S SATC 125mm Orbital Sander Sanding Discs (100 grit) – 110 Hook & Loop Pads for Random Orbital Sanders

The essentials

If you’re sanding by hand, it’s amazing how quickly you can end up with uneven patches or clogged sheets. These S SATC sanding discs are designed to snap onto a 125mm random orbital sander using hook-and-loop fastening, so the pad change is straightforward and the disc stays put once fitted.

On paper, the focus here is medium 100 grit for woodworking and more detailed work like removing paint or coating. That “middle” grit is often where people land when they want a smoother finish than coarse sanding, but still need real cutting power rather than just refining.

Key points that matter before you buy

What stands out is the combination of a 100 grit medium abrasive and an open-coated surface. The open coating is meant to support consistent dust removal, which in turn helps reduce sheet clogging. That’s useful if you’re sanding coated surfaces or working through wood where dust build-up can otherwise slow things down.

The discs are made from tough aluminium oxide abrasive. Again, that’s a sensible choice for repeated use, even if you’re not expecting “miracle longevity” in every situation—how long they last depends a lot on the material and how aggressively you sand.

You also get 110 discs, which is the kind of quantity that makes sense for regular DIY jobs, small workshops, or anyone who simply likes having replacements ready.

What you’ll notice in use

Hook-and-loop discs are convenient, but only if they actually grip reliably. The product description claims the hooks and loops stick well to the sander pad and shouldn’t slip once attached. In practical terms, that matters because a disc that shifts slightly can leave streaks or a patchy surface.

A quick example: if you’re preparing a door panel after removing an old coating, you can run through a sanding pass with 100 grit to level things out, then move on to a finer stage for the final smoothness. With open coating, the dust load should stay more manageable, so the disc keeps working rather than going “glossy” from trapped debris.

One limitation to keep in mind: 100 grit is medium. If you’re stripping heavily or need aggressive material removal, you may still want a coarser grit first.
