I purchased this item as an industrial and scientific tool for milling non-ferrous materials. As a hesitant buyer, I was excited to put it to the test. However, as a result of my tests, I determined that this product falls short of my expectations. While it is affordable, the flutes spiral too quickly and lack the precision needed for high-quality machining. The one pro is its affordability, but it ultimately doesn't make up for its lack of performance.
