The Bottoming Tap cuts internal threads in pre-drilled holes, allowing thread formation up to the full depth of the hole. It features a minimal lead at the cutting end, which enables threading close to the bottom surface without leaving uncut sections. This function is used after initial thread formation by taper and intermediate taps to extend threads deeper into the hole. During operation, the tap rotates within the drilled hole, and its cutting edges remove material to form thread profiles along the internal surface. The reduced lead length allows cutting edges to engage quickly, enabling thread creation near the base of blind holes.Attributes:• Enables thread formation up to full hole depth. • Features minimal lead at the cutting end section.• Removes material to form the thread profile shape.Applications: The Bottoming Tap is used to create internal threads to full depth in blind holes after initial tapping stages to enable complete thread formation for fastening applications.
