The BOA RTR 2 is like no tool you have ever used, this thread repair tool gives fast precision to any damaged thread (internal or external) it comes into its own either on site or in the workshop, it re-seats and profiles all sizes for thread and pitch. The patented self-aligning head fits a standard variable drill or air-tool and with a steady hold you just walk the tool through the thread. The RTR 2 head is constructed using industrial diamonds that are vacuum brazed to a balanced shaft, this too is a marvel in that it will repair over 150 different size threads from 20mm through 200mm.
