Is the PC 7424 the most durable detailing tool?

I cannot say the same about various angle grinders (rotaries) I have used.

What is interesting about this statement is that it made me think...

When either the Dynabrade #61374 Random Orbital Head or the #61379 Dual Action Buffing Head is run up to the recommended speed, they top out at around 3,200 RPM.

So...
A grinder is a rotary is a random orbital in this case. :biggrin: It all depends on the attachment!

I wonder if I can buy a drill bit set with threads that fit a 5/8-11 shaft?! :out:

"Umm, yeah hi. Listen- I need to buy a replacement 4mm drill bit for my rotary drill bit set. Can you help me?!" :cursing:
 
Just to clarify my statement to my knowledge rotaries are primarily the same as rotary buffers by design. A tools intended use is really nothing more then marketing: a rotary is the same as an angle grinder like a dual action sander is the same as a dual action car polisher. The difference is often the box we buy it in.

We all have opions on what is best and as long as opions are shared respectfuly they are free to be shared.
 
what a good thread In the last 11 years I had probally at least 7 rotory buffers 1 remington ill be surprised if anyone has used this one. 1 milwalkee 1 makita which i now miss and im on my 4th dewalt. I bought 1 pc 4 years ago and still works the same as the say i bought it. I just now purchased the new as a back up. And my newest purchase was a gear driven pneumatic d/a. which is the newest toy. I was always taught that a pc can never do what a rotory can. all these years i was using my pc a tool to speed up the wax and sealent process now my dewalt has been collecting more dust then the pc. times have change, yet the pc hasn't. hands down its the most durable!
 
Bryan - getting back to your question regarding durability of the PC ROB, I've had mine for probably 6-7 years now and have used it on hundreds of cars without ever having a problem. When it was my sole correction machine It didn't see speeds less than 5 and mostly 6 and I've been through maybe a dozen BP's.

Since my move to a rotary machine for correction it now only sees use for AIO's and LSP's (and at lower speeds) so I've been easy on it since the rotary became the "new Sheriff in town" however I've never even had a chord problem.

I'm curious to hear some of the stories from the other side of experience with this thing i.e. lack of durability and the user conditions that warranted it's demise.

Other than maybe a boat detailer dropping one in the drink it sounds like it's been run over and dropped on concrete and still runs like a Timex!

Don't know how this triple posted but I apologize if it was my fault for some reason. Please delete as you wish.

That does seem to be the question here.... Other than the old (non-UL-approved) UDM, has anyone here ever had a PC fail???
 
Was polishing a car yesterday when my 7424's opms went to about 25,000!!
I was buffing a plastic bumper at the time and lifted it off in a hurry, luckily no damage to the bumper. When I rotate the speed dial from 1-5 there is no change in speed, but when I hit 6, it takes off. Time to get the 7424XP as this buffer was 3 years old and out of warranty.

Sounds likes a problem with switch and not from misuse.

That is what I think because before it happened I would spread product around on speed 1, turn off, dial up to 6 and turn back on and sometimes nothing would happen. I had to turn on and off to get it to go. I've probably only used this on about 10 cars since I purchased it. It is out of warranty, should I try and fix it myself or take it to a Porter Cable repair shop and hope it costs less to fix than a new one? At the speed it now runs on 6, I'll bet it will be like KBM on steroids!!:w00t:
 
Excellent feedback, I have had my PC for 6 years. I use it monthly on boats and cars. Question to you experts; what is the relationship of the numbers on the setting wheel to RPMS? Is it linear? i.e. setting 3 equals 3000 RPM?
Thanks for your attention
 
OK guys help me out here, if the pad on your machine is going to change direction does that not mean that the motor rotation must also change direction?
