The Bottoming Tap is used to cut internal threads in holes that do not pass completely through a workpiece. It enables thread formation close to the bottom of a blind hole where standard taps cannot reach due to their tapered lead. Having minimal lead threads allows the cutting action to continue near the base, completing the thread profile along the full depth. The tool removes material progressively as it rotates, forming matching internal threads that allow fasteners to engage fully within the hole.Attributes:• Enables fastener engagement within blind holes.• Removes material to create internal thread profiles.• Forms threads close to the hole's bottom surface.Applications: The Bottoming Tap is used to restore full‑depth internal threads in blind holes. It helps complete thread formation where taper or plug taps cannot reach and supports secure fastener installation in precision assembly and repair tasks.
