Ryobi P553 18V Cordless 7-1/4″ Miter Saw Gets Updated

The Ryobi 18V Cordless 7-1/4″ Miter Saw Gets Updated with a new model number P553 for the USA variant and is known as the 18V 184mm Mitre Saw with model number R18MS184-0 for those of you outside of the USA.

Older P552 model

I originally wrote about this cordless 18V Ryobi miter saw back in late April 2019 when the only available info was incorrect info from the Home Depot. According to their info, the new model P553 was identical to the previous P552 model in all respects except for the addition of an LED light system, that’s it or so we thought. The Home Depot placed pictures of the old P552 miter saw and to make matters worse, the comments section on their retail page mentioned it didn’t have the LED light feature that the “new” model claimed. People even placed comments here on this page letting us know the “new” miter saw lacked that feature.

However now late into the year, Glenn wrote in about a new Ryobi 18V 184mm (7-1/4″) miter saw model # R18MS184-0 that he spotted in the Ryobi Australia page and it’s a completely new 18V Ryobi 7-1/4″ miter saw. I cross referenced it with the Ryobi USA page and it’s the same model as the P553 and now the listing has the same image as the Australian variant which correctly shows a new cordless miter saw, not the same old P552 model.

Actual P553 model / R18MS184-0

The new P553 correct image clearly shows updated styling and some noteworthy improvements over the P552 model. For starters it now has the miter knob in the front which is the traditional placement for a miter saw. The base has been greatly beefed up now with taller fences. The saw arm also appears to be beefed up and the now added a dust shroud in the front of the arm just behind the blade which should help collecting sawdust. Also the dust bag port also doubles as a vacuum port for 1-1/4″ vac hoses. I’m not sure if the old P552 had the ability to hook up to a vac but the new P553 makes it clear that you can use one. Unfortunately the new P553 model doesn’t have an LED cut line system as it’s not listed on the Ryobi listing page and neither on the official manual. That’s too bad though as that would have been a killer feature to have. Trust me, it’s a feature you want on your next miter saw if you don’t already have one with it. The weight also goes up to 19 lbs which is 4 more lbs over the 15 lbs of the P552. According to the P553 listing info, the P553 gets “extended” miter range now at 0-47 degrees left/right but they never really made it clear what the P552 miter range was.

All other features appear to stay the same with a 7-1/4″ blade, single bevel 0-45 degree, cut capacity for a 2×4 and 4-1/4″ cross cuts and compact cordless 18V design.

Back when I originally wrote about the P553, the price for the Ryobi P553 18V Cordless 7-1/4″ Miter Saw was $119 but now the price is up to $149 at the time of writing.

A big thanks to DrewBHAM for originally spotting the P553 and Glenn for spotting the Australian variant!

Just picked up a P553 at Home Depot and not only does it not have the LED Exact Line system, it doesn’t have any kind of laser or LED alignment guide!


That is very strange, it says Exact line adjustable LED alignment system in the Home Depot description. Did the saw include 2 AAA batteries in the box? Also is there a small white door with a screw to hold the door closed under where the 18 volt battery goes in the saw?

No laser or LED of any sort. No battery door under One+ battery connection. No mention of alignment laser or LED in user manual. I’m a bot upset, as I used this article to decide on P553 over P552 – store had both.

Would love your thoughts, please comment.x
