Will result in smoother threads and longer tap life. Continue threading until the tap. Passes through the part or to the desired depth. When tapping a blind hole one that does. Not pass entirely through the part take care in drilling to provide clearance at the.
Bottom for chips and the starter threads. These chamfered threads on the end of the tap.Will not cut full threads. This set of taps are designed for general use.
With 3 to 5 chamfered threads. BOTTOMING taps with 1 to 1 chamfered threads for tapping to.

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.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.
Recess and slot pattern of dies allows use with a variety of die stocks. The chamfered side of the die is used for starting the threading operation. The end of the piece to be threaded to make angles starting easier. Chamfer also helps in starting at right to the work which is of great importance. The die on the rod with clockwise rotation until it begins cutting onto the work piece.Chips will flow into the holes provided and should be broken by reversing the action. Every 1/4 to 1/2 turn depending upon tightness encountered. Threads of the desired length have been cut.
