УПОРНЫЙ МЕТЧИК Caterpillar 4C4987

The Bottoming Tap cuts internal threads near the base of a pre-drilled hole, allowing maximum thread engagement in applications where depth is restricted. It follows an initial threading operation performed by a taper and intermediate tap, extending the thread profile closer to the bottom of the hole. This function enables complete utilization of the available hole depth for fastening purposes. The tool engages with the inner surface of the drilled hole and removes material in a controlled manner to form thread geometry. Attributes:• Allows controlled material removal during cutting.• Forms threads for fastening component insertion.• Maintains continuous thread profile formation.Applications: The Bottoming Tap creates internal threads to full depth within blind holes to allow complete fastener engagement in applications where hole depth limits standard threading tools.
