Keller Machine specializes in fast turnaround custom 3D machining. Our prototypes are made to your exact specifications in short order. Nights and weekends are our normal work times. Some customers come to us on a Friday and get their parts the following Monday (when we can deliver them ourselves!). Short run production or rework is something we also excel at! We are also Licenced by the ATF for firearms manufacture, which opens our customer base and allows us to make parts that other shops cannot legally make.
