Orion Motor Tech 48 Piece Thread Chaser Set, Metric and SAE Thread Repair Kit with 22 Taps 24 Dies 2 Thread Files, Universal Rethreading Kit Thread Restorer Tool Set in UNC UNF Metric Sizes with Case

I just bought this Thread Chaser Kit and it provides a full complement of S.A.E. and Metric thread pitches that you commonly need for servicing threaded components. This is a really important kit to have in your tool arsenal in checking and properly cleaning threads on bolts, bolt holes and other threaded components. This is important for proper seating, proper torque values and eliminating leaks. If you want a quality thread chaser, please consider picking one of these kits up and enhance your maintenance and service related procedures you perform. OMT equipment is the best in my opinion.

Accidentally stripped a bolt and the bolt hole, this product fixed it with no issues. Perfect for DIY mechanics with a right amount of lube, patience and gentle operation.

This Orion Motor Tech 15-piece metric thread chaser set is a great addition to my toolbox. It does exactly what it’s meant to do: cleans out and repairs damaged bolt and nut threads quickly and easily. The pieces fit well and work smoothly without cutting new threads, which is exactly what you want in a chaser set. I’ve wanted one of these for years and finally took the plunge, and I’m really glad I did. It has already saved me time and frustration on multiple jobs. The set feels well-made and covers a good range of common metric sizes. If you work on vehicles or equipment, this is one of those tools you don’t realize how useful it is until you have it. Highly recommended.

It does what it advertises. It chases threads. fit and finish is good and the thread size and profiles are definitely in spec. Is it snap on quality? No, but its cheap and does it's job well.

Excellent.
