Dremel 670 Mini Saw Rotary Tool Attachment

This attachment fills a niche in my tool box. I wanted a rotary saw for cutting thin (1/8") acrylic and other plastic and wood. The saw cuts quickly through the material and leaves a smooth edge. It works much better than scoring and breaking the plastic using a scoring knife. For plastic it is much quicker than using a hacksaw or jeweler's saw and produces a straighter and smoother cut. For thin wood I find it easier and more efficient than using fine toothed hand saws for long, straight cuts. I have not had any trouble adjusting to using the blade guard or seeing the guide line and kerf through the clear plastic housing. It cuts a thin kerf. It is not a heavy duty cutting tool. Several reviews have down graded the attachment because it does not work well on hard and thick (1/4") material. This is useful information for setting it's upper limits, but it seems to clear to me that the tool was not made for these applications. I have an old Mikata cordless rotary saw and hacksaw, which I use on that type of material. This saw attachment is the lower (fine, light duty) end-member of a continuum of power saws in my tool box where the large circular and reciprocating saws are the upper (heavy duty, rough work) end-member. I see many reviews that downgrade an item because it did not perform well for a function it was not designed for. Buy and use the right tool for the job. This tool is light duty; that's evident from looking at the illustration. Clearly, it is not designed for use every day by a professional installing floors, etc. It's best use is for a hobbyist and for light duty cutting in thin material. By the way, the first package I received did not contain the drive adapter and the saw blade screw. I returned it to Amazon (they make returns easy) and they sent within two days a replacement. The replacement also did not have those two items. I called Dremel customer service and they were very courteous and helpful sending the drive adapter and screw at no cost, which I received in about three days of placing the call. Dremel said they would contact Amazon about the problem. If you have a problem, call Dremel customer service.

Just didn't go as good as I expected blade not sharp for long 3 cuts and started to get dull???

当方充電式のLITEに装着して柔らかめの木材の切断で使用を試みましたがトルクが足りず使用を断念。コツを掴めばギリいけるかもしれないが推奨は出来ない。 別で所有してる4000で使用したところトルク不足は無く非常にに良い切れ味で切断可能。ただ6mmの切り込み深さでは正直用途が限られる。 プラ板とかサンディングボードのような薄物で使いたい方向け。 木材で使いたいなら素直に丸鋸買う方が良い。 また取付も慣れないと割と面倒。ハンドリューターの取り付けの手軽さが失われてます。 特に説明書通りに毎回解体して収めるやり方してたら絶対使わなくなる。

Needed a tool to cut vinyl siding accurately, this did the job amazingly well. Great tool over all to do small accurate cuts.

Buen producto y buena relación costo beneficio. La sierra es bastante delgada, menos de 1mm por lo que no pierdes mucho material al cortar, por lo mismo se siente un poco frágil. Sirve perfectamente para MDF de 3mm.
