Cutting length defines how deep the bit can cut into the material in a single pass. The best cutting length depends on your material thickness and application—shorter lengths provide better rigidity and less deflection for fine detail work, while longer cutting lengths allow for deeper cuts or thicker materials in one pass. For instance, the 51405-K (1” CH) is suited for thicker plastics, while the 51411-K (1/2” CH) is ideal for moderate depths. Selecting from various cutting lengths ensures you can match the bit to your specific material and project requirements when choosing cnc bits for plastic.
