Just posted this observation in another thread but thought I'd repeat for those not there. Put a 14" DeWalt blade in the chop saw and it sucked compared to my usual Flexovit blades of choice. Half the cut speed(1/2" rnd solid). Acted like it was glazed up right from the get go. Just an FYI for those with abrasive saws.

Reply:Which disk was it?  I've had good luck with the thin dewalt disks.  The thick ones do suck *** though.My name's not Jim....
Reply:Ive got one on my saw now, and it is pretty bad. Atleast it doesnt smoke and stink like the Norton ones do, but this one acts like its all gummed up, and you really have to push it down to get anywhere, and usually that ends up tripping the breaker. I dont plan on buying another anytime soon...[Account Abandoned 8/8/16 Please Do Not Attempt Contact Or Expect A Reply]. See you on YouTube! -ChuckE2009
Reply:YES THEY DO! had one come apart completely on a cutoff saw when I was up on scaffolding cutting pipe, Sait blade lasted all afternoon, Dewalt lasted 1 cut and fell apart
Reply:I've had pretty good luck with Forney wheels, they seem to cut well and are fairly cheap.HH 187Miller Bluestar1EAHP AlphaTig 200X
Reply:Being a hobbyist, I don't cut iron day in and day out. I've had good mileage/ performance from the HF blades made in, of all places, Russia.                                                  MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:Boost: I think it's on of the thicker ones. ( just based on my Flexovit being thinner) I've used thicker Walter blades and they cut better then the DeWalt, but not as good as the Flexo.I was surprised to notice the Flexovit was made in the USA. For no other reason than it just seems like one of those items that would no longer be made in North America, or even Mexico. On the other hand, I'll save the Dewalt for free hand cutting on the chop saw. The Flexovit, because it's thinner, wobbles about a 1/2" when free handing. Thicker blades don't so much. ( Safety police, put it back in you pants. To all the rest, don't try free handing at home. It's dangerous. Wear all the protective gear you have and no beer before hand. )200amp Air Liquide MIG, Hypertherm Plasma, Harris torches, Optrel helmet, Makita angle grinders, Pre-China Delta chop saw and belt sander, Miller leathers, shop made jigs etc, North- welders backpack.
Reply:Yes, those Dewalt blades suck.  big time.The best that I have used were "scorpion" blades from the drywall supplier.Buy American, or don't whine when you end up on the bread line.
Reply:I am quite glad to be done with 14" abrasive blades for all but the crudst field work imaginable. I picked up an 18" abrasive some time back, and use that along with my multicutter for most of my cuting. It is miles ahead of the old abrasive blades. I still carry a 14" abrasive saw on the truck for severance in an emergancy though.

Reply:Thanks for the post . i just bought a 14 inch Dewalt chop saw. what do think i should do re turn them or keep them and try to cut steel with it. Also i have time i'm not in to big of a hurry
Reply:Try Sait brand discs..  Sait .045 cutoff wheels for 4 1/2 grinders are badass..tackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
Reply:I've had pretty good luck with Bosch 3/32 in the chop saw, cuts good & last pretty long. Has anyone tried 14" Metabo cut off blades?Millermatic 211 Lincoln Idealarc 250-250, ~500lb water cooled tig

Reply:Save up and get one of these next time you'll never go back to abrasive chop saws.  http://weldingweb.com/vbb/showthread.php...ight=evolutionDewalt, Sait, HF all really throwing money out the window unless you need to make a few cuts and you wont need it again for a year.  With abrasives, you get what you pay for.  The more expensive ones end up being cheaper in the long run.

