DREMEL 670 Mini Circular Saw Attachment with 6.4 mm Cutting Depth

For DIY jobs that call for fine, straight cuts in wood or laminate, the DREMEL 670 adds a compact circular saw attachment to a Dremel multi-tool.

Its stated cutting depth is up to 6.4 mm, making it suited to shallow cuts rather than work that needs a deeper saw.

A transparent blade guard and compact form are useful details for careful cutting in confined spaces. The attachment comes with a saw blade accessory.

What to know

The DREMEL 670 is intended for straight cuts in wood and wood-like materials, including laminate. That makes it relevant to detailed flooring work, small DIY projects and model-making, where a full-size circular saw may be awkward to position. The description also mentions plunge cuts, while the product specifications list bevel capability.

Depth is the key buying consideration. The product details give a maximum of 6.4 mm, while the description specifies 6.35 mm at 90°. Either way, this is a shallow-cut attachment, it is not a substitute for a saw chosen for thicker timber. The blade size is 31.8 mm, and the attachment has a bevelled base designed to help keep the multi-tool body clear while cutting.

The supplied parts are the DREMEL 670 circular saw attachment and a 546 saw blade accessory. Its listed dimensions are 5.9L x 3.7W x 2.4H centimetres. These details help set expectations for a small accessory rather than a standalone saw.

Everyday use

The transparent guard gives a view of the blade while helping to shield it during cutting. Its compact size is intended to make access easier in small or awkward areas, which can matter when trimming flooring or working on a craft piece. As it is an attachment, the intended setup is a Dremel multi-tool, the supplied information does not identify specific compatible tool models, so check fit for your own tool before choosing it.

Buyer feedback is generally positive about the attachment’s quality and how it performs. Opinions on cut depth are more mixed: some buyers say it cuts well, while another notes that the depth is limited. That difference is worth bearing in mind, as the stated maximum is shallow by design rather than a measure of suitability for every sawing task.

Best use cases

This attachment makes most sense for controlled, fine cuts in wood, laminate and similar materials, especially where a larger saw would be cumbersome. A flooring adjustment, a small straight cut on a wooden craft project or a plunge cut for model-making are examples of the kind of work described for it. The transparent guard and compact format suit close, detailed work, while the blade’s listed depth keeps the task within a narrow range.

You’ll like it if you already use a compatible Dremel multi-tool and want a compact way to make shallow straight cuts. Not the best choice if the job involves thick material or needs the reach and cutting depth of a full-size circular saw, that more demanding work calls for a different tool.

Is it worth it?

The DREMEL 670 is a focused accessory, not an all-purpose saw. Its case is strongest when portability and access to a small work area matter more than cutting depth. For laminate or wood projects that stay within the stated depth, it offers a more compact approach than bringing in a larger saw, and the supplied 546 blade means a blade accessory is included. If the planned cuts exceed roughly 6.4 mm, or the work needs a broader range of sawing capacity, choose a tool designed for that instead.
