In the world of machining, creating internal threads can be achieved through various methods. Two of the most common techniques are tapping and thread milling. Each method has its own advantages and disadvantages, making them suitable for different applications and materials. We examine the pros and cons of tapping and thread milling to help you choose the right method for your needs.
The Pros and Cons of Tapping
Pros:
Speed – Tapping is generally faster than thread milling, making it ideal for high-volume production runs.
Simplicity – The process is straightforward, with taps being easy to use and requiring minimal setup.
Cost-Effective – Tapping tools are typically less expensive than thread milling tools, which can reduce initial investment costs.
Cons:
Tool Breakage – Taps are prone to breakage, especially in harder materials or when machining deep threads. This can lead to production delays and increased costs.
Flexibility – Tapping is less versatile than thread milling, as each tap is designed for a specific thread size and pitch. This means that multiple tools are needed for different thread sizes.
Material Limitations – Tapping may not be suitable for certain materials, such as very hard or brittle substances where the risk of tool breakage is high.

The Pros and Cons of Thread Milling
Pros:
Versatility – According to SME,thread milling is highly versatile, allowing for the creation of threads of different sizes and pitches with a single tool.
Tool Life – Thread milling tools generally have a longer lifespan than tapping tools, especially when machining harder materials.
Reduced Risk of Breakage – The cutting forces in thread milling are lower, reducing tool breakage and damage to the workpiece.
Cons:
Complexity – Thread milling requires more complex programming and setup, which can increase the initial time and cost.
Speed – Thread milling is generally slower than tapping, making it less suitable for high-volume production.
Cost – The initial investment in thread milling tools and the required machinery, such as specialised CNC machines, can be higher.
