Shank size is a crucial consideration when selecting a Donek Tools drag knife because it determines compatibility with your CNC router’s collet. The most common shank sizes in the Donek Tools lineup are 1/2 inch and 1/4 inch, which fit the corresponding collet sizes found on most CNC machines. Choosing the correct shank size ensures a secure fit and optimal tool performance. For example, the Donek Tools D1 Drag Knife 1/2 SHK is ideal for machines with a 1/2-inch collet, while the Donek Tools D4 Drag Knife 1/4 SHK is perfect for 1/4-inch collets. The availability of both sizes allows users to select the best fit for their equipment, offering flexibility and ensuring safe, accurate operation.
