    5.0 out of 5 stars Great Attachment!

    Great attachment. If you need to cut small or thin pieces of wood or plastic you really need this Dremel accessory in your tool inventory.I have only tried it on about 6-7 cuts thus far. I found the best results when the work piece is clamped and in using two hands, one to hold the tool and the other hand to guide the Mini Saw works the best. Perhaps with practice this method will change. Just as with any other power saw, let the tool do the cutting, not the muscles in your arm.Well designed and manufactured Mini Circular Saw. Another Dremel tool that’s well worth the price. Very easy to attach to and position on the hand tool.The saw cuts quickly through the material and leaves a smooth edge. The tool is light duty which should be evident from looking at the pictorial in the ads. Use the right tool for the right job!I have not had any trouble with the blade guard or seeing the guide line and kerf through the clear plastic housing. It cuts a clean thin kerf. Keep in mind it is not a heavy duty cutting tool.“Spinning” in collet chuck problem resolved.Reading the reviews before purchasing this tool a number of them said they encountered problems with the attachment “spinning” in the Collet Chuck. In spite of those reviews it looked like such a great tool idea that I just had to try it for myself.Indeed there was a rotating problem. When I attached it to the Dremel series 4000 tool the Mini-Saw would rotate freely even though the coupling knob was tightened as far as it would go. I then tried it on a second 4000 and had the same problem.While on the phone with Dremel Support, they tried the 670 Mini Saw on a 4000 tool. The saw tightened securely on their tool. They then thought I may have a defective unit and sent out a replacement. The exact same problem occurred with the replacement unit.I called Dremel again and they had no answer for the problem. All they said was send the 2nd unit back to them. I said “before I return it I would try to find a nearby Dremel dealer and take my 4000 with the 670 attachment to them to help resolve the issue.”I then took a closer look at the 670 assembled on the 4000. It became quite clear that the problem was due the coupling knob bottoming out on the front end of the 4000 housing body. I decided to remove a small amount of material from the open end of the black coupling nut. I ended up removing .050/.060 of material, cleaned up the burrs and reattached it on the tool and it tightened up securely. No rotation at all. Did the same to the replacement unit and it also worked. Now I have two Mini Saws that work perfectly.JohnOakHill Wood Creations

    I had to cut out some paneling in a bathroom with several tight corners that would not accommodate any full sized cutting tool so I decided to try this out. At the price I didn't really expect much but didn't have any better ideas. The attachment fits easily once you realize that you are not too smart to need to glance at the instructions. I started tentatively at the lower speed and it consistently made ragged cuts and/or stalled. After I switched to high speed it began to slice easily through the 3/16" paneling. So far so good. I then began to take up old flooring and discovered that the glue down plastic tiles were covering two layers of linoleum and an additional square glued down tile application. Since I wanted to take out square sections and had no good way to cut the linoleum I decided to try this tool. Worked like a charm. I was taking out manageable sized sections within minutes. It easily cut down to the base concrete and the blade did not deform even though it sometimes hit the base concrete hard enough to spark. If fact, it still cuts wood smoothly. I haven't tried solid hardwood but suspect that would not go as well. I will probably try that out eventually.

    Cons:- Difficult to see exactly where the cut will be made (particularly after cutting any wood), which could be a problem for exact cuts. Not only is this due to the curvature of the plastic shield but also to any sawdust kicked up being sprayed across the shield and blocking vision. A printed dark line around the outside of the shield (which would remain visible during use) could help solve some of the precision cut issue.- Installation [and subsequent] is dangerous for the Dremel (and potentially for user). A small piece from the original Dremel configuration (not clearly specified to be removed from the installation instructions) was left inside the tip (a Y-shaped piece which appears to be used to grasp other inserts and is hidden inside the Dremel tip). This caused seating the saw attachment to the instruction recommendations for tightness to be insufficient; and the attachment spun around and flew off. Not only is this a potential cause for injury, but it also ruined the threading on the Dremel.- Cleaning the inside of the shield requires dismantling (removing the blade. This could potentially be improved if it were hinged to open up for cleaning.Pros:- Came with the appropriate blade (couldn't tell from the advertisement whether the blade was included for sure)- Cut cleanly and reasonably deeply

    Great option for thin materials needing squared-cut edges. I like the safety guard, too, but it's no replacement for being smart (and a little paranoid--is a spinning blade, yo!).DEFINITELY perform the run-in instructions! It makes a big racket until it's run at speed for a few minutes.

    not as good that I expected

    私が悪いのでしょう。

    説明書通りセッティングしましたが、安定感が無く、怖かったです。きっと、馴れていないのと、私のなにかが悪いのでしょう。初心者向けでは無いですね。

    Gran precio y efectivo en uso
