Breaking a screw extractor is not something you or your technicians want when making an exhaust repair. Unfortunately it happens and can turn a repair from minutes into hours. As a solution, ProMaxx designed the Broken Extractor Removal Kit to save technicians time. The kit includes ProDrill Platinum PLT tooling (SML) and ProMill PPM125 machine grade tooling. The kit is designed to first flatten the extractor, then bore through the broken extractor to remove it completely.
