This milling tool exceeded my expectations! After I put it to the test, I was blown away by its durability and precision. It has a strong titanium build that allows it to take on tough materials with ease. The ability to engrave and drill at varying depths with one tool is a great convenience. Plus, the 1.5-3.175mm range makes it versatile for a variety of projects. The only downside is the price but for industrial and scientific use, it's worth the investment. .
