Dremel Multipurpose Spiral Cutting Bit Multipack 561 (3.2 mm shank)

The essentials

If you do a fair bit of DIY, small repairs, or neat craft work, a decent spiral cutting bit can save you time. The Dremel Multipurpose Spiral Cutting Bit Multipack 561 is built for cutting and drilling in softer materials, with a design that’s intended to keep things controlled rather than messy.

On paper, this one is aimed at wood that isn’t too hard (the listing mentions softwood up to 12 mm thick), plus plastics and plasterboard. That makes it the kind of accessory you reach for when you’re making holes for fittings, doing straight-ish cuts, or working through sheet materials where you want the tool to behave.

What it’s for (and where it fits in)

The multipurpose spiral format is meant to handle both cutting and drilling tasks, which is useful when you don’t want to swap bits every five minutes. The listing also points to a specific pairing: using this bit with the Dremel multi-purpose cutting accessory 566 can help maintain cut depth during cutting and drilling.

It’s also designed to suit Dremel multi-purpose/rotary tools (and other compatible multi-purpose/rotary tools) that take a 3.2 mm collet/mandrel. That compatibility detail matters more than people think—if your tool’s chuck doesn’t match, this becomes a non-starter.

A practical example: imagine you’re fitting a small plastic wall component or tidying a cut-out in plasterboard. With the right depth approach and a steady hand, a spiral bit like this is the sort of attachment that helps you work cleanly rather than forcing the material.

The essentials in numbers (so you can judge fit)

This bit family is described with a work length up to 20 mm and a cutting diameter of 3.2 mm. That combination tends to suit smaller jobs and controlled cutting/drilling, rather than heavy-duty, deep drilling into tough stock.

The multipack format may be appealing if you like having spares or want options for the same general material type. That said, you’ll still want to keep expectations realistic: for harder materials, this is unlikely to be the bit you’d choose first.

What stands out day to day

The strongest selling point here is the intended material range. If your projects mostly involve softwood, plastic, or plasterboard, this multipurpose spiral bit makes sense because it’s targeted rather than generic.

It also comes with a clear usage recommendation. The note about the Dremel cutting accessory 566 is helpful—if you’re doing repeated cuts where depth consistency matters, that guidance suggests a more deliberate setup than simply “drill and hope”.

Limitations to consider before buying

Ten times out of ten, the catch with bits like this is material type and depth. You’re working with a listing that explicitly calls out softer materials, including softwood up to 12 mm thick. If your DIY usually involves hardwood, metal, or thicker sections, you may find this falls more into the “everyday soft-material jobs” category.

Also, while it adapts to compatible tools with a 3.2 mm mandrel, the wording doesn’t cover every rotary tool on the market. It’s worth double-checking your tool’s collet/shank requirement rather than assuming everything fits.

How to get the most from it

To get the cleanest results, treat this as a depth-and-control accessory. The listing’s mention of using it with the Dremel 566 cutting attachment is a hint that maintaining consistent depth can be a big part of getting good cuts.

If you’re drilling, start gently and let the spiral do the work—pushing too hard on softer materials can still lead to rough edges. For cutting, think about workholding and support, particularly with plasterboard and plastics, where excess vibration can make things untidy.

Mini FAQ

Is this bit mainly for cutting or drilling?

It’s described as designed for both cutting and drilling in softer materials, so it’s intended to cover mixed small tasks rather than being a single-purpose attachment.

What materials is the 561 best suited to?

The listing specifically mentions softwood (up to 12 mm thickness), plastic and plasterboard.

What size is the cutting diameter?

The cutting diameter is listed as 3.2 mm.

Does it fit all Dremel rotary tools?

It’s stated to adapt to Dremel multi-purpose/rotary tools (and other compatible multi-purpose/rotary tools) with a 3.2 mm mandrel. If your tool uses a different collet size, you should check compatibility first.

Is it worth it?

Worth buying if your projects mostly involve softwood, plastic, or plasterboard, and you want a spiral multipurpose bit that’s made for smaller, controlled cutting/drilling jobs with a 3.2 mm setup. It also makes sense if you like having spares in a multipack.

It’s not the best choice if you regularly tackle harder materials, deep cuts, or thick stock beyond what the listing suggests. And if you’re not sure your rotary tool’s mandrel/collet is 3.2 mm, pause before ordering—compatibility is the one thing here you can’t “make work” safely.
