УПОРНЫЙ МЕТЧИК Caterpillar 4C4977

The Bottoming Tap forms internal threads within pre-drilled holes, allowing fasteners to engage securely at full depth, especially in blind hole conditions. It follows initial threading operations performed by taper or intermediate taps and extends the thread profile closer to the base of the hole. The tap features minimal lead threads, enabling it to cut threads near the bottom without leaving unthreaded space. During operation, it removes material in a controlled manner to generate a thread pattern that matches the corresponding screw profile.Attributes:• Supports full engagement of threaded fasteners.• Removes material to create an internal thread pattern.• Allows formation of threads without excess clearance.Applications: The Bottoming Tap cuts internal threads to full depth within blind holes to allow complete engagement of screws during fastening operations where limited hole depth is available.
