КОНИЧЕСКИЙ МЕТЧИК Caterpillar 4C4998

The Machine Screw Taper Tap helps begin internal threading by using a tapered lead that gradually shapes the first threads inside a drilled hole. This slow engagement helps improve tool alignment and reduces the chance of cutting the threads at an incorrect angle. The tool supports a controlled start that makes it easier to complete the thread with plug or bottoming taps. Attributes:• Helps start threads in drilled holes reliably.• Tapered lead provides smooth cutting entry.• Reduces thread start deformation.Applications: The Machine Screw Taper Tap is used to initiate threading in drilled holes before final threading stages, helping ensure reliable screw engagement in service and workshop environments.
