    Edit, tap it first! Then clean up the threads after you saw it.
    That's what I was thinking - I have a .125 slit saw too. I think it's 4" diam. I'll go as deeply into the threaded hole as the arbor will allow then feed to hole depth.

    Good to know - tap, cut, tap.

    Also, lots of coolant on the saw and avoid climb cutting.

    Slitting saws tend to chatter like a mofo. I bought a cheap 4-1/2" diameter mini version of those big 14" dry cut blades from Amazon to use as a slitting saw when I was in a pinch for time.

    I was machining a set of solid 4-link bars from 2.125" dia 7075-T6 Aluminum and I was putting in some relief slots in the end (all the way to the arbor) after ID threading the bars to 1-1/4"-12. Turns out the blade worked awesome!

    I ended up running it at 30 IPM @ 750 RPM and the blade cut the 7075 like nothing. Blade is triple-chip design and the kerf width ended up at .064". Ended up making a total of 48 cuts and blade still looked brand new.

    At first I thought you said 14".

    You haven't lived until you jam a slitting saw!

    You know that gut wrenching feeling when you hear a tap snap? That's nothing compared to slitting saw drama!

    I've got 25 years of machining under my belt. No doubt about it, slitting saws suck.

    Triple chip grind is what allows the dry cut saws to mow through solid stock with no chip jamming because each tooth does not take the full width of the kerf per chip.

    I routinely cut 3" round aluminum solid stock on a 14" dry cut saw and each cut takes about 15 seconds taking it easy. Need to spray WD-40 on the blade before each cut to help lube it, otherwise NO issues.

    The slit saw works well - I just don't like using them.

    The first half of the other arm is in process as I sit here stuck on hold on my phone.

    Pix to follow later. I should have two finished arms by the end of the day.

    Do yourself a favor and pick up some boelube if you do a fair amount of aluminum work.

    The stuff forms a molecular barrier that keeps aluminum from sticking to the tool, even with extremely small quantities.

    I'll look into it, thanks.

    The arms are done!

    My mis-alignment when flipping the plates over ended up being about .002" - you can see the "seam" on the long face. I'm good with it.



    The uniball adapters will fit over this nub









    The pinch clamps work well.

    I still need to do a little clean up work on them - bevel a few edges, sand the top and bottom surfaces smooth - satin faces with machined inners will look pretty sweet when they're anodized. No clue on color yet, but they'll get it.

    5/8" end mill doing the outer profile. There are chips EVERYWHERE.
