Hi Mike
I call the RotoZip tool,"the bit breaker",works great in dywall but if you put in into a real load like try to cut 3/4" pine foreget it,unless you make 5 or more cuts at the same slot.
I used every bit I got with this junk tool and then I got some more,not smart on my part but you live and learn.
Then if you put in a 1/4" bit, kiss that bit good by because you just burn up a good bit.
I got feed up with it and put it on my Router Crafter with a speed control that works great for small jobs.

break them bits

Pros: handy
Cons: bits keep breaking and high speed
Thought this would be the tool of the century,being able to reach hard trim spots makes this tool handy but..........when it comes to heavy duty like t1-11 them eight inch blades fail.I always buy a pack and use them all,they keep breaking off.Thank god i didn't chuck my jig saw.Maybe quarter inch blades would improve this tool for wood cutting and a 30 20 10,000rpm speed variation would be a great improvement.No it's not me as i was at home depot and found that contractors were having the same problem.I don't consider this product when i do a job and rate poor although i haven;t used it on sheet-rock it could perform well.Until it's improved the roto-zip cord and one speed model sits.

Rotozip
For rough cuts in soft materials like drywall, the Bosch Rotozip tools use spiral blades that can cut in any direction. A jigsaw handle attachment, the RotoZip RZ-JSH (*est. $40), keeps the blade at 90 degrees to the surface being cut. The basic tools range from 5 to 5.5 amps, priced from the simplest RZ01-1100 (*est. $60) to the variable-speed RZ20-4000 Pro (*est. $145) with three other options in between.
Kits add a range of accessories at some savings in cost. For example, the RotoZip RZ20-4000 Pro Cutoff Kit (*est. $145) includes the jigsaw handle, a right-angle attachment and several other accessories. All carry a one-year warranty. You can find more information on the Web site (
