    In Need of Dry Cut Saw Blade Recommendations 14"

    Hi Guys,

    About 4 months ago I purchased a new Trajan Q1400 dry cut metal saw and i've been using it a lot on 1/8" bar stock. However, this is the second time I've burned up a $100 blade in a 4 month period. I've been really careful not to press down too hard or travel too fast and I still burned it up (this time on 1"x1" 1/6" square tube). I contacted the manufacturer when I burned up the first blade and they did nothing but cover shipping and handling on the second one. At this point, I'm done with those blades. Does anyone have recommendations on good 14" metal cutting blades? I'm hoping just their blades are sh$% and there isn't an issue with the saw. I'm willing to pay for quality if there is value so let me hear what you got!

    I found a local place that will sharpen the blades for $20 each so I'm going to give them a shot. The guy at the counter said they sell MK Morse blades and a lot of people seem to like them. Unless I hear from you guys, this may be my next purchase after I wear out the current "Q Saw Quartz" blades.

    I have a few spares one is a evelution 66 tooth on the saw now that replaced a 36 tooth that came on the saw and one spare is a oshlum 80 tooth.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    To the OP, how many cuts have you made each time? Saying you used it for four months doesn't really mean anything.
    How tall is the 1/8" flat bar? If it is too tall, 4-6", it may wobble some during the cut.
    Are you supporting the material on the right side of the blade?
    When you cut the square tube, do you use a set of "V" block to hold the square tube in a diamond shape?

    As you mentioned, find a local place to sharpen the blade. It only cost $20 to sharpen a blade near me. Make sure you get it sharpened before you start to chip or lose teeth.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    This time when I burned out the blade I made about 100 cuts total in 2" wide 1/8" stock clamped vertically. Granted a few of the cuts I tack welded the 2" bars together (making it 1/4" thick) to reduce the number of cuts I had to make. I did not use a set of V blocks to hold the square tube in a diamond shape. Searching the forum I just found out yesterday that it was a recommended best practice. Maybe I have to make so V-block jigs or something for the future but would this really pre-maturely burn out the blade?

    100 cuts is pretty terrible in my opinion. Should be 100's of cuts.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    What type of saw? What is the RPM of the saw. Could be wrong type of saw for running metal blades. There is a difference between abrasive chop saw and metal chop saw.

    Edit: NVM I just googled your saw. Maybe it is the way you are orienting the material being cut.

    I don't understand what's going on... I'll see how long the blades last once re-sharpened. Maybe I'll post a recording of me cutting with the saw to see if I'm ignorantly making a mistake but you'd think it would be pretty straight forward.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    I'll reiterate what PSA says about wobble... and any kind of movement at all!!! flex is a killer when it comes to thin stuff<=1/8"

    And on the 1/16th tubing make sure you use a blade that is rated for 1/16th... most of the standard blades are good only down to 3/16... or 1/8th after that you need more teeth.

    As for garbage blades, the worst I have ever used were the steel demon diablo by Freud for my handsaw(5-3/8) on the other hand oshlun, milwaukee, dewalt, blades have performed great and are very forgiving to operator error and with careful use will last more than hundreds of cuts... I'm thinking thousands

    Did you chip a lot of teeth after cutting the 1/16" wall square tube? Like others said, that is very thin material for the typical tooth-count .

    Is there a chart of ideal tooth count vs thickness? I still have the 80T mine came with but I’d rather get more blades to match material than ruin an otherwise good blade.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    I'd have to look, as I haven't seen one myself. I'm someone here has more experience and can relate to a tooth-count-to-material-combined-thickness ratio kind of suggestion.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    Per the manufacturing website, the blade is rated for 1/16" thick to 3/8" thick steel. I just got the sharpened blades back today from my local tool shop and put them to use. It seems to be throwing less sparks than it did brand new. It's hard to tell at this point with just a few cuts, but depending on how long the blade lasts this time, my theory is they may be shipping dull blades. I'm curious to see jigs for cutting square tube in the diamond position. I definitely need to make that a standard practice moving forward small and big.

    I donít know if itís feasible to set up something like this in your saw vise but this is what I did for one of my bandsaws.

    Get a couple if pieces of 1inch by 1/8 angle. Weld to a piece of 3 inch by 1/8" flat bar.
    This example is to 4 inch flat bar and it is a bit too wide.

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    Pat are your V block jaws screwed to the OEM jaws?

    Is it finicky to set up for longer lengths? What about different sizes of square tube? Would it better to be able to have a height adjustable V block to accommodate them so the V of the square tube is supported by the bottom of the vise and feed tables? Have I asked too many questions yet?

    Re: In Need of Dry Cut Saw Blade Recommendations 14"

    I have another set that is narrower and is made with 3 inch flat bar. I also made a bigger set made with 2 inch angle.
    I use the smaller set for 1 to 3 inch square tube and the larger set for 4 to 6 inch square tube. I have even used these to cut some rectangular tube.
    You can also just use one V block to cut angle. I made a compound cut that way for a sculpture.
    I usually support both ends with a standard roller or just a block of wood.
    I have used these v blocks to make a compound miter on square tube also. When I do that, I am able to slide one block farther out so it is close to the blade and supports the work.
    The clamping action of the vise is very secure and I have never had it come loose.

    Wow that's pretty slick! I am curious how that works with different sizes. If you'd need it to be adjustable, you might be able to make the top angle iron slide-able. I might try to fab something like that up. Cool!
