Rather than wadding or rolling up a scrap of sandpaper to get into a tight space, you might want to look at Sandits, which are flexible double-ended sanding sticks that are tipped with two different grits. Sandits can reach into corners, grooves, crevices, and other places your sandpaper just can’t go.
Don’t mistake these for cotton swabs, or you’ll be sorry!
Orion Product Group manufactures Sandits in China by bonding either aluminum oxide or silicon oxide abrasive grit to 6″ sticks with marine-grade epoxy. Besides making the Sandits waterproof, the materials used are also non-conductive.
The manufacturer recommends Sandits for use in jewelry making, automotive painting and chroming applications, boating materials such as fiberglass, teak, and chrome, and for fine-finishing on wood, plastics, and metal materials.
They also say that these can be used anyplace you need scratch-free polishing, smoothing, and finishing, although we would urge caution before you attempt to use these or any other abrasives on delicate surfaces.
Sandits come in two basic shapes: the standard rounded tip and a tapered wedge-shaped tip, which I think looks more like a thin coffin shape.
The standard round-tip Sandits come with 120 and 180 grit tips (on opposite sides) and are sold in packs of ten. The very fine/extra fine round-tip Sandits have 400 and 800 grit tips and are sold in packs of 8.
The wedge-shaped Sandits have 120 and 180 grit tips, and are also sold in packs of 8.
Sandits are available via Rockler, and also through the manufacturer’s own online store. They’re about $7 per pack, plus shipping, and if you order through the manufacturer they offer a bulk discount if you order 4 or more packs of the same type.
If you are the type of person that likes to get your hands on a product before you buy, Sandits should are be available Rockler brick and mortar stores, and possibly other woodworking suppliers.
While I’m not sure I have an immediate use for Sandits, They are definitely something I’ll keep in mind next time I need to do some detail sanding
