The Bottoming Tap is used to cut and complete internal threads in pre-drilled holes, especially where threading must extend close to the bottom of a blind hole. It follows initial thread formation created by taper or intermediate taps and continues the threading process to achieve full depth engagement. The tool removes material in controlled increments as it advances into the hole, forming threads that match the required fastener profile.Attributes:• Assists in completing partially formed thread profiles.• Forms threads compatible with standard fasteners.• Guides cutting path along the interior surface.Applications: The Bottoming Tap cuts and completes internal threads in blind holes to enable full-depth fastener engagement in components requiring threading close to the hole bottom.
