Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The two-sided design lets me switch between internal and external threads without changing tools. The HSS inserts held up well on stainless steel.

Joshua F. ★★★★★

The dual-end design is a real space-saver—I can flip it for internal threads without swapping tools. The triangle inserts seat firmly and hold a crisp edge through a few test passes on steel, and the 1/2" shank fits my holder perfectly.

Thomas ★★★★★

The triangular HSS inserts cut threads cleanly, and being able to use both ends for internal and external work saves a ton of time on the lathe.
