螺紋刀頭與中心規

The high-speed steel feels solid and holds up well on tough materials. Being able to switch between the two offset ends makes threading close to a shoulder effortless. It's a simple tool that does exactly what it's supposed to do.

The dual offset ends are exactly what I needed to reach tight spots near a shoulder on a recent repair. Cut through the steel cleanly and held its edge throughout the job. Definitely worth it for this kind of precision work.

Finally got around to using this in the lathe, and the offset ends made it dead simple to cut threads right up against a shoulder. The steel feels solid and took a good edge without any trouble.
