Superb tool -provided you know how to use it!

I believe the Rotozip is a superb tool and an absolute necessity for any professional or devout amateur. I recommend the premium model because it offers the most power, and the LED lights (”headlights” as I call them) are a nice accessory that makes using the tool in less optimal conditions more effective, such as cutting holes in ceiling sheetrock for recessed lighting. For tile work, the diamond blade is excellent provided you don’t exert too much pressure and cause the blade to overheat; having said that, it does an amazing job of cutting eccentric or irregular tile pieces that cannot be obtained by using a wet saw. Ditto for using it to cut metal pipe, masonry, plaster, or drywall. You should be very carefull to use the right cutter for the targeted material; for example, plaster will literally roast a saber cut bit; the company sells a special carbide cutter bit especially designed for plaster that costs around $8-$10; it is a must have if you will do this type of work. Overall, most of the replacement items and accessories are reasonably priced and of high quality. Be cautious with the speed adjustment, as some cutters such as the diamond blade are rated for a top RPM and going too fast will burn them out and possibly be dangerous.

The disk attachment is well made and allows rapid change of the cutters I have described. I was able to retro-fit this accessory onto an older model Zip Mate and have been very happy with its quality. Provided you know the limitations of this tool, it can be one of the most usefull around. Word of advice: keep a set of safety goggles, a dust mask, and perhaps ear plugs in the tool bag at all times. The cutters-especially those supplied for drywall and wood-cut at 25,000 rpm or so, and a lot of dust is thrown off and they can be loud as hell depending on the material you are cutting. Therefore, it is very easy to be distracted if dust is flying into your nose and eyes while trying to do use this tool, especially for extended periods of time. The more you can isolate yourself from the noise and debris that are normal byproducts of use, the better the results. Overall, anyone with half a brain will find zillions of uses for this tool and it will save loads of time for almost any project it is used for.

Quite a usefull tool
Bosch does make all the attachments for this series as for the last. In fact the RZ20-2100 kit comes with the cutoff/grinder attachment and circle cutter. They have actually increased the number/type of bits available as well.There is not much else to say other than the tool itself is pretty handy and does exactly what they claim it does. No less, but no more either. It is well made and pretty solid feeling. Feels like it would survive a good working life and a few decent drops, though I’m not willing to toss mine around to assure you of that. ;o)My first job with it was cutting out a section of the back vertical part under the top storage section of my computer desk so the monitor could be pushed back another 3-4 inches. Other choices would have been the jig saw, 3″ circular saw, or a hand saw. All would have been awkward without taking the top hutch off first. This cut right through the 1″ thick laminated pressboard fairly easily and I didn’t even need a guide to cut a darn near straight line. Its certainly not a required tool, or one of the first ones to go in a starting out tool collection, but if you have gotten to the point of buying any specialty or ‘convenience’ tools, then its a good choice. For $140 or so for the RZ20-2100 kit that includes the top line RZ20 unit, the cutter/grinder, circle cutter, a bit case, and a nice soft sided carrying case for it all, I think it is well worth it.

Powerful and robust, didn’t break quickly like my Dremel did
I bought my Rotozip kit after using a Dremel for about a week (at which time it broke and I discovered too late that I was among many this has happened to).
So I needed a more robust tool, one that could stand up to serious home improvement projects. That having been said, I find the Rotozip to be quite powerful, and much more robust than the Dremel (which will burn out on you in less than a few hours if you apply too much torque to it, in my opinion). The Rotozip runs at 30,000 RPMs as did the Dremel but is quite frankly a more sturdy tool. With the keyless chuck I’ve been able to put non-Rotozip bits on it (although being told at Lowe’s I wouldn’t be able to) and this seems to work. The Rotozip isn’t as nimble and lite as a smaller tool is, and can be difficult to use in tight spaces. But that is the tradeoff - Rotozip is bigger and powerful than other tools in its class.
Disclaimer - I didn’t mean to badmouth Dremel too bad - its a good hobby tool but can’t do serious work in my opinion. Also I tried the Black and Decker equivalent and managed to have it burst into flames within a couple hours of buying it (I was sawing through some wood with a circular cutting disc attachment when the motor blew up). But I’m not bitter
