The difference between cutting taps and extrusion taps

The main difference between cutting taps and extrusion taps lies in the processing principle, applicable materials, processing effects and application scenarios

Processing principle
Cutting taps: Internal threads are obtained by removing metal, with flutes, which produce chips. It is suitable for materials with high hardness and low plasticity, such as cast iron or mild steel

Extrusion taps: Threads are processed by plastic deformation of metal, without cutting and chip-free machining. It is suitable for materials with low strength and good plasticity, such as copper alloy and aluminum alloy, and can also be used for stainless steel and low carbon steel

Applicable Materials
Cutting taps: suitable for materials with high hardness and low plasticity.
Extrusion taps: suitable for materials with low strength and good plasticity.
Processing effect
Cutting taps: During the processing process, part of the metal streamline will be destroyed, the thread strength is low, the surface has cutting lines, and it is not too smooth

Extrusion tap: The thread is formed by the plastic deformation of the metal, which does not damage the metal fiber, the thread strength is high, the surface is bright, and there is no cutting pattern.
Application scenarios
Cutting taps: suitable for a wide range of processing of various materials and non-metallic materials, cutting is light and fast, and has a wide range of applications

Extrusion taps: suitable for ductile materials, stable processing, better quality and longer life, but difficult to produce and high cost.
