УПОРНЫЙ МЕТЧИК Caterpillar 4C4982

The Bottoming Tap creates internal threads within pre-drilled holes, allowing fasteners to engage securely along the full depth of a blind hole. It features cutting edges that extend close to the tip, enabling thread formation near the bottom where standard taps cannot reach. During operation, it advances into the hole while removing material in a controlled manner to form thread profiles that match the intended fastener. The tool follows previously formed partial threads or drilled hole geometry, extending the thread pattern to the base of the hole.Attributes:• Advances in hole using rotational input motion.• Produces internal threads for bolt installation.• Facilitates chip removal during cutting action.Applications: The Bottoming Tap cuts internal threads to full depth in blind holes to enable complete fastener engagement where threading must extend close to the hole base.