Reply:I've been using Nortons from the local industrial supply.  No problems in a couple of years.  And less expensive than the big box.  I'm ready to go to a 9" cold saw but with the wife not working and back in school I'd get into trouble if I dropped a grand on a new saw.    Been looking at the Hyd Mech, Jet and Bailiegh.  I hate abrasive chops now, but except for plasma and Sawsall it's what I got.  I've though about the small HF or Grizzly horizontal band saw but would rather have a cold saw.
Reply:Hmmm...I must be missing something here. I use my DeWalt saw with their 14" cutting disks every day and I never noticed any problem. Maybe I'll have to try some other brands and see if there's a difference for me.On another note, I was in the Fastenal store the other day and picked up a couple of their "house brand" flap disks because the price was right. The first one I put in the grinder has been going strong on a big project for quite some time. I'm really impressed. I get a lot of my materials from a local scrap yard and of course there is a fair amount of rust that needs to come off so I reach for the flap disk grinder quite often throughout the day. This is the longest lasting disk I've ever purchased. Can't remember the name of the Fastenal house brand though. I'm thinking about trying out their other abrasives.Weird about the DeWalt though. Now you really have me wondering.Eric
Reply:Originally Posted by bert the welderFor some, the initial capital might not be there to use for a dry cut saw, so an abrasive is a good start, and like you said, if it's a occasional hobbyist, abrasive is fine.There are also things that I can do with an abrasive that can't be done on a dry cut saw.
Reply:Originally Posted by Cryo GalFor sure, Im not saying they dont have their place.  Curious tho, what can an abrasive do that a dry saw cant?

Reply:Originally Posted by Cryo Galmaybe we are talking about different saws then because the evolution they were talking about on that other thread has a stainless blade available.
Reply:$5 SS blade?  no wonder it only lasts 15 cuts.  A good SS blade will cost you around $250 LOLLast edited by Cryo Gal; 08-22-2011 at 07:24 AM.Originally Posted by Cryo GalFor sure, Im not saying they dont have their place.  Curious tho, what can an abrasive do that a dry saw cant?
Reply:Originally Posted by morgaj1I agree, Eric.  Never had a problem with the Dewalt brand.
Reply:I had some older Dewalt blades that cut well.  The ones I bought a few weeks back are junk. Originally Posted by Cryo Gal$5 SS blade?  no wonder it only lasts 15 cuts.  A good SS blade will cost you around $250 LOL
Reply:Originally Posted by bert the welderCan't free hand on a dry blade. As well, from what I've be able to gather, abrasive is better/fast for smaller dia. solid round like I use a lot. 1/4 - 1/2" as well as 1/8th flat bar. I can cut and feed real fast with the abrasive. Dry cut blade's teeth would catch and break off.
Reply:Originally Posted by AndyAI had some older Dewalt blades that cut well.  The ones I bought a few weeks back are junk.That's $5 PER CUT, not the blade cost.  $5 blade = cheap, $5 cut = not so cheap.
Reply:Originally Posted by Cryo Galoh yes, $5/cut is expensive.  Cryotreated blades...cuts 2-3 times more

Reply:I was unaware that they cryotreated the blades. Do you have something to do with that?Ian TannerKawasaki KX450 and many other fine tools
Reply:Originally Posted by bert the welderI didn't say they don't cut. They do. But compared to the cheap Flexovit blades, they are WAY slower. By half at least. And when you are cutting lots of pieces at once for a production run, speed is good. I've swung down my chop saw so many times doing production work, I can speed through cuts as fast as I can feed the material with out hardly looking at it. I'd love a dry cut saw, but it's real low on the spend-money-on list and I'd consider a band saw as competition.
Reply:I also use flexovit blades in my abrasive saw. No, they don't seem to wear any faster than others. But they definitely cut much faster and much straighter.Ian TannerKawasaki KX450 and many other fine tools
Reply:Originally Posted by Cryo Galwell, yes but I meant on a chop saw
Reply:Originally Posted by Welding_SwedeThanks for the info. I'm going to try the Flexovit and see how it works for what I'm doing. Are the Flexovits faster but shorter life? Usually there's some sort of trade off in performance. I'm not doing any production runs, just general fab/repair so I'm not trying to cut really fast. You know how a saw usually has a sweet spot in the feed rate? That's where I run my DeWalt and it seems reasonable.I don't mind spending the money, I'm just too lazy to change the blade all that often.Eric
Reply:Originally Posted by bert the welderHa Ha, that's what I was talking about too.By free-handing I meant holding the piece up to the abrasive chop saw blade, in your hands, to cut.IE: cutting a hollow ball in half.
