The Taper Tap is an internal catch fishing tool designed to retrieve tubular members from the well bore. It is the most economical tool of its kind for freeing fish. The Taper Tap is manufactured from high alloy steel and special heat treated. The hardened cutting teeth (wickers) are carbo-nitrided and machined on a shallow taper to provide an excellent grip for light duty pick-up jobs. Plain watertight wickers are furnished as standard equipment. Fluted wickers are also available on request. Taper Taps are furnished either plain or threaded for skirts.
