In my experience disposing of office, lab and workshop equipment, the trade will give you about 10% of the new price, even when almost new. They may be able to resell some of it for several times that but they need to make a living, transport and store, advertise, process sales, pay overheads and tax etc. And much of it will sit there for years.

Hopper is right about business not wanting to mess about with old 1 inch or 25mm lathe tooling.

For the home shop if there is room it is a good reason if you have the room to buy a larger lathe if it is in good working order.

I have never paid more than around 20 Australian dollars for insert tool holders, if there are a few inserts thrown in with the tool that's the value of the inserts.

If it is cheap brazed tooling is OK, you can throw it away when it is dull or resharpen with a diamond wheel. It seems to hold up better with interrupted cut work too, and it can be shaped. My favourite small boring bars are brazed.

I enjoy buying secondhand stuff, often far better quality than new stuff. I was at a classic motorbike event last weekend and bought a J&S lathe tool (1/4" square insert), a small pair of calipers and a depth gauge, about £15 in total. Searching on the Net I found a J&S (Jones & Shipman) company in New Jersey, USA, but also found a J&S (Jones & Shipman) in Leicester UK.
