I was in need for a faster way to create outer threads on plastic pieces. It took too long for me to use a tap wrench.

All models only fit die's with 25mm diameter! Threads can be cut up to 50mm in depth.

You'll need a M4 screw to hold the die's in the adapter.

These adapters come in 3 versions. One with no insert necessary.

One for a ¼" adpater and one for a normal hexagonal bit adapter.

I personally like the version with no adapter necessary, but it's also the biggest model.

Note: Use filaments like PETG, ABS or ASA when you the adapter much. Die's can get pretty hot!

Feel free to leave a like and check out my other models and tools! :)
