Lisle 12220 Sensor Thread Chaser Review

I replaced the NOx sensor on an Ottawa. The threads were damaged. Thought of changing the hole catalyst. got this tool and it worked like a charm. Saved me a lot of time and money.

The thread has been cut and bent so far that the needle threader can no longer hook the thread to clean it. It kept skipping over topics I wanted to clarify. Useless product. Very disappointed.

A must have for any diesel mechanic You need a regular tap that you can cut off with a regular tap and then use a must have for any diesel mechanic , use this to run both tools together and you're ready for life!

Pulled the NOX sensor out of a box and the filament was with it. This made it possible to recut the hole and fit a new sensor without having to weld on a new connector. worth your money.

The threads have been scored and bent in such a way that the tapping tool can no longer be used to clean the threads. It kept skipping over topics I wanted to clarify. Useless product. Very disappointed.

A must have for every diesel mechanic This is not for cutting, no this is only for cleaning, if you want to tap new threads you need a normal tap you can use a normal one Use faucet to cut them and then use it to clean and beat them up! Every diesel mechanic should have this, use it to run both tools together and you're good to go for a lifetime!
