Shank diameter is a vital factor when selecting a CNC Drag Knife, as it directly affects compatibility with your CNC router’s collet. A correct shank size—commonly 1/2 inch or 1/4 inch—ensures the knife fits securely, reducing the risk of slippage and promoting both operator safety and cutting precision. Using the proper diameter also helps maintain tool longevity and stable performance throughout your project. Donek Tools Drag Knives are available in both 1/2" and 1/4" shank sizes to accommodate a wide range of CNC machines. For instance, the Donek Tools D1 Drag Knife features a 1/2" shank for larger collets, while the Donek Tools D3 Drag Knife is tailored for 1/4" collets. By selecting the shank diameter that matches your CNC router’s collet, you ensure optimal performance, safety, and compatibility with your equipment. Donek gives you uninterrupted service when a project has to be finished on time.
