Hi, I’ve a couple of chaincase studs that require helicoil to recover them. Any recommendations of decent helicoil kit ?

My own kits range from M5 up to spark plug size & have mostly been genuine Helicoil which came up for sale @ the right prices. I think my M7 kit is V coil which has also been as good as Helicoil branded.

I've bought replacement inserts from eBay which were fine in the M5 size. They were made in China.

You will find bargains on eBay which will also have been made in China. I think that if you can buy from a UK based supplier, it will be more quickly received, though a bit more expensive.

In fact, I had a look on eBay but the only thing that would put me off is the insert length. They seem to all come with 1.0 D inserts which is only 6 mm for an M6. If I'm repairing threads in alloy, I want the longest insert that will fit or a minimum of 1.5 D. In the case of M6 that is 9 mm, which still isn't a lot, but should be fine.
