After I put it to the TEST, i must say that I am impressed with this tapered milling accessory. It is a great addition to my collection and has helped me in my industrial and scientific projects. The coated feature ensures it is durable and long-lasting. The precision it offers is remarkable and my cuts have been clean and smooth .However, the only downside is that it is a bit pricey compared to other similar products in the market. Overall, I would highly recommend this cutting tool..
