Description QS14187J

The M12×1.75 thread repair kit QS14187J is a professional kit for workshops that restore damaged, large-diameter threaded holes. This kit includes everything you need: a drill bit for reaming the hole, a tap for cutting new threads, an insert installation tool, a shank break-off tool, and 10 stainless steel wire inserts.

Stripped M12×1.75 threads are often found in chassis component mounts, brake calipers, engine mounts, as well as in hub thread holes and other critical components. Replacing the entire part can be expensive. The QS14187J completely solves this problem: the hole is drilled, a new thread is cut, into which a wire insert is screwed, restoring the original M12×1.75 size.

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.

Kit contents
