The Dormer Straight Flute Bottoming Lead Hand Tap is a UNC-threaded tool built to ISO standards, ideal for tapping medium-strength carbon and alloy steels. It features a bottoming lead, which, while more difficult to start, allows threading nearly to the bottom of a blind hole. Best used as a machine tap or, when used by hand, in sequence after a taper and plug lead tap or a starter and intermediate serial tap for optimal results.
