what is the thread milling process?
Thread milling is the process of cutting a thread with a rotating cutting tool with a specific form to suit the thread you require. This is an alternative method to tapping a hole, but unlike tapping, thread milling is used on larger holes and works on both internal and external threads. Thread milling is typically a more accurate and precise way to create a thread as the depth of the thread can be accurately controlled.
Thread milling comes in particularly useful when either a large thread, an external thread, or an accurate thread is required. Threads can be cut with a tool offering various numbers of teeth where some applications use a thread mill offering a single point, some offering 15-20 teeth and some being indexable inserts that are screwed onto the end of a reusable steel shank.
The main benefits include:
Better thread quality than tapping, as it offers a better chip evacuation.
A flexible tool, where the same cutter can be used to produce both internal and external threads.
Threading in difficult-to-machine materials, such as HRC 65 and titanium.
Threading in blind holes - thread milling produces a complete thread profile from the top to the bottom of the hole.
