حامل، 5C لظرف المخرطة ثلاثي الفك، 4 بوصة

The internal threads lined up perfectly with my chuck’s backplate, and the whole thing tightened down without any wobble. Swapping between collets and jaws is now a five-minute job instead of a wrestling match. I’m glad I grabbed this in the 4” size.

The 5C adapter threaded right onto my existing chuck without any fuss, and the internal threads matched perfectly for holding collets securely. It's saved me a ton of time switching between setups.

Fit the 5C collets into my 4" 3-jaw without any fuss, and the threads are cut clean so it screws on snug every time. Solid steel construction means no wobble during a job, exactly what I wanted.
