thanks again!
The tools sit on a carbide pad that is on a helix angle to give the tool some additional clearance it the direction of travel.
If you're producing a LH thread, your direction is reversed so you need the correct anvil.
Control the process, not the product!
Machining is more science than art, master the science and the artistry will be evident.
