УПОРНЫЙ МЕТЧИК Caterpillar 4C4986

The Bottoming Tap creates internal threads at the base of pre-drilled holes where full thread depth is required. It follows initial threading operations performed by taper and intermediate taps and continues cutting threads closer to the bottom of the hole. The tap advances into the hole while removing material to form defined thread profiles that match mating fasteners. The tool operates by rotating within the drilled hole, with its cutting edges progressively shaping the internal surface into threads.Attributes:• Advances into the hole during rotational movement.• Removes material to create thread grooves.• Facilitates matching with external threaded fasteners.Applications: The Bottoming Tap cuts full-depth internal threads in pre-drilled blind holes to enable complete fastener engagement within limited hole depth during fastening operations.
