Ultimate Performance: Ryobi Cordless Brushless Sander P450 - Unmatched Sanding Power! Review

I bought this unit because Dewalt doesn't make belt sanders. This was my first experience with Ryobi tools. I also bought an 18 AirStrike nail gun which I like although it is a bit heavy. The grinder is so weak that I no longer use it. I also sorted the batteries as if there was an endless supply. I only have 4 of these and he ate them all in one sitting. I would not recommend this remedy. It now takes pride of place in my trash can.

This belt sander is ergonomic and easy to use. It has a somewhat slow rotation speed, but large projects will mostly require constant changing of the battery. That thing eats batteries. I have 3 new Ryobi 4Ah batteries and they work great with my other Ryobi tools but this grinder is designed to create friction. Friction = resistance leading to poor battery performance. That is the nature of the animal.

As you would expect, this belt sander works well with a 4Ah battery. Using a 4Ah battery I was able to get a decent 8-10 cu ft grind on a single charge. If you don't need mobility or need to grind a lot, you should look for a plug-in grinder for a lot less money. This sander met my needs for mobility and small sanding areas and managed to capture most of the dust. I haven't had any mechanical or technical problems with it.
