Accurate and fast setting of collars


        The Bohan drill collar setting unit can be used in
        conjunction with CNC drill or router machines using
        pre-set drills and cutters with location collars.


        Our setting unit can be supplied to suit individual
        customer requirements in respect to collar
        diameter and thickness. It has been designed for
        the fast and accurate setting of carbide drills and
        router, using a precision imperial dial gauge which
        virtually eliminates drill point damage.


        Setting collars can be removed from drill and
        router cutters on the unit, with collars
        automatically dropping beneath the base.
