Can someone give me a link to a tutorial or easy to understand description of indexable lathe tools so I can make sense of whats on offer on fleabay. I need to replace the tooling on my lathe and in the past I have ground my own tools but thats been for very basic turning operations on soft metals. Rather than acquire some more HSS toolstock and apply my moderately hamfisted attempts at making tools I thought I'd progress to either ready made brazed carbide tools or indexable tipped tools...

Any constructive views on one v the other and where to purchase cheaply?
