Dremel 670 Mini Saw Attachment – Circular Saw for Rotary Multi Tool
Product description
What it is
The Dremel 670 Mini Saw Attachment is a compact circular saw head designed for a rotary multi tool. It focuses on precision cuts in wood and wood-like materials, helping transform a versatile tool into a dedicated fine-cutting option without needing a full-sized saw.
What it does
This attachment enables narrow, straight cuts in wood and similar materials with a cutting depth of up to 6.4 mm. Its small footprint allows access to tight spaces and detail work that larger blades can’t reach. A transparent blade guard provides visibility while cutting, which is helpful for accuracy on delicate workpieces.
Why it matters
If you regularly tackle approach cuts, grooves, or detailed cuts in thin boards, laminates or wooden flooring, the 670 can be a convenient addition to your toolkit. On paper, it offers a practical way to extend a rotary tool into a cut-away system for lighter tasks where a full circular saw would be overkill.
What to consider before buying
The depth capability (6.4 mm) means it’s not intended for heavy-duty framing or thick stock. It’s best for precise, shallow cuts and trims rather than deep ripping. The overall usefulness depends on how often you need to make fine, narrow cuts in restricted spaces. If your typical tasks involve thicker materials or frequent long cuts, you may find it underperforms compared with a dedicated circular saw. Consider whether you already own a multi tool and how often you’ll switch to the 670 for detail work.
Pros and what to watch
- Pro: compact design suited for tight locations and fine cuts.
- Pro: transparent guard aids visibility and measured work.
- Con: limited cutting depth restricts use to thinner stock and detail work, not a substitute for a full-sized circular saw.
- Con: performance depends on the compatibility with your existing multi tool and blade alignment, ensure proper setup before use.
How it fits into real use
If you’re finishing laminate flooring or creating trim channels in thin plywood, this attachment can save time by letting you perform clean, straight cuts without swapping to a separate power tool. For hobbyists, it offers a pleasant way to experiment with precise cutting in small projects. If you’re after rugged, frequent, long-runs in hardwood, you might need to rely on other tools or blades.
Who it’s for
- DIYers responsible for finishing work in tight spots
- Light project enthusiasts who want cleaner, finer cuts than a typical rotary tool alone can offer
- Woodworkers who need a dedicated edge or trim cut without large machinery
Who it isn’t for
- Those who regularly cut thick stock or require deep cuts beyond 6.4 mm
- Users seeking a primary ripping or bulk-cutting tool
Before you buy
- Check that your multi tool is compatible with the Dremel 670 attachment and that you have suitable blade(s) for the material you plan to cut.
- Inspect the blade guard and ensure you follow safety guidance for small cutting tools.
- Think about your typical projects: if most cuts are deep or long, this may be a supplementary tool rather than a primary solution.
Alternatives and comparison in context
Compared with a full-sized circular saw, the 670 offers better access to constrained work areas and can handle detail work, but it cannot replace the depth and speed of a larger machine for thick boards. If your workflow involves frequent precise trimming on thin stock, this attachment can fill a niche without a big investment. If you mainly cut thicker materials, you’ll likely lean toward a dedicated circular saw or alternative tools designed for heavier cuts.
Final decision
Is it worth it?
It makes sense if you regularly work with thin wood, laminates or edges in tight spaces and you want to extend your multi tool’s capabilities for precise, shallow cuts. If you mostly need deeper cuts or heavy-duty ripping, it may not be the best fit.
