hi to all
i am looking for a portable saw for cutting steel that:
1-cut horizontal jobs.i need to cut matrials in the earth.like a door jamb
3-long life blade that can be sharpened and be usable for years
i find 5 saw.but each saw has a Defect.
and band saw
*-undercut is the best for me.but i cant finde any information that Imply
it can cut steel.i search for blade that can cut steel with undercut
saw,but found nothing
*-dual cutter is very good.but hard to find saw blade is a challenge for
me.i dont know can i use 2 circular saw blade for that or not.
*-circular saw is good especially Because Of its blade.but im not sure can
i cut a jamb like steel in the earth from butt?
*-angle grinder sparking is the main problem.is there any blade like
circular saw carbide tipped blade that fits in to it?
*-band saw blade life is short and cant be sharpened
im so Upset about it.i dont know what saw with what blade is right for
sorry for bad english:(
oh i shot a pic for example from my cutting position:
Very hard to impossible to control in the space you need to cut, and not
have it jump or kick. Can be used for tiles, but dusty. Once you get past
a certain rpm, you will have sparks on anything.
There is no graceful easy way to cut what you want to cut. It is very
difficult, and even when you do get it cut, you are going to need a grinder
to clean it up.
You basically can't get there from here.
Cutting torch is nice, but they have their drawbacks and hazards, too.
Heart surgery pending?
Read up and prepare.

i search for zipmate carbide blade and found nothing:(
what is different between cermet and carbide tipped blade?and which is
best(spark less and longer life for metal cutting?)
is there any chance to find carbide blade or fit circular saw blade on
if not is there a way to cut vertically with circular saw?
something like adjustable circular saw for vertical and horizontal
again thank you for attention..
The real problem is that the metal jamb is full of concrete. It
is an interesting combination that eats saw blades. You will do
best with a fiber blade that can be mounted in an undercut saw.
There will be some minimal sparking, but mostly dust. It is
possible to spray a light mist of water as you cut that eliminates
both the dust and the sparks. The blades are relatively cheap,
but they disappear fairly quickly - there is nothing to sharpen.
Weld cutting disks in an offset grinder work about as well, but
are harder to control and won't stick out enough to make a single
clean cut across the 2" of jamb. Carborundum grit blades for a
Sawzall are SLOW and expensive, but will get the job done.
Steel cutting Carbide will work, but won't last long because of
the concrete. A torch will not work. HSS blades will not work.
Diamond will be destroyed, but will work.
