    Universal Insert Lathe Tool bit Holder....Get any angle on that tool bit.

    I saw this on line while watching a video and it looked so good I had to make one.
    The demo that I was watching was using an Aloris cartridge insert tool bit.
    This unit could be set to various angles in multiples of 15 degrees.

    I wanted mine to be any angle! So I left out the cogs and just made a smooth cartridge.
    I am using TCMT carbide bits but HSS bits are available and I am waiting for mine to arrive.
    I cut a steel rod in the lathe. Faced it, turned a shoulder, made a chamfer, and turned a cylinder without
    changing the tool bit. On my mini lathe I made cuts of .020 infeed or .040 material removal per pass and
    the operation went smooth without the insert moving and without chatter. What more do I need?

    TCMT insert use an M2.5x.45 tapered screw..(get mine from LMS)
    The cartridge is retained with an 8-32 allen cap screw.

    So here a couple of pics and my simple drawing of this versatile tool bit.

    Make one, you will love it.

    Cheers, JR

    Thanks olderdan and clavius. I have a project coming up that will use all of this tools versatility.
    It is not a tool but I will post a link to the project here after I build it!
    Hint: Outerspace kids will want one!

    Cheers, JR

    Thanks Jon. The tool is turning out to be very useful. I have used it along with a cutoff tool and threading tool
    on my latest project and the three tools mentioned are the only ones I have needed. The tool post stays square and
    it makes the quick change tool post "Quick". Much quicker than when I used bits and kept changing the tool post angle.

    Thanks for the gift cert. It will be converted to Inserts!

    Cheers, JR

    I think I just saw the same video, googled the tool and saw the price. This seems like a very useful tool and surprised there is no cheaper copies

    Indeed. For about $300.00 you can buy the commercial one. It is bigger but my lathe is smaller.
    Mine cost about $2.00 and maybe half a day to make..
    Fast becoming my "go to" lathe tool bit.

    Cheers, jr
