How to Use a Tap Extension Tool

Extend Your Reach to Tap in Hard-to-Reach Locations

Our Tap Extensions are precision-made tools each designed for a specific size of tap. The end of the extension is a reamed hole made to accept the standard round shank of the tap. If the shank of the tap is not perfectly smooth, it should be polished to fit easily into the extension. These tap extensions are intended for machine or hand tapping operations. Be sure the tap is held firmly in place by making use of both socket set screws. This precaution will aid in positive alignment for machine tapping.
