Thread repair kitM4x0,7 V-COIL

V-COIL thread repair kit
Drilling: drill the damaged thread with an ordinary twist drill. No drilling is required for spark plug threads; In this case, a drilling and notching tool is used. Please note that larger holes are required when kneading the thread.
Check: check that the tap and threaded pins match in thread and stroke.
Thread: use a special V-COIL tap to cut the thread into the drilled hole. It is recommended to use oil for machining.
Thread insert mounting: Attach the insert to the tool, making sure the pick-up pins are placed in the tap grooves, then adjust using the adjustable ring. Screw the insert in accordance with the thread coil under light pressure.
Do not rotate in the opposite direction to the screwdriver, as the journal may break.
Pinch breakage: after mounting, remove the tool and remove the pivot with a tenon breaker. For larger dimensions and with spark plug threads, the pivot is pulled out with pliers with narrowed ends. Thanks to tight and accurate tolerances and the forming process, a thread is created at the end of these operations, which is often better and stronger than the original thread.
Application: thread reinforcement from materials with limited shear strength, e.g. aluminum and magnesium alloys, application in machine manufacturing, automotive, electrotechnical, medical and aerospace industries, repair of damaged or worn threads, reuse of defective product.
