    curcular saws

    can you use a regular curcular saw (with out screwing it up) to cut sheet metal or do you have to get a metal cutting saw?????

    i have been useing my cordless to cut metal roof sheets for the new shop that were buliding at work and it seems to be cutting ok but i just dont know if it will really screw it up over time.

    I love the machine. I never had a bit of trouble and they are so easy for anybody to use. When you want it calmed down to weld thin material, it will respond and the next minute if you want to weld 1 inch material, it will jump to the challenge, it will dig in, sometimes too much if you set your amps a little high. Once you find your sweet spots, your golden. I believe I had it down to 20 amps one time with a 6013 to stick a few razor blades together It is so easy to adjust as you are welding. I cant imagine using anything else. I highly recommend it. About the only thing I had to do to mine was put a longer power cord on it, the one it came with didnt allow me to move it more than a foot or two away from the receptacle.

    Metal cutting circular saw blades.

    Hello all,
    I've been following this forum for a little while.

    I saw this thread and thought I should add my 2 cents worth so I signed up.

    I am a carpenter by trade but have always loved metalwork.

    I've wanted a cold saw for a while but didn't want to shell out the big$ for a brand name saw for my hobby shop. I found a saw called "Evolution". I ordered a 14" chopsaw + extra blade and 2 7 1/4 circular saw blades from homedepot online. The chopsaw runs at 1500rpm and the circ blades run up to 5800rpm.
    Everything was delivered to my house for about $500! Really quick!
    The circ blades kick butt, cutting 1/4" and 3/8" plate like butter. You just have to control the feed speed or else you get some vibration and the blade cuts very fast and begins to chip the teeth a little.

    The chop saw is good also. Positive clamping , tool free adjustment. There is a little play in the main pivot but it gives a good square cut still .

    I know you get what you pay for so I was little wary, But I'm super happy with it , and $100 for a 14" metalblade and $45 for a 7 1'4 seems pretty decent value compared to the major brand names.

    Just my 2cents.

    i work on a farm and we go threw ALOT of sawzall blades and i always use milwaukee. but i picked up some 14 teeth per inch blades that were soupesed to be good for 3/16-1/4 steel and i was cutting 1/8 angle and it chewed them right up.

    well im not to to picky on sawzall blades I like milwaukee torch blades which are good for the heavier metal, and bosch makes decent blades too.

    here is a tip i learned that if u have to cut tile board or plastic U can use the fine tooth metal blade 18 tpi i think to cut it, thats if u dont have a all purpose blade handy. it works just like a hacksaw blade little slow going but a nice clean cut doesnt splinter the plastic at all.

    There are metal cutting blades on the market made for the high rpm wood circle saws, metaldevil comes to mind.
    FYI, the metal cutting saws are ~1/2 the rpm of a wood saw w/more HP.
    Good luck

    well i used wd 40 for lubrication i know sill me flammable liquid for lube on hot metal but it did work just smoked alot and smelled bad to boot. I was cutting 1/4 inch thick oil tank about a 500 gallon job, i was able to cut the tank in half and then the blade was shot to crap. then i used a 7 1/2 inch angle grinder on its side to cut a big square out of the tank . But that was before i had a sawzall, now cutting the tank is a breeze with a good blade and my milwaukee. although i wish i had a plasma or a oxy/cet cutting torch unit id be done allready. but u use what you got.

    I am with you, thicker stuff, sawzall, or plasma cutter.
    now i never said i was using the correct blade for the job lol but it is all i had so thats what i had to use.
