Makita 122548-3 Dust Bag Assembly is a replacement dust collection accessory for select Makita belt sanders. This is a dust bag assembly designed for collecting sanding dust during belt sander use. Model Number: 122548-3. If your original bag is torn, worn out, or missing, this part gives you a straightforward way to get your sander back to cleaner operation.

What matters here is simple: belt sanders throw a lot of fine dust, and a working bag helps keep that mess from ending up all over the workpiece, the bench, and the room. Makita states this accessory is engineered to hold a significant amount of dust, so you can sand longer before stopping to empty it. That is especially useful on repeated passes where stopping every few minutes gets old fast.

This dust bag assembly is built for quick install and easy removal. That is the kind of feature that sounds small until you are actually using it. When a bag comes off easily, you are more likely to empty it when you should instead of overfilling it and cutting collection performance. For routine sanding work, that convenience is worth having.

Makita also calls out high quality materials for added durability and longer life. On an accessory like this, that matters because it gets handled, removed, emptied, and reinstalled over and over. A flimsy bag becomes a hassle fast. A better-built replacement part keeps the tool working the way it should without turning dust collection into the weak link.

As a product category, this is a belt sander accessory, not a universal dust collector bag. It is intended for dust collection at the tool during sanding applications. That makes it a good fit for users who want to maintain original-style dust collection on a Makita sander instead of rigging up a workaround.

This part makes the most sense for owners of compatible Makita belt sanders who need a direct replacement bag assembly for day-to-day sanding in woodshops, garages, and jobsite touch-up work. If you already have the right sander and just need the correct bag back on the tool, this is the simple fix.
