a recent project, cutting up some grating, didn't want to use O/A torch, too
cheap to buy a dry cut saw, just bought a dry cut saw blade (milwaukee 10"
from amazon.com) put it on my table saw (rpm's were substantially lower than
my circular saw). worked, what for me was, OK. i use a sliding plywood
miter box on top of the tablesaw bed. one thing though, with grating,
towards the end of the cut the already cut pieces could/would pinch the
blade, which sucked, i broke/chipped a few (BRAND NEW) teeth that way. dry
cut blade was more expensive i'd imagine than an abrasive cut off saw blade,
less sparks though i'd imagine. don't know if you can cut sheet metal with
it though, i'd guess you'd have to feed it slowly but more importantly very
The cutting action is OK, as far as that goes. I just can't get a straight
cut out of it. And I don't know why I'm surprised it makes that
burnt-grinding smell. (The woodshop is in the basement; the metal shop is in
the garage, for that very reason.) Planning and daydreaming sometimes leaves
out the details of the other senses, I guess.
The price for the abrasive blade is right: $4 and some change. Run-out and
warp is what you'd expect for that: god awful. About .030 warp on the face,
and front to back is out .010 mil. (That is kinda weird. I dialled in the
trunnions and a Forrest blade to just about 1 mil not that long ago. It's
the blade, not the arbor.)
The size of the work doesn't lend itself to clamping to the plywood sled,
and I can't find a 1/2 bolt this moment to clamp things to the miter gauge.
I'm glad to call it quits. Should maybe think about getting a shear and
press brake for this kind of work. It's a simple job if you have the tools
The table saw will work fine, but you need a Tennyru style blade (C6
carbide). You can get a 7 1/4" Matshushita for $35 from Medford Tool:
It will fly through 16 ga & the cut will be clean and straight. Yeah,
kinda noisy and the chips are VERY hot. I have a small dedicated TS
with one of these blades, just for steel.
