annabel,

    A cut off wheel is a tool used in your flex shaft machine to cut
    metal. This is not my first choice for removing sprues but it is an
    option if needed. 

    When casting metal we need to use more metal than what the actual
    piece requires for sprues and a button. A button is the part of the
    casting that feeds the sprue and casting and looks like a cone shape
    or button shape piece of metal. 

    Do not use the same files for wax and metal. 

    As far as what the casting house will do after casting depends on
    the casting house and what services you have asked for. Some
    automatically complete the whole process and others just cast and
    return the raw casting. 

    I do casting work for the trade so if you need a backup source
    please contact me off list at greg AT demarkjewelry.com 

Good luck
