Hi,

I recently bought an ex-demo Axminster/SIEG iKC4 lathe but unfortunately some of the tool parts are missing.

I am new to CNC'ing on a metal work lathe but I need to bore out the centre of a billet with a drill before using a boring bar.

The shanks are 12mm with a flat surface to prevent the boring bars moving when in an internal position in the ATC but I am struggling to find any drill chuck arbors that are also 12mm with a flat.

While I have spoken to the manufacturer and get parts sent over the postage from China is pretty high and I would like to source quicker and more locally if possible.

That said there are several items in the manual that are listed:
B10 Cone collet joint handle (The clamping range 0.6-6)
B12 Cone collect joint handle (The clamping range 1-10)
Joint handle of the collect

Does anyone know where I might source the arbors and indeed what these manual entries mean? (The third entry is the arbour and the first two chucks with their respective mount sizes?)

Also it is possible to buy drill bits with a flat or at least short bits to fit in an ATC. (Making 12mm holes would be all I need for now.)

Thanks in advance if anyone can help.
