The Metric Sized Individual Plug Tap forms internal threads within a pre-drilled hole by cutting material along the inner surface as it rotates. It engages with the hole using its cutting edges, progressively shaping the internal profile to match the required thread form. This process allows threaded fasteners to be inserted and engaged within the hole for fastening purposes. The tap advances into the hole while removing material in a controlled manner, creating helical grooves that define the thread structure. It allows alignment with the drilled hole axis, enabling consistent thread formation along the depth of the hole. Attributes:• Cuts internal threads within pre-drilled holes.• Forms helical grooves along the inner hole surface.• Engages cutting edges with material during rotation.Applications: The Metric Sized Individual Plug Tap is used to cut internal threads inside pre-drilled holes to enable the insertion and engagement of threaded fasteners for fastening and disassembly during maintenance or assembly operations.
