Porter Cable 7336 vs 7424??

What is the difference between these two models?
The 7336 seems to be way cheaper than the other.
TIA

They are the same except for the weight in the head. You want the 7336 that comes with the #6 weight. Lowes for $109 is the best I have found.

The one I bougtht from CMA is the 7424. I thought that was the one most here recommended? What does the weight difference do?
Thanks,Bill

7424 at Coastal is $115......get the pads at CMA...7424 needs the
weight because that offers the orbital motion....but I had to buy the velcro backing plate and all the pads...
get extra pads..you'll need it

I think the best thing to do is get the 7336, which comes with the counterweight for the 6", from Lowe's for $109. Then get the CMA pad kit. The 7424 comes with the 5" counterweight, which is ok for the pad that screws right into the orbital, but the velcro backing plate is much heavier than the foam pad that screws in, so the 6" counterweight is more beneficial. And, most agree that the pad that comes with the 7424 is pretty much useless. So, with the 7336, you get the 6" counterweight (which is better), a sander (which comes in handy), and since you have to order a velcro backing plate and pads with either the 7336 or 7424, the 7336 is cheaper.

If you purchase the 7424 you will need to buy the #6 counterweight to use the pad kit from CMA. The 7424 comes with the #5 weight which will not work properly with the 6'' backing plate from CMA

You can buy the 7336 from Lowes with the proper counterweight already installed for $109.

The 7424 and 7336 are the same machine, they are just outfitted differently. The 7336 comes with some sanding stuff in additon to the polishing head, otherwise they are exactally the same.

IMO the 7336 is the way to go. It's cheaper than the 7424, and it already has the proper counterweight installed. Plus you can get it locally so you don't have to pay S&H.

I am still a bit confused. If I bought the 7424 from CMA do I need to buy a different weight? I did buy the kit so I am using the velcro backing plate instead of the screw in pads.
Thanks, Bill

Yes it is a good idea to get the # 6 weight if you are using a 6 inch backing plate and 6 inch pads like the ones CMA sells. It is supposed to balance the machine better. I spoke to Jack at CMA awhile ago and he said they have no problems with the 5 weight and 6 inch pads but if you get into the higher top speeds of the mavhine you may feel a difference. Coastal says get the 6 weight and Autopians say #6 weight.

Thanks for the info.
Doesn't CMA sell the 7424?
Shouldn't they be selling the other then?

They may have to buy in quantity and have lots of 7224's in stock.
I know that machine cost them at least $136.00 maybe more.I was going to order special order one from Home Depo and seen the cost on it which was 136.00. Lowes must buy a truckful to sell at that price.

BradE · 02-03-02, 06:38

I would get the #6 weight. You might not notice it on the lower speeds, but when you get to around 5 or 6 the machine will vibrate pretty bad if the proper weight is not installed. I think you can get the #6 weight from www.coastaltool.com for around $2. But then you have to pay something like $6 shipping.

So does anyone want to purchase a 7336 from Lowes and ship it to a poor Canadian that is getting gouged by local tool shops?
Paypal anyone?
