Dremel DSM20: Unboxing and first impression

There's the thing!After announcing Dremel's device test campaign for the new DSM20 compact saw last week, two of the babies found their way to us yesterday. Before we do a detailed test, you will learn a little about the equipment and our first impression of Dremel's reinterpretation of the circular saw.

Dremel DSM20: Unboxing and first impression: dremel

DSM20 and included accessories. There are a cutting disc for wood / plastic and three metal cutting discs. Slices for tiles and stone must be purchased separately.

The package has already led to the conclusion that here again a suitcase in Dremel standard format is used. Who is Dremel regular and has a suitable shelving system for the case in the workshop, so can be reassured: With the DSM20 should change a lot - but only within the usual 40x10x27 centimeters!

A practical tab for tearing open the packaging is sought in vain, it is best to cut with a knife one of the cardboard tabs on the narrow sides of the package. - We are the Wurscht! Dremel would rather put money in the content than waste it on packaging design. - As expected, the classic gray Dremel suitcase comes with blue lettering and white type design to the fore: Stable case and confidence-inspiring closures, massive feel. Can you probably just drop it.

The locking of the rip fence is unnecessarily fumbling. A loose Allen screw is quickly lost.

The included rip fence allows guided longitudinal cuts, e.g. in wood panels. The distance from the leading edge is a maximum of about 26 centimeters, for larger distances, the supplied crossbar is too short. (True handyman know how to help in such cases, but certainly.) Unfortunately, the attachment of the rail is unnecessarily impractical. It has to be screwed tight with a small holding plate together with Allen key. Apart from the fact that screw and metal plate can be lost very quickly, that is out of date and really unnecessary!

The set included in the set "Beam guiding intent"Can be pushed over squared timbers to 37x86mm. This can also be used to cut beams that are thicker than the maximum depth of cut of 20 millimeters. Simply slide the guide attachment in the desired position, cut from one side, turn the workpiece and also make a cut from the back along the rail. Also a suction for a dust extraction is included.

The statement by Dremel "The product contains a large selection of grinding / cutting discs" (Dremel product page), is not quite true. It is a cutting disc "DSM500" for wood and plastics and three discs "DSM510" for metal included. The Masonry and Coarse Masonry Slabs (DSM520), Marble, Concrete, Brick, Porcelain and Tile (DSM540) and Offset Sanding Discs (DSM600) are self-procuring; and that's not quite cheap with 17 Euro per disc!

The cutting depth adjustment (max 20mm) makes a valuable impression and is handy in the operation. A relatively tight spring facilitates plunge cuts.

For safety, the device has a small lever as Einschaltsperre, which can be easily operated with the little finger. A locking knob facilitates longer work. With the DSM20 are straight normal cuts and due to the comfortable depth adjustment flush cuts on floors or walls possible. Especially this one flush cutting in combination with the handy shape should make the device interesting for many home and craftsmen. in addition to the already mentioned guided longitudinal sections are also miter cuts possible, but only with a separately available angle stop. (With 14 euros even cheaper than a single cutting disc!)

The good View of the cutting line should save additional time compared to normal circular saw / Flex. However, we must relativize this statement. The protective cap on the front has a small notch that can be attached to the tear, but the plastic frame is again so wide that marks on the edge of the workpiece disappear immediately below it as soon as you start sawing. Here an (almost) continuous recess or a transparent window with a guide would have been desirable, as it is known from other tools.

Cuts against the direction
One reads a lot about the advantages of "toothless" sawing with the DSM20. For example, plunge cuts without a backlash should be easily possible, just as sawing against the running direction of the saw blade. We will take a closer look at these functions shortly, but we will do it at our own risk with respect to the cuts in the opposite direction, as the user manual states in this regard:
To avoid kickback (a situation in which the disc tends to jump out of the workpiece), you should make cuts in the same direction that the disc rotates." And also: "Be sure to read and understand the notes in chapter 'Kickback and related warnings'. "- However, one looks for such a chapter in the manual in vain. (Who finds it, please let me know!)

Preliminary conclusion:
Apart from a few inconsistencies makes the DSM20 a decent first impression. Only the cost of replacement cutting wheels we find a little bit too high, also the loose locking screw for the rip fence is rather disappointing. We are curious how the compact saw beats in our tests!
