Can I use it without a die holder?
Yes—drive it directly with a ring or open-end spanner on the hex body.
Will it cut a new thread?
It’s primarily for rethreading/repair. For cutting new threads from scratch, use a round adjustable die in a die stock.
What lubricant should I use?
Use quality cutting oil or paste appropriate for the base material to improve finish and tool life.
How do I avoid cross-threading?
Start square, use gentle pressure, and feel for proper lead engagement. If it binds, back off and realign.
Is HSS right for general maintenance?
Yes—HSS offers good toughness and reduced brittleness, making it a solid choice for day-to-day repair work.
