Knurled Ring
Extend the length of your tap to access hard-to-reach areas. These extensions are for use with tap wrenches and tap holders for drill presses and milling machines.
Extensions with a knurled ring adjust to fit a broader range of tap sizes than other extensions.
Extensions with an included hex key have a close-fitting deep socket and two set screws to hold the tap securely in place.
