This Laser Tools Thread Chaser (8412) is designed for automotive technicians and DIYers needing to clean and restore internal M22 x 1.5 threads, particularly in NOx sensor ports for Mercedes-Benz and Vauxhall Opel vehicles. Its key benefit is providing a precise and efficient way to clear debris and repair minor thread damage, saving time and preventing costly component replacement. A potential caveat is its specific thread size, requiring confirmation that M22 x 1.5 is the correct requirement for the task at hand. Key features include its robust chrome vanadium construction, a holding O-ring, and its suitability for use with standard sockets.

This Laser Tools Thread Chaser is specifically designed for M22 x 1.5 internal threads.
It is frequently used for NOx sensor ports on Mercedes-Benz and Vauxhall Opel vehicles, but is suitable for any M22 x 1.5 thread.
You will need grease to apply to the tool and a 7/8" (22mm) socket or spanner to operate it.
The rubber O-ring helps to hold the chaser securely in the socket or spanner, reducing the risk of dropping the tool while it's in use.
This thread chaser is designed for cleaning and minor thread repair. It may not be effective on severely damaged or cross-threaded components, which might require professional thread repair or replacement.
After use, clean off all grease and debris using a brush and suitable cleaner, then dry thoroughly to prevent rust and maintain its effectiveness.
The total length of the thread chaser is 50mm.
Ensure you are using the correct M22 x 1.5 thread size and that the thread port is free of large obstructions. Verify you are turning the tool in the correct direction (usually clockwise to clean internal threads).
Apply more grease to the chaser's cutting edges. Ensure the thread is not severely damaged or cross-threaded, which may require more aggressive repair or replacement.
Use a higher-viscosity grease and ensure it is evenly applied across the entire cutting surface of the chaser.
Inspect the tool for signs of excessive wear. Clean and re-grease thoroughly. If damage is significant, the tool may need replacement to avoid further damaging the threads.
Setup: No complex setup is required. Ensure the thread chaser is clean before use. Apply a generous amount of grease to the cutting edges of the tool. Insert the thread chaser into the M22 x 1.5 threaded port. Attach a 7/8" (22mm) socket or spanner to the external hex drive of the chaser.
Compatibility: This tool is specifically designed for internal M22 x 1.5 threads. It is commonly used for NOx sensor ports on Mercedes-Benz and Vauxhall Opel vehicles but can be used on any M22 x 1.5 internal thread application. It requires a 7/8" (22mm) socket or spanner for operation.
Care: After each use, thoroughly clean the thread chaser by removing all grease and debris. A small brush can be helpful. Rinse with a suitable cleaner if necessary and dry completely. Store in a dry environment to prevent corrosion. Reapply grease before the next use to protect the tool's sharpness and efficiency.
