    Yah,wait til you discover the deburring tools for sheetmetal,saves all sorts of money on badaids.
    LOL! OK...OK..I'm getting the hang of it now. Was putting way too much pressure on it and it was digging in. Can you use the sheet metal blades in any handle?
    They have some special blades for this rig for aluminum. I may have to get a few if these don't work for alu.

    They are wonderful tools.
    As Doc said, they work better if you tilt the handle and "Draw" the blade behind..not much tilt though. also the secret for doing holes is to develope a wrist action..do not be TIGHT..like white guys dancing..flow with the stock and let your wrist float around the edge.*
    The balls are for interupted and/or curved moves, and "no Balls' are usually for straight sections only.
    I like the balls mostly except for straight Aluminum pieces.
    Keep the spares in the handle, and if you have a chance, cut out a piece of paper describing each bit'ds function, and keep that in the handle too.
    when you don't like the results, read the instructions and soon you too can get professional results..but I can't help you with dancing.

    * for a 2 inch hole, my wrist probably makes a 5 inch circle with the bit trailing.

    Try inserting a small spring inside tool shank under cutting blade, this keeps enough pressure on tip to prevent its swiveling around. Dont forget to hold blade wwhen releasing or you will be looking for it.

    I have one of the deburing tools and use it with no problem. Great for deburing a bore while the part is still on the lathe just spin the chuck by hand I would not us it on the lathe under power that is what a file is for. Also use it for square blocks. When I worked in the precision shop we used a tiangular scraper for deburing . I has better control . Looks like a triangular file with no teeth. Broken end mills are great to for smaller holes . Use the style that the shank is bigger than the cutting diameter. And yes files are good to. In school that was what we used.
    A buddy actualy gave one to me several years ago.He ordered one from one of the mail order supply houses. He paid for one they shipped a box of a dozen what a deal!!
    They make deburring sets for a reason the need changes with the job and material. Also somewhat a matter of preference

    Okay, two tips: 99.9% of the blades are meant for right-handers, and operate on the pull.
    Another trick is that you can use a deburring blade to put a small countersink on a hole -- but you have to rotate the work and keep pulling the blade towards you. If you try to rotate the blade around the hole, it gets jagged on the opposite side, when you're pulling away from you.

    ...and yeah, you can get a nasty cut from them -- I was in a hurry, pulled the blade too fast, and caught the hooked blade on the web of my left thumb (holding the work) -- don't do that

    Who say's you can't teach an old dog new tricks. Deburring tools are simple, fast and if you're not careful capable of slicing your hands up. The blades for steel and brass both work well for their intended purposes but most of the other ideas (the keyway tool and others) are somebody's idea of a joke.

    Hold the part with the edge to be deburred perpendicular to you- as in, pointing towards/away from you. Put the swivel blade on the edge, as 'level' across the edge as possible. Then, just draw the handle towards you in one smooth, quick motion. The blade should trail behind the handle a bit.

    I've found that, on aluminum, just a tiny bit of oil on the blade helps.

    Use the same motion and in the same direction, on any surface. Go clockwise in holes. It works great, saves time and typically gives a more consistent finish than a file.

    I've had mine for literally eighteen years (since '88 when I worked at a foundry) and I've been using it put-near daily for at least four or five years. Since I use it mostly on aluminum, the blades last forever. I finally switched the original about a year ago when I was doing some stainless parts.

    Doc.

    Don't know....these blades all have a ball on the end.

    What ball? I haven't seen a ball on my Shaviv, though I don't have the Mango. In any case, I've got a B10 and B20 that came with it and I like it very well. I just ordered a set of 10 of the steel blades (B10 IIRC?) since they are HSS and I can certainly tell the steel blade has grown dull.

    Good on ya....nice to pick up a new trick now and then.

    John...I "think"...from watching the gurl....you have to let the tool do the work the way it was designed. Seems to me that she wasn't holding it as straight as I was....she had a lot more angle to the block and let the ball be the guide to the depth of cut. Just guessing here.
    I'll have to get further lessons next time she comes to work.
