Dremel 684 Cleaning and Polishing Kit (20 accessories) for 3.2mm rotary tools
Product description
If you do small jobs around the home workshop, a cleaning and polishing accessory set can save a lot of messing about. The Dremel 684 Cleaning and Polishing Kit is built around rotary multi tools and comes with a selection of accessories plus two mandrels, so you can move from cleaning to polishing without hunting for extras.
That said, it’s a kit for getting through everyday workshop tasks rather than a substitute for proper surface finishing systems. On paper, it looks like a handy “in-between” option when you want visible improvement but don’t want to build a full dedicated polishing setup.
What it is and what it’s for
The Dremel 684 kit is a multi-purpose accessory set designed for cleaning and polishing with rotary multi tools. It’s intended for use on a range of materials, including metals like copper, silver, gold, stainless steel, hardened steel, aluminium, brass, sheet metal and cast iron. The kit also states it can be used on plastic and glass fibre reinforced plastics.
In practical terms, it’s the kind of thing you’d reach for when you want to refresh metal surfaces, tidy up marks before a finishing step, or polish small parts where hand tools would take ages. Imagine cleaning up tarnish on a small brass component, then switching to polishing to bring back a more uniform shine.
Where it stands out
What makes this kit feel useful is the combination of cleaning and polishing accessories in one box, plus two mandrels for mounting. Having mandrels included matters because it removes a common “why can’t I fit this?” moment that can happen when you buy accessories separately.
It also comes in a convenient toolbox, which is more than just packaging. For a set like this, you want accessories to stay organised and protected, especially if you regularly swap between different bits.
Finally, the kit is described as fitting all Dremel Multi-/Rotary tools or other multi-/rotary tools with a 3.2mm shank size. That compatibility point is often the difference between a kit that’s reassuringly versatile and one that becomes a box of bits you can’t use.
The essentials (compatibility and use)
This is aimed at people who already own a rotary multi tool and want a ready-made accessory bundle for metal (and some plastics). Because the instructions say it’s for 3.2mm shank size tools, you’ll want to double-check your tool’s shank size before committing.
It’s not perfect in the sense that the kit won’t cover every possible finishing scenario. If you’re expecting mirror-level results on highly contoured workpieces, you may find you still need additional sanding stages, specialist polishing compounds, or more aggressive approaches.
Worth considering if you mainly do small-scale cleaning, deburring, and polishing rather than heavy-duty refurbishment.
What you’ll notice day to day
In everyday use, kits like this tend to reward patients more than force. Over-pressing can dull the finish or leave uneven results, especially on softer metals. So it’s best treated as a controlled process: short work sessions, checking progress frequently, and switching accessories when the surface starts to look “right” rather than pushing until it’s visibly perfect.
Also, because it spans both cleaning and polishing, it can reduce the number of tools you keep on the bench. That’s genuinely useful when your time is limited and you’re tackling lots of smaller tasks.
Who it suits, and who should think twice
It makes sense if you already own a Dremel multi/rotary tool (or another 3.2mm shank tool) and you want a compact way to handle cleaning and polishing across common materials like copper, brass, aluminium or stainless steel.
It might not be a great match if you don’t have a compatible 3.2mm shank rotary tool, or if you’re trying to achieve a very specific high-end finish that depends on exact compounds and progressive grit systems. Ten minutes with the wrong accessory can look worse than leaving the workpiece alone.

Is it worth it?
Buying the Dremel 684 Cleaning and Polishing Kit is worth it if you want one box of mixed cleaning and polishing accessories for common metal (and some plastic) tasks, and you’re confident your rotary tool uses a 3.2mm shank size.
You may want to skip it if you’re starting from scratch with no compatible rotary tool, or if your goal is ultra-specific, professional-grade finishing where choice of exact polishing stages matters more than convenience.
When it makes sense, it’s the kind of “grab-and-go” kit that fills the gap between basic cleaning and more involved finishing work.
