Rotozip Burn Out [Posted on 2003-04-02]
I just wanted to confirm what a few others have said here. The Zip works great with one problem, the fan. If you buy one of these and actually use it more than the average Joe be ready to fix the fan. I have had two and exactly as stated in prior reviews, the unit gets hot and the glue holding the fan in place loosens allowing the fan to slip down the shaft and into the housing. The first time this happened I just had it replaced. The second time I had read these reviews and decided to open it up. I found exactly what other reviewers have stated. I too am using bearing retaining compound to glue the fan back in place. You can get it from Loctite. I recommend using the kind for high heat.
Revolution design flaw [Posted on 2003-06-04]
I have been using the Revolution spiral cut tool for a few months in a professional capacity, previously using the Dremel for drywall cuts. The Revolution shaft lock has be redesigned which is good news, the old design would fall apart with minimal useage. I am on my third Revolution now within 5 months. Its a great for cutting drywall, however if you use the tool for harder materials such as plywood, hardyboard, OSB, or particle board expect a drastically shortened tool life. I use this tool because it will not crack or split Formica. Heat generated while cutting, travels up the shaft and begins to melt the plastic fan blade. With the fan's tight tolerance to the housing, it begins to drag causing more noise and quicker failure from wobble at 30,000 rpm. A few countertop sink cutouts is all this tool can handle in 3/4" particle board before failure, with changing the bit 3 or 4 times for each sink to insure a sharp bit. Maybe if you could allow the tool to cool for 30 minutes for every 5 minutes of cutting, it would last longer, however this in impractical with a customer standing over you. And there is only a one year warranty from original purchase. Since they replace the tool and not repair it, the warranty should begin a new period. This would force them into incorporating a billet aluminum fan blade more quickly. Its hell to be at customers and have a tool failure. Maybe I should become a dealer and carry a few Revolutions in stock on my truck and perhaps even bill the customer for a new tool each time i use it, under consumables. ALWAYS WEAR EAR PLUGS AND SAFETY GLASSES WHILE USING THIS TOOL.
For the HOME user, it is a MUST have [Posted on 2003-10-08]
Myself, I'm a lowly home owner. I bought this tool, because of it's maneuverability and speed with which it cuts. For roughing in flooring in my attic, it performed better than any tool I have ever owned. The power, cable and phonewires in my attic were easily managed by cutting a quarter inch deep trench in the 2x4's, such that the plywood wouldn't crush them. I then was able to freehand cut the plywood around the roofing supports. All said and done, I had my attic completely floored in about 3 hours. It would have taken several weekends of my time using conventional jigsaws, or hauling stuff up and down the ladder. I cannot dispute the issues of the fan blade; I do not doubt that this happens with commercial use. However, for the home user it has not been a problem for me. I gave it 4 stars, instead of 5 stars for the simple reason that I agree with the commercial users. The fan should be able to withstand the temperatures the tool will generate in continuous use.
Great home handyman tool [Posted on 2003-12-17]
One of those tools you thought you might not need but are now darn glad you have. You'll wonder if this tool will help with pretty much every challenging cutting angle or clearance issue. Used the accessories almost from day 1, so the combo makes sense. No regrets.
Another cooling fan failure for an otherwise great tool. [Posted on 2005-09-02]
I'm the typical doityourselfer and I certainly think I do not use the Rotozip for more than it was intended, but recently it started sounding like something was loose and scraping inside of it while in use (a very unpleasant and alarming sound). Like other reviewers, I opened up my Rotozip to discover the cooling fan rubbing up against the housing. Years ago, I paid over $200 for my Rotozip and am pretty angry that such a potentially dangerous flaw would find its way into such a widely sold product. Aside from attempting the Loctite fix, I'll probably replace this tool with a Craftsman brand rotorary cutting tool simply because it would seem that brand would make a difference in this case - especially if you plan to use a product for more than a few years. I will never endorse Rotozip tools should anyone ever ask me.
