How to Install a Coil Insert
Drill out the hole with the specified drill
Confirm that the thread and pitch of the bolt match the tap.
Tap the hole with the specified tap.
Set the stop on the installation tool so the tang is centered in the slot.
Wind the insert into the hole with a slight downward pressure until 1/4 to 1/2 turn below the surface.
Remove the tang by placing the tang break tool (or installation tool) on top of the tang and striking firmly with a hammer.
