Hope it is gone for good,

We have the 'upgrade for your convenience' of the M27 to look forward to. One of the diversion routes is past our front door.  :hammer:

Used carbide drill bits with a 1/8" shank can be had off Ebay for less than a buck a piece.  These can be used to make a variety of small tools, both external tools and internal.

Nice insert Bill, that's given me ideas for my own tooling cut from hacksaw blade.  Times like this I wish I had an EDM machine  :thumbup:

Side on it's triangular with a hole in the middle.

Ideally it needs to sit in a V open at the bottom . It's not difficult to make if you have a mill.

Bill,
That’s a great gesture….I’ll bear it in mind. Does it need a holder of some sort?

In the meantime, I’ll give some other ideas a go…

I found a used carbide grooving insert 0.75mm by my measurement.  Might have one good edge, or would sharpen on a diamond lap.

Just wish the silver steel wasn’t so hard!

Sounds like a good approach to getting it sorted.

Steel is not hardened…

I’m thinking using a broken 1/8” centre drill suitably profiled to make the groove, sharpened on my t and c grinder..
