Does any one have any relative value opinions on diamond ring
saws or band saws.
They both do a fine job of cutting rock, slabs work best, but
can be cut if the material can be held so that it doesn’t twist
while cutting. Inadvertent twisting of the work will break the
Which is best depends on the application. The band saw cuts in
one direction; the ring saw can cut in any direction. The reason
for the difference is the way the blades are made. The flat
stainless steel band saw blade has diamond applied to the both
sides of the front portion of the
blade. The ring saw blade on the other hand, is a ring of wire
that has diamond applied to it’s entire surface. The band saw
blade is aprox .025" (.001 mm) thick & can cut a minimum 3/16"
(4.76 mm) radius. The ring saw blade is available in 2 grits, 80
& 140. The 80 grit is .039" (1 mm) in diameter, the 140 grit
blade is .031" (0.8 mm) in diameter.
There’s also a ‘jigsaw’ type saw available that uses a diamond
that cuts in any direction. The jigsaw has the advantage of
being able to accept standard jewelers saw blades & cutting metal
as well as rock.
All three saws use water as the coolant/lubricant when using
diamond blades. The jigsaw is adapted to use an oil based
coolant/lubricant for cutting metal.
The throat on all 3 machines is about the same depth. The saw
kerf on the band saw & jigsaw is narrower than the ring saw. The
ring saw & jigsaw can cut in any direction. The jigsaw can be
used to cut metal as well. The band
saw & ring saw cut faster than the jigsaw. They all occupy about
the same amount of bench space.
Band saws are available for about $400.00 Replacement blades
about $95.00. Ring saws are available for about $495.00.
Replacement blades about $80.00. Jig saw are available for about
$450.00. Replacement blades about $20.00.
