Dremel 660 Router Bit Set (7-piece) for 3.2 mm shank rotary tools
Product description
If you do more than one kind of routing job, a mixed router bit set usually saves you time (and faffing about) compared with buying individual profiles. The Dremel 660 set is aimed at getting you from straight cuts to more shaped edges, with seven multipurpose profiles stored in a compact wooden box.
On paper, it’s a neat starter bundle for small-scale workshop routing, especially if you already use Dremel-style rotary tools with a 3.2 mm shank. It’s not the sort of kit you buy if you need specialist, production-grade tooling for heavy-duty cabinetry every day, but for DIY and light professional use, it can be a practical way to cover common routing tasks.
At a glance
This is a 7-bit router bit set for routing applications, covering a range of common profiles such as edge and corner routing, straight routing, keyhole routing, and word/letter routing. The idea is straightforward: swap the bit to match the shape you’re trying to cut, rather than relying on one profile for everything.
The included wooden storage box is also more useful than it sounds. Bits are easy to misplace, and having a compact box tends to keep things together when you’re working across projects.
What you’ll notice day to day
In everyday use, the biggest “value” of a set like this is flexibility. For example, you might start a project by trimming an edge for a cleaner finish, then change to a different profile for a corner detail, and later switch again for letter or word routing. That kind of workflow is where multipurpose sets tend to feel worth it.
The set is described as suitable for routing in a variety of materials including wood, rubber, plastic, carbon, and fibreboard. That breadth is helpful if your workshop isn’t limited to timber alone. Still, it may be worth remembering that material capability can depend a lot on your speed, technique, and what exact job you’re attempting—no bit set is magic on its own.
Also, for more precision and control, the base description specifically points to pairing with the Dremel 335 Plunge Router Attachment and the Dremel 231 Table Router. If you already have those accessories, this kit fits the way a proper routing setup is meant to be used. If you don’t, you’ll still be able to use compatible 3.2 mm shank rotary tools, but your results may be more dependent on how steady you can be.
Key features
What matters most here is the mix of router bit profiles. The set includes seven different profiles intended for different routing applications, including:
- Edge and corner routing
- Straight routing
- Keyhole routing
- Word and letter routing
The other standout feature is compatibility by shank size. The description states it fits with Dremel Multi-/Rotary tools or other multi-/rotary tools that use a 3.2 mm shank. That’s a key detail to check before ordering, because shank size mismatches are an easy way to end up with bits you can’t use.

Who it’s for (and who should skip it)
It makes sense if you want a compact way to handle common routing tasks—especially edge/corner shaping, straight cuts, and basic keyhole/letter-style routing—without needing to buy separate bits for every profile.
It might not suit you if you’re expecting a single kit to replace more specialist routing solutions for complex, high-demand work. Also, if your current rotary tools do not take a 3.2 mm shank, you’ll need to rethink compatibility before investing.
Worth noting that this set is positioned as a practical multipack rather than a deep “every possible profile” collection. If your projects consistently need very specific shapes, you may still end up adding individual bits later.
Should you buy it?
Buy it if you already work with 3.2 mm shank rotary tools and you want a straightforward set of profiles for everyday routing jobs—edges, corners, straight lines, and occasional keyhole or letter/word routing. The wooden box is a small detail that can genuinely improve day-to-day organisation.
Don’t buy it if shank size compatibility is unclear for your tools, or if you’re after highly specialised routing outcomes where one set of multipurpose profiles may feel limiting. In short: it’s a handy, mixed-profile bundle for typical workshop routing, not a replacement for a full, job-specific tooling lineup.
