Creating threads inside holes in metal is a critical process in manufacturing, ensuring the secure assembly of components in various industries from automotive to aerospace. The method chosen can significantly impact the quality, durability and precision of the final product.
Tapping – The Key Process for Internal Threading
Tapping is the primary method used to create threads inside holes in metal. This process involves rotating a tool called a tap in a pre-drilled hole, thereby cutting threads into the material.
Tapping can be performed manually or with machines, ensuring precision and efficiency. For professional applications, Roscamat tapping machines are commonly employed due to their reliability and ability to handle various materials.
Machine tapping is particularly effective for mass production, ensuring uniformity in thread dimensions. Automated tapping machines, including pneumatic and electric models, allow for high-speed operations, saving time while maintaining accuracy. These machines are designed to work seamlessly across different thread sizes, making them indispensable in industries requiring repetitive internal threading tasks.

Thread Milling – An Alternative for Complex Applications
Thread milling is another process used to create threads, especially when dealing with hard metals or specialised thread profiles. Unlike tapping, which cuts the threads directly, thread milling uses a rotating cutter that moves along a helical path inside the hole. This approach reduces stress on the material, minimising the risk of tool breakage. It is particularly advantageous for large-diameter threads or materials that are difficult to machine.
Thread milling requires CNC or computer numerical control machines to ensure precision, making it suitable for high-end manufacturing sectors like aerospace and automotive. While it is less common than tapping, thread milling is favoured for its versatility and ability to handle materials prone to distortion or wear during traditional methods.
Both tapping and thread milling play vital roles in manufacturing, ensuring high-quality threads for applications across various industries. By investing in the right tools and methods, manufacturers can optimise their threading processes effectively.
