    An important technical aspect not stated

    The product is not correctly described. It not only matters the width of the shank to use it with, but it is important to state the diameter of the extender itself. When Forstner Bit is inserted into the Extender, the Hex Screws protrude slightly, adding to overall diameter of this tool. It should be clearly stated that this Forstner Bit Extender is only good for 3/4" or larger Forstner Bits, not recommended for use with 5/8" or smaller Forstner Bits. Great product, just lacks correct technical data.
