I've got a customer in Mississauga, Ontario, Canada...

They would like to buy a HSS or coated tool capable of drilling 8mm, 10mm
and 15mm in closely spaced "steps" on the drill.

Anyone know a good source for such custom tooling? Round shank tooling with
a 0.750" or smaller shank please... If it matters.

Volume is low to medium on this special, simple tool.

How thick is the material being drilled?

Sounds like a Unibit would work if the workpieces are thin enough (which
could be 6 mm on some unibits).
