B?llhoff in Bielefeld was a supplier to me in a previous lifetime - from memory the most impressive thing I remember was the manufacture of Helicoils.


I've just checked out their Website & they don't appear to have "Sets" for us little 'uns.
Shame it would have been nice to have a supplier a bit more "local" to me.

Alex, John et al.

The Tool worked fine for M8 steel rivnuts. Inside the tool is a proper thrust bearing so that the turning force is not "wasted" in friction. The end fitting is hardened steel with a radial "knurl" that grips the head of the rivnut and stops it turning. Impressive quality tool and made in Britain.

For M8 & M10, it says to use a spanner on the end of the tool (not just the knurled gold wheel) and this worked perfectly.

I bought M8 & M6 kits. Later M4. Speak to the seller, very helpful

Regards
