PreAsion Pipe Threading Machine
#6 in MachinesFull review
A budget multi-function machine with too little published to recommend over the VEVOR. Ask the seller for the motor and weight first.

2.8/5

A RIDGID-compatible 2 in machine at a third of the price, for crews that want the same dies without the RIDGID badge. Check the warranty with the seller first.

A light, powerful 2 in machine for plumbers who carry it up to the job. Pick it over the RIDGID 300 if weight matters most.
