Why do I need to upgrade?
The Dewalt DW610 has not been manufactured sense Jan. 1 2003. This includes the BD3315 and all other Dewalt products that use the same family of castings. The router that Dewalt is building to replace the DW610/612 is the DW616/618. The DW616 has all new castings. However, the diameter of the router motor is the same as the DW610. That means that the DW616 can be used in the same router base as the DW610 and it will retrofit into most applications where the DW610 and BD3315 were used. There are a few things about the DW616 that keep the retrofit from being a direct replacement in this application.
