As a hesitant buyer, I was unsure of investing in an Industrial and Scientific cutting tool but the results from my tests showed that this Forstner bit exceeded my expectations. The precision and smoothness of the cut made my woodworking projects a breeze. The carbide material proved durable and long-lasting .The only con I found was the price, but as the saying goes, you get what you pay for. i highly recommend this product to any professional or hobbyist in need of high-quality cutting tools..
