The multi-thread mill can thread a hole more quickly than a standard thread mill. The multiple cutting teeth achieve a very good quality, exact thread in just one revolution. They are not recommended for steel.

Thread milling is when a tool is used to helix and machine either an internal or an external thread. Thread milling offers distinct advantages compared to tapping, such as:

• Higher quality and cleaner threaded grooves
• More control on the tolerance or size of the thread
• Burr-free edges with a bevel to assist with a lead-in

We offer a wide range of micro-grain carbide tools that can create thread sizes as small as 1-64 UNC or M1 Metric threads.
