The set includes two sliding jaw type tap wrenches and T-Bar type tap wrench together with two steel die holder with knurled screws. The taps and dies contained in this set are precision tools.
Supplied in heavy-duty blow moulded storage case. To cut an internal thread, select the tap of the desired size, tap wrench, proper drill size or hole size, and lubricating or cutting oil. The proper hole size is very important in the formation of good threads. An oversized hole results in reduced thread height, an undersized hole will overload the tap and cause undue breakage Refer to the required drill size permanently marked on the shand of each tap and drill the hole to desired depth. Secure tap by the square in the tap wrench and start threads by turning clockwise Great care must be taken to start the tap square to the hole.
As the tap is turned it bites into the metal and leads into the hole. After the tap has been started, metal chips that flow into the flute spaces must be broken to relieve pressure on the tap. O cut an external thread, such as on a bolt, select the correct die for the rod being threaded, die stock, and lubricating or cutting oil. Size of the rod or bolt, is of great importance.
It must be no larger than the desired thread, and preferably 005" to 010" undersized. Oversized work may damage the die and will make turning very difficult. Slightly undersized work is easier to thread and furnishes enough thread height for normal use. After securing the part being threaded, insert the die into the die stock and run the screw snugly into one of the recesses in the outside surface of the die.The recess and slot pattern of dies allows use with a variety of die stocks.
