Design your custom tools specifically for your application

Porting Tools

Porting Tools, aka Port Contour Cutters,  are designed to enlarge a pre-drilled hole, usually to produce a more complex form from the existing pilot hole. This cutting tool allows for a precise fit in the port you install into your workpiece and often see usage in both lathe and milling applications. Porting Tools are ground between centers for perfect concentricity. Like all custom tooling ordered from Valley Tool Inc., your custom porting tools will include unbeatable accuracy and precision, no minimum order volume, and the fastest lead times in the industry.
