What Is a Thread Mill? Understanding Thread Milling Tools for CNC Machining
A mold-making shop recently approached us with broken taps embedded in pre-hardened tooling blocks. Tapping seemed economical for the initial low-volume run, but rapid tool wear quickly caused rough surface finishes, torn pitches, and catastrophic tool failure. When a tap breaks inside an expensive cavity, EDM burning is often the only extraction method, inflating production
