the store couldnt tell me.
Assuming it is not HSS:


If the store can't tell you, then it's not high-speed steel. In fact, you'll
be lucky if it's really drill rod, and not plain cold-rolled mild steel. Is
it ground on the outside, or just dull silver?

Do you have a bench grinder? If so, someone here probably can direct you to
a site that illustrates spark tests to determine steel grades. The standard
grades aren't hard to tell apart.
