a good blade is the most important part of an abrasive saw. i have a $49 one from big lots thats 5+ years old and still going strong.
but the way you cut the material is also just as important if you want a good fast cut. do your best to avoid large flat spots for the blade to have to cut threw, it dose not like long flat surfaces. if you have a 1"X2" piece of square tube put it in the saw with the 1" part up and the long cut to the side so the saw is cutting down threw the long side instead of sitting on top of it trying to melt threw it. use the clamp movement spots also to keep from starting a cut in the middle if you have to cit large flats, so the blade first contacts the corner, not the middle of the flat.
if it dose get loaded up and starts to melt threw, scraping the blade with a spare piece of steel helps like Jim-TX said. also back off let it cool and re-cut.
keep in mind it is a chop saw. you wont get the sweet clean cuts of a band saw out of it. but its still a very useful cutter. grab a flap disk, or bench grinder to do a little clean up after the cut. most of the time i use a flap disk on my 4.5 angle grinder for clean up but if i am cutting several Pisces before welding i'll just stack them up and use the bench grinder for clean up.
in short:
a good blade (i use dewalt)
a good positioning choice
keep it cool and scrape as needed
expect a little clean up
if you keep those things in mind you and your chop saw should be happy for a long time. if thats not acceptable......


the MM135 is a great lil MIG. i love mine, its done way more than i ever expected out of it.
