When I tried this product, I was surprised at how easy it was to create precise threads in a variety of materials .The materials used in this indexable insert holder are of high-quality, ensuring that they provide excellent performance and longevity. The holder also has a sturdy design that makes it easy to use even on ROUGH surfaces. One potential downside is that it may not fit all threading needs, but overall its worth a try if you're looking for a reliable tool..
