I have looked at these online several times since their introduction to the market. I have not yet had a chance to go and physically hold one though. I will get around to it sometime, but I thought I’d pose the question here to hopefully shed a little more light on these 2-sanders.

From looking at the information available online, it appears that they both have the same motor, and the price is the same. Obviously the 6” is a bit larger than the 5”, and so it weighs a couple of ounces more. Are there any other differences between these two sanders that might make one more appealing than the other?

I understand the 2-sizes may work a little better for certain things. For instance, the 5”, being smaller, will fit into tighter spaces. And the 6”, being larger, might cover a larger area, such as a table top a bit better. Motor power and speeds are the same, so I’d imagine the 6” might effectively remove about 20% more material in the same amount of time, compared to the 5” model, but maybe not? Am I thinking about this correctly?

I am strictly interested in the differences between these 2-sanders only, no others. Not interested in air sanders, and don’t need to compare this to the Festool ROS line. I think I’ve already narrowed it down to the Mirka CEROS, just not sure which size? I’m not necessarily going to run right out and buy one, as they are rather pricey, but they are certainly in an entirely different league than other ROS (other than maybe the Festool).

Thanks for any further information you might be able to provide me with regarding the difference between these 2-sanders.

I share your curiosity, Jonathan. The Ceros was pitched to me by a hardware wholesaler and I have not had my hands on one.

To answer your first question, 5 or 6, I’d say buy the size that is the same as what you already have so you’re not stocking and keeping track of two different diameters of paper. The difference in efficiency balanced with cost is probably not measurable.

I watched the video here and I couldn’t see anything that amazed me as revolutionary in an orbital sander (pun intended). I’d think there would be three possible advertising claims for a “new and improved” ROS: Better dust collection, more efficient sanding, and longer life. Am I missing anything, and have you seen any of these claims?

In the final 30 seconds of the video, the procedure to follow to change paper seems a bit tedious compared to what I go through on my PC 332.

I don’t understand variable speeds; I need some education on that (noting your signature line!). How would one know what speed for what material? I would suppose a lower speed on a resinous wood might not melt so much goop into the grit, but I’m not certain of that.

I do like that they have a universal mounting for the pads. Often on these boutique tools it seems there is proprietary this and proprietary that to keep you in the product circle.

I have three aging 332s (5 years) and none has failed, except one switch. It appears they are discontinued, so I picked up two spares on the ‘bay, about $45 each, both in fine shape. These have no DC—I do most of my sanding on a downdraft table. So total expenditure on these tools would be in the $500 range.

I think I just dimmed my curiosity about the Ceros! Thanks Jonathan!

Kindly,

Lee
