Maximum cutting depth determines how thick of a material you can cut in a single pass with your CNC Drag Knife. This is an essential factor if you plan on working with thicker substrates such as foam board, leather, or certain plastics. A typical maximum cutting depth for leading models like the Donek Tools D2 Drag Knife and Donek Tools D4 Drag Knife is 1/4" (6.3mm), which is sufficient for most hobbyist and professional applications. Having options with the same robust cutting depth across different shank diameters allows users to select the best knife for both their machine and project thickness.
