Your inexpensive option - you might look on Ebay- would be: A M8-1.25 helicoil installation tool, and a $10 pack of inserts. Don't complicate your life with locking or tangless inserts. For that matter, you could even get by without the installation tool: file the end of a random M8- 1.25 capscrew to look like the tip of the helicoil installer and use needlenose pliers to keep pushing against the insert while installing it. Make sure the insert is installed at least 1/2 thread below the surface, tap against the tang with a screwdriver and break it off (it's prenotched). You might eff up the first insert install- since you're learning- just pull it out (yes rip it out- it wont be reuseable) and try again. You Tube probably has quite a few tutorials on helicoil installation. BTW, the gall resistant coated inserts are for use with SS screws, you are using chrome plated Yam fasteners, just apply blue loctite to the threads to keep from galvanic corrosion.
