Description QS14187G

The QS14187G M12×1.25 Thread Repair Kit is a professional set for workshops that repair damaged medium-diameter, fine-pitch threaded holes. This set includes everything you need: a drill bit for preparing the hole, a tap for cutting new thread, an insert installation tool, a shank break-off tool, and 10 stainless steel wire inserts.

Stripped M12×1.25 threads are often found in engine component mounts, transmissions, brake calipers, wheel hub threads, and other critical components. Replacing the entire part can be expensive. The QS14187G completely solves this problem: the hole is drilled, a new thread is cut, and a wire insert is screwed into it, restoring the original M12×1.25 size.

Technical specifications

⚠️ Important: Use lubricant when drilling. Make sure the hole is drilled evenly, without skew. The length of the insert must match the depth of the hole.
