4 stars. I took one to wrap because when I opened the box, an insert popped out god knows where. It could be a little better, but other than that it's perfect.
Pros
To fit our 1/4" or 5/16" Mini Turning Tool Holder Set or other brand carbide inserts of the same size, please find Asin: B07N2CZQKQ or B07SX1CYYZ to buy the set directly.
