RIDGID 1215 61142
#3 in MachinesFull review
A compact 1-1/2 in machine for crews that thread small gas and water lines all day. The 300 does more for about the same money.

3.1/5
The only 4 in machine here that runs on a 110 V outlet. Choose it for a shop that threads large black pipe and sprinkler mains.

#4 in MachinesFull review
A budget 2 in machine for a home shop or an occasional contractor. It does the job slowly without the support network of RIDGID.

A budget multi-function machine with too little published to recommend over the VEVOR. Ask the seller for the motor and weight first.
