Indexable Turning Tools
Indexable turning tools usually come in a set of five tools, providing a range of
cutting angles. These tools use indexable inserts, usually made from carbide,
but sometimes from high-speed steel. They are called indexable because you
can change an insert and the new insert will take the exact position of the
insert it replaces. You can resume work with no further adjustments. Indexable
inserts are pre-sharpened.

4-Jaw Chuck
The 3-jaw scroll chuck that comes with the mini lathe provides a quick way to
clamp round and hexagonal work fairly accurately.
A 4-jaw independent chuck provides several advantages over a 3-jaw scroll
chuck. It can hold square or rectangular work, as well as round. Work can be
centered more accurately because you adjust each jaw independently. It can
hold larger work than the same size 3-jaw chuck. You can offset work in a 4-
jaw chuck by clamping it off center.
