop Hand-Sanding Irregular Curves. Let the Sand-O-Flex Do the Work.

The Sand-O-Flex is the ultimate solution for woodworkers, metal finishers, and DIYers who struggle with intricate shapes. By combining eight abrasive cloth flaps with cushioning brushes, this tool acts like hundreds of flexible fingers that reach into crevices and contours where traditional sanders fail.

Why Sand-O-Flex is the Professional’s Choice

• Follows Every Curve: The flexible fingers adapt to irregular surfaces, eliminating the risk of flattening out your detail work.

• Constant Refresh: A simple turn of the knob feeds out fresh abrasive strips instantly. No more stopping to change pads every five minutes.

• Lightweight & Versatile: The durable plastic unit attaches easily to your standard hand-held drill or rotary tool.

• Bench Motor Compatible: With our Adapter Collar, you can mount the unit directly to a 1/2" smooth shaft bench motor (Max 2400 RPM).

• Resin Bond (Stiffer): Best for heavy material removal and durability. Available in 60, 80, 100, 120, and 180 Grit.

• Glue Bond (More Flexible): Best for fine finishing and delicate contours. Available in all grits from 60 to 320.
