131Pc Thread Repair Kit HSS Drill Helicoil Repair Kit 1/4" 5/16" Inch W/Case

Description: Damaged Thread Repair Tool Kit M5 M6 M8 M10 M12 Manufactured from chrome vanadium steel for strength and durability. Ideal for restoring damaged threads in steel, cast, iron and aluminum. Suitable for engine repair and other automotive applications. Drilling - clear the damaged threads with a standard drill. (to repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap), please pay attention that for fluteless taps bigger holes are required. Check - check that the thread and pitch of the tap and the bolt match. Tapping - use the special taps for cutting the holding thread into the cleared hole (recommended to use a suitable cutting oil) Install the insert - place insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot. Wind the insert in with a light downward pressure until a half turn below the surface. Don't work against the thread direction as the tang could break. Tang removal - After finishing lift the installation tool and use the tang break tool to remove the tang. For bigger sizes and spark plug taps use long nose pliers to remove the tang. Due to the narrow and exact tolerances the new thread normally is stronger than the original ones.
