Not able to continue 1”bspt threading operation since insert is wearing very fast for every 2parts, though tried with lesser RPM up to 500.

It’s an SS pipe and suitable insert only has been used.

Can anyone suggest solutions plz

Maybe your 1st Pass is too big and wears insert.

Try to program same threading shape with same rpm using bigger X starting and end point , about +1,5mm diameter, after this You can finish threading with original X coordinate
