  • Need small boring bar.

    I have a Sandvik cormerant bar .315 in dia. about 5" long. It fits in a square split sleeve holder #131-408 which is .500 x 3" long. It has a carbide tip which I smashed doing a bore. Where can I find one of these? I tried MSC, Enco, Grainger, and E-Bay. It may be discontinued because it is probably 30 yrs. old. I have it since the 70's. It was a gift from a friend of mine. It was one sweet little tool for doing bores under .437 dia. Funny thing is I don't remember breaking it and why I didn't look for one then is a mystery. I need one now or I'll have to grind a circle C down to size to make the bore dia. I'm working on. I know Sandvik is still in business ,maybe they would put me on to a supplier. Thanks Boot

    All you need is an 8mm shank boring bar. There are ones which accept carbide inserts as well---those will be a longer OAL to accommodate your square adapter sleeve. Too many to list; the above are convenient.

      Look on ebay for these items, for example

        The Ebay item is/was inch size, the OP's tool was 8mm.

        The original boring bar may be fixable. It can also be replaced with a new on that's 8mm, right from Sandvik Coromant. They have plenty of distributors, so contact them to find one in your area.

        If the boring bar is fixable, send it off to T&A Tool of Adams MA, Tim will fix it like new for 1/2 of new cost.

          Why not wrap the 5/16 tool in a layer of foil and call it a day?
