Center height is everything

A turning tool must present its tip at the exact center height of the spindle. Too high and it rubs; too low and it digs in and the work climbs over it. Shank size and the tool post together set that, which is why they are the first thing to check.

What is not published

Insert designation and geometry. On a light machine, positive-rake inserts ground for aluminum usually cut steel better than the tough negative-rake types, because they need less depth of cut and less rigidity.

The questions welders ask

Indexable or high-speed steel tools?

Indexable for convenience, HSS for very light machines and fine finishes. An insert is turned to a fresh corner in seconds; a HSS tool must be ground, which needs a grinder and a technique. But HSS can be honed truly sharp, which a small, low-power lathe often needs to avoid rubbing rather than cutting.

Why does shank size matter?

Because it must fit the tool post and bring the tip to center height. A 10 mm (0.39 in) shank in a post designed for 12 mm (0.47 in) sits low, and shimming is a nuisance; a 12 mm (0.47 in) shank will not fit a 10 mm (0.39 in) post at all. Measure the tool post slot before ordering.
