Description

V-COIL thread repair assortment Drilling: Bore out damaged thread with normal jobber drills. Boring out is not required for spark plug threads - the combined drilling and cutting tool should be used. Please note that larger holes are required for taps. Check: Check the tap and thread bolt for the same thread and gradient. Thread: Use the special V-COIL taps to cut the mounting thread into the drilled hole. The use of cutting oil is recommended. Install threaded insert: Place the insert onto the installation tool, ensuring that the tang fits into the notch. Then adjust the setting ring correctly. Then turn in the threaded insert in the thread direction applying light pressure. Do not turn against the running direction, as the pin can break off. Tang removal: After installation, remove the installation tool and break off the tang using the tang break-off tool. The pin should be removed with long nose pliers for larger dimensions and spark plug threads. After completing these steps, a thread is produced that is often better and stronger than the original thread due to the narrow and exact tolerances as well as the spring thread forming. Application: Thread reinforcement of materials with low shear strength, e.g. aluminium and magnesium alloys, in mechanical engineering, automotive, electrical and medical engineering as well as in the aerospace industry. Thread repair of damaged or worn threads. Reject recovery. Scope of delivery: In plastic case, manual installation tool with locking ring, twist drill in core hole dimensions, tap and thread inserts (1.5 x D).
