What do these fit
Does any one who has been the game for a long time recognise what these are and what tool holder they fit...i am thinking a parting off bit?
Cant find a reference to in the Travers book.

Definitely look like parting/grooving inserts, quite possibly obsolete

https://www.travers.com/category/par...ooving-inserts and https://www.ausee.com.au/shop/category.aspx?catid=8265
They are a double ended Grooving Parting Insert. They would fit something like the toolholder is the Ausee link. I found other pictures on the internet by Googling 'double ended lathe grooving parting insert' but none of the pictures that I seen showed an Insert with a notch or cut out in its lower part. Having the notch they may have been meant for a specific holder. Someone else may be able to help you further. All the best for the New Year.All The Best steran50 Stewart

No they won't, that style of tool holder uses inserts that have a V-groove along the top and bottom and the cutting edges can't be higher than the rest of the insert because they won't clamp.
Found some similar at work in a drawer during cleanup and we just threw them out because nothing uses them anymoreGear cutting specialists and general engineers www.hardmanbros.com.au

Hence why I stated 'SOMETHING LIKE' meaning they won't necessarily fit that holder itself, but something like it.

Sorry missed that. I still say they're obsolete, never seen anything like those in any current catalogue.

Could they be cutters for a head in a Radial Arm Saw for cutting Trenches across a 4 X 2?
What is the measurement across the double? If its 52 or 35mm I reckon its from a Trenching HeadJust do it!
Kind regards Rod

I am speculating that I reckon they are lathe stuff as when my bro left the govt many years ago he had accumulated a bit of HSS and other lathe tools. This was among all that stuff. I ended up with it when we cleaned out Dads shed as bro didnt have a use for it...he was always wanting a lathe but never got around to it.
