Carbide tool holder
John Rudd:
I think it looks like a very cheap,TCMT insert.....the sort bought at car boots for about 50p.....
As said, try winding up the speed, it is cutting on centre height yes?
NormanV:
That was the insert that it came with. I have got some others with chip breaking grooves in them I'll try them tomorrow, I've got a load of cooking to do today.
I tried it on the fastest speed and yes, it is a centre height.

It does indeed look very much like there is no actual cutting insert and just the shim/anvil present in the photo....OZ.

Norman, does the screw that locates what your are using as an insert have a centrally drilled and tapped co-axial hole? If so your are cutting with a carbide seat, and the cutting insert is not fitted ! It would be located by a second screw into that hole.
Usually the insert top surface is pretty well level with the top of the holder which is another clue that the insert is not fitted.

:doh:
I've never seen a carbide tool holder up close before. It certainly is as mentioned by others.
I've been wasting my time with this holder, with it in its lowest position the support piece is exactly on centre height. I need to take another 3-4mm off the height of the holder.
Where can I buy the fixing screw to hold the cutter? I don't have any screws that fit.
I'm glad I posted my story, I would have carried on groping in the dark without your help. Thank you all.
