Rated 5 out of 5 by from If this machine is as great as its predecessor it will be a great machine. This is the second one of these we have had. I have been at Indiana State University for 35 years and the Model 300 Compact Threading Machine we are replacing has been at the university longer than I. It is a great machine. Jim Gregg

Rated 5 out of 5 by from We especially enjoy the portability. We went from (and still own) the model 690 portable on all our smaller jobs, although a very robust and easy to manage tool it becomes tiresome with all the details of clamping, cutting and threading. The 300 compact has reignited our passion for pipe threading with its ease of use. The only draw back is during transport the sump leaks oil in the vehicle. Not sure if we are missing some details, we believe we are inserting the sump blank off plate properly. We have tried elevating the handle end and oil still finds it's way onto the floor in the Van. If this is the only problem we experience I am certain we will fabricate a nice support stand and call things good.

Rated 5 out of 5 by from Construction Superintendent We are an Industrial Refrigeration contractor and have used Ridgid piping equipment exclusively since my apprentice days.... some 41 years ago. Your product lines have come a long way since the drop head die and ratchet era. All our power vises, tripods, chain vises, pipe wrenches, dies, cutters and reamer continue to be Ridgid, our only choice in tools for our industrial market. To be honest, we've never considered using anyone else's product. Keep making high quality equipment..

Rated 4 out of 5 by from a great machine, except for the plastic parts that easily get broken due to their location on the machine. for example the forward/reverse switch has been replaced about 3 times, the power and foot cord are forever coming out of the housing. other than that it runs and works like a horse.

Rated 5 out of 5 by from easiest threader to use I have own this threader for 3 years now. It's by far the best threader I've used

Can I thread inside threads?

Have recently purchased a Model300 power threader and was wondering if I can cut inside threads and if so what I need to do so?
Asked by: Backyardguy
The model 300 is designed to curt external threads only. We do however offer a selection of manual pipe taps. They can be found at www.ridgid.com or you can contact our Technical Support Department for futher information at 888-743-4333. Thank you RIDGID

What type of grease should be used on the bearings

Page 12 indicates to grease the bearing through the two grease fittings in Fig. 13, but there are no specifications for the type of grease that should be used.
