About Extension Taps

Extension Taps are a type of Threading Tool that is used to cut threads into the internal surface of a hole or opening. They are used to create new threads, repair existing ones, or even enlarge them for larger fasteners. Extension Taps can be used in many industries such as automotive, aerospace, and oil & gas.

Types of Extension Taps

Extension Taps come in several different types including Spiral Pointed Extension Tap, Spiral Flute Extension Tap, Bottoming Extension Tap, and Plug Type Extension Tap. The type chosen will depend on the job requirements and what material is being tapped into.

Materials Used for Extension Taps

Extension Taps are typically made from high-grade steel or cobalt alloys that have been heat treated for strength and durability. This allows them to be able to handle higher torque loads while still being able to maintain their cutting edge.

Industries That Use Extension Taps

Extension taps are commonly used by professionals in the automotive, aerospace, and oil & gas industries. They use these tools to tap threads into engine blocks or other components where a tight seal is needed. They also use them when enlarging existing thread holes so they can fit larger fasteners.
