Works very well for grout removal [Posted on 2008-03-26]
I purchased this Rotozip to remove grout from our kitchen floor tile. As instructed on Rotozip's website I used the diamond wheel versus the grout removal bit and attachment. After a little practice I was flying through this project.
The right angle attachment got slightly hot after apx 30-40 minutes of steady use, not surprising or alarming considering the steady use. Just took it as a good reason to take a break and let it cool down.
This is the only thing I have used it for so far but would highly recommend this tool for that purpose.
Very versatile tool! [Posted on 2008-04-07]
I needed to remove a linoleum floor along with it's underlayment so I could install a hardwood floor in a kitchen. Cutting the underlayment under the toe-kick areas of the cabinets looked like it was going to be a problem. I considered the Crain Tools Toe-Kick Saw but the design was such that I worried about possible kick back tearing up the cabinets and, possibly, my flesh. This tool with the ZipMate Right Angle Attachment, XSHIELD Flush Guard Attachment and XW-WD1 looked like it would handle the task so I ordered this set.
The setup worked pretty well. I had to modify the XSHIELD to make the contraption fit under the toe-kick (see photo). This no doubt voids the warranty but it worked. If the saw blade was smaller in diameter and the XHIELD proportionately smaller, this would not have been necessary. Cutting went very quickly to within a couple of inches of inside corners. The corners still had to be chiseled. The XSHIELD rotates so that you can cut into either left or right corners. It is preferable to cut against the rotation of the blade like would be done with a circular saw. The XW-WD1 does not dig in like a toothed blade so you can cut with the rotation of the blade without having the tool pulled out of your hands. Cutting wasn't perfectly flush but was close enough (about 0.040"). Hit a couple of hidden nails but the XW-WD1 went through them without itself being destroyed.
I've cut out some rough window openings using the RZ20 and the XB-MPGP2 Tracing Bit. The technique is the same as cutting drywall for outlet boxes. Just let the bit ride on the framing while the cutter runs through the OSB. The resulting openings were much smoother than using a saw. Makes the window installers and finish carpenters happy.
I also own a DeWalt DW660 that was my basis of comparison for this tool. So far, I like the RotoZip much better. RotoZip has a much better variety of accessories available making the tool more versatile. RotoZip's 5/32" bits are also a plus. DeWalt only has 1/8" and 1/4" bits available. The 1/8" bits break too easily in anything harder to cut than gypsum board. The 1/4" bits cut too big a kerf. The 5/32" size is a nice balance. The three-jaw chuck seemed like an advantage over the collet chuck until a couple of bits worked loose. I called RotoZip about the problem that I was having. They said that they had not had any other reports of this and would send a new chuck. It arrived in two days! The new chuck has held the bits without problem.
While out purchasing some additional cutters at the local Orange box store, I saw this same promotional set at about the same price. If you can't wait for delivery, check it out.
Great, $$$ [Posted on 2008-04-15]
Works well, well built, sturdy. If only it weren't so darned expensive.
Also, the RotoZip RZVAC1 Dust Extraction Adapter Kit works very well.
Great Spiral saw, a Dremel on steroids [Posted on 2008-08-03]
This tool is much better than a Dremel . It has more power and more versatility and if you buy the RotoZip FS2 Flex Shaft Attachment you get pen like precision. This tool becomes a Dremel on steroids.
The jig saw handle provides you with a jigsaw that glides over your work cutting angles with depth precision that are only possible with a spiral saw and providing you with the firm platform of a jigsaw. The Sanding and cutting disk head attachment are equally useful and well made.
Great product and worthy of 5 stars.
Good Overall Quality [Posted on 2008-08-07]
But if I had to complain about anything, the motor's definitely a bit anemic. I find it bogs down more, and more often, than I'd like - especially using a cutting wheel.
I'm probably just a little too impatient, or push a little harder than the tool's intended to be pushed, but no matter what I use it for, I find myself wishing it had more power.
On the other hand, it's well built, and it's like a dremel tool - there's no one reason you really need one, but there's a million times you're glad you have one.
If you're just starting out building your tool aresnal, I'd say hold off on this one for a while. It's not the magic "do it all" tool they advertise it as.
If however you've already got all the basics and you're looking to blow some money on "gadgets" you could do worse than buying one of these.
