When producing interlocking components, the ability to add threads to your workpieces is essential. The production of threaded components has come a long way with the popularity of computer controlled milling systems. Thread milling with solid carbide end mills is one of the fastest and most accurate ways to create clean threads without having to worry about damaging your workpiece.

For decades, most threaded components have been completed using tap and die tools. These thread cutters are still used in some situations, but they come with their own issues. Not only is the use of tap and die tools time consuming, but tool failure can have devastating results. The breaking and proper removal of chips cause these tools to experience jams and breaks more frequently than other methods of thread production.

Instead of having to slowly work specialized tools to cut threads, specialized end mills can get the job done in seconds. There are several different varieties of tools for thread milling, with each serve their own unique purpose. Full form thread mills are the best option for fast base production, as they can complete an entire threaded surface in one 360 motion.

For more delicate thread work, single pitch thread mills are a great option. These smaller tools have a single cutting point. This means that the tool has to travel along the entire length of the threads grooves. This will increase manufacturing time, but makes it easier to thread surfaces with thin walls or delicate surfaces/overhangs. You can also use these mills for mixed production when several different thread sizes have to be cut.

When it comes to the manufacturing of your end mills, thread milling with solid carbide tools will produce the best results. Carbide cutters are harder, less flexible, and more dense than steel tools. All of these qualities make them better suited for thread milling, a process that requires extreme precision. Their rigid structure helps to prevent the tools for oscillating or drifting too far off of their cutting path, which helps ensure smooth milling.

Because carbide is a composite material made by combining metal and ceramic powder, the edges of the tools don’t suffer the same fatigue during machining. The edges on metal tools can wear down, but the ceramic edges of carbide tools resist heat and last significantly longer than tools made with high speed steel alloys.

If you are looking to start thread milling with solid carbide tools, you need to find a quality manufacturer of carbide cutters. Online Carbide is an American carbide tool manufacturer with a wide range of thread milling options. Their thread mills are made from high quality micro grain tungsten carbide tool stock and are coating with a TiAlN coating that helps provide an extra layer of protection against heat and wear.
