i purchased this indexable insert for a milling job and was extremely satisfied with its performance. Based on my experience with Accusize Tools I can say that they produce top-notch products for industrial and scientific use. The carbide insert provided clean and precise cuts and lasted much longer than other inserts I have used before .The only downside is that it is a bit expensive compared to other brands. Nevertheless, I would highly recommend this product to professionals who want to elevate their cutting game..
