If you own a bobbin sander (you know, that drum attachment for your drill or bench sander), you know you go through these sleeves.

This Dapetz set gives you six sleeves in one handy pack.

The grit is 80, which is a good medium-coarse grit for shaping and smoothing wood, plastic, or even soft metals.

The sleeves come in six different diameters: 13mm, 19mm, 26mm, 38mm, 51mm, and 76mm.

That range covers most curve-sanding tasks, from tight inside corners to gentle outside curves.

They're made from aluminum oxide cloth spirally glued onto a cotton backing tube, which is the standard for these.

They're designed to fit standard 114mm tall (about 4.5-inch) bobbin sander drums.

They're consumables, so having a pack on hand means less downtime when one wears out.

Essential for any woodworker or DIYer doing detailed sanding on furniture, toys, or craft projects.
