I mentioned the rotozip saw I got for Christmas and the furnance install
where I found it so handy. Here is rotozip's url:
http://www.rotozip.com/
Since it was a gift, I'm not certain of the price, but I think it was
around $60. It seems very robust, though not much heavier than a
flashlight. It consumes 4 amps and runs at 30,000 RPM. I think it is
impossible to stall it, or even slow it down while using it. It
exhausts away from you so you don't get a face full of dust.
It does generate some fine dust, though, and it "sings" quite a tune at
30K RPM.
According to the write up, they have been making them since 1972 for
contractors, but only recently started marketing them for general sales.
Following is a write up I cut from their web page:
The Company and
The Technology
In 1972, Roto Zip Tool
Corporation pioneered spiral
saw technology by inventing
the first drywall cutout tool
and marketing it to a very
receptive construction
industry. Inspired by an
experienced tradesman, the
original product was
designed to speed-up the
process of making cut-outs
for electrical boxes, windows
and doors when installing
sheets of drywall.
In recent years, the Spiral
Saw system has evolved to
become the tool of choice for
tradesman, do-it-yourselfers,
hobbyists and crafters. While
its primary advantages are
cutting speed and control,
the Spiral Saw slices
materials rather than the
ripping action of jig,
reciprocating, and circular
saws. Using a variety of
patented Zip® Bits, this
spiral cutting action cleanly
slices through virtually any
type of commonly used
building material (up to 1"
thick).
I have no financial interest in this company, and only found out about
it on 12/25/98.
I do like it very much, though.
