    I understand these are pretty much the dogs danglies for boring and facing.

    But can anyone tell me if the arbor can be changed on this model?

    I want to make a mini line boring tool out of a mag drill.

    Some are some aren’t.
    Show me a picture of the code
    I wouldn’t use a fine piece of tooling like that for a line borer though

    I was wondering this too, having been watching a few on ebay a while back. Most seemed to be int or morse taper shanked, and i needed r8.

    id have to be feeling brave to run a big head like that on a MT shank, theres a off centre load that will try to wobble itself out.

    Agreed, they're too nice to bugger fixing knackered diggers. :ashamed:

    Absolutely, you would want a drawbar or draw stud or something to pull it into the spindle.

    You use a wedge to hold in the spindle. The mt ones are for horizontal borers and the like

    interesting... i've seen the double slots in big MT shanks and assumed one was for a locking wedge, could you explain how a wedge work in a single slotted MT?

    Is that what he slot in the taper is for? I was trying to figure out how a drift would fit to eject the tool. :dontknow:

    I've just looked at the photo of my own one and answered my own question, the slot is the locking slot for the double slotted spindle..... doh
