After trying out a variety of router bits for my metal engraving projects, I stumbled upon this gem. The Industrial and Scientific grade aluminum bit is durable enough to handle multiple uses and provides precise markings every time. The straight cut design allows for clean lines and the sharpness of the bit makes it easy to use on even tough metal surfaces. However, the bit requires careful handling and control to avoid damage or breakage. Overall, a great addition to my cutting tool kit.
