Maximum cutting depth determines how thick a material the drag knife can cut in a single pass, directly impacting the range of applications for the tool. A greater cutting depth is beneficial for handling thicker materials such as foamboard, cardboard, or composites, while a shallower depth may suffice for thin vinyl or paper. Most Donek drag knives, including the D1 Drag Knife and D3 Drag Knife, feature a maximum cutting depth of 1/4 inch (6.3mm), offering versatility for many common projects. Having a consistent and sufficient cutting depth across models ensures you can tackle a wide range of materials confidently.
