Hi Simon,
Thanks for the response to my query. I really don't know much about this.
Any info would be apreciated ,eg, are there special cutting tools available or do you have to make them up, are ther special inserts for the holes in the toolpost for drills,. I am a complete greenhorn on these so please forgive my ignorance if these are stupid questions.
Regards,
George.

The changer takes 8 tools. 4 of which are regular (radial) tools and 4 axial for boring or drilling.
Both types of tool are held in place with grub screws. You need to pack the radial tools appropriately to set the height.
I made an adaptor with a morse 2 taper which fits in to one of the axial holes to take a drill chuck or morse drill bits. Turning a morse taper is obviously rather easy with CNC - but you can buy morse reamers.
Alternatively, you can put a slot-drill (mill cutter) in the axial tool holder to drill flat bottomed holes - but better than that, by moving it off axis, you can drill a flat bottomed hole bigger than the cutter size and even use it to face off the end of the billet.
