HOW TO USE:

• Prepare the Hole: Using a drill bit with the recommended size of 25/64", create a clean, straight hole in the material you wish to tap. It is crucial that the hole is not oversized, as this will prevent the tap from cutting a full thread.
• Align the Tap: Place the tip of the Irwin 7/16"-20 NF HCS Fractional Tap into the prepared hole. Ensure the tap is perfectly aligned at a 90-degree angle to the surface.
• Start Threading: Using a tap handle, apply light, even pressure and begin turning the tap clockwise. Turn the tap a half-turn or one full turn.
• Clear Chips: After each half-turn to full-turn, reverse the tap a quarter-turn counter-clockwise to break off and clear the chips from the flutes. This prevents the tap from binding or breaking.
• Continue Tapping: Repeat the process of turning clockwise and then reversing to clear chips until you have threaded the hole to the desired depth.
