150 MM circular saw blade to inches

Hey all. First post here.

I bought a Ryobi RWSL1801 when I was stationed in Germany a few years back and it came with a 150 mm blade.

Now I am in Ohio and need to replace the blade but can only find 5 1/2

150 mm is just over 5 7/8 inches.

I've noticed the standard blade sizes here in the USA are 5 1/2 and 7 1/4.

Will it be okay to use 5 3/4 blade in my Euro spec saw?

I won't speak to your situation, but I have used different sized blades in my saw. I have used 6-1/2 inch saw blades in a 7-1/4 inch saw.


Make sure the arbor hole fits your saw and the speed limitations of the blade is consistent with the speed your saw can generate.


I hope it is obvious that a slightly smaller blade is probably fine while a slightly larger blade could pose some safety issues with interference issues between blade, guard and shoe.

The blade that you have is about 3/8" larger than a standard circular saw blade. Therefore, it is safe to use a 5 1/2 (standard circular saw) blade and you will notice little if any operational difference.

Maybe you can use a 6" blade?

Amazon has 6" diameter blades. What also matters is the bore diameter. I doubt if an increase of 1/8" in the diameter, 1/16" on the radius will pose any safety issues.

It needs to have a 10mm bore for the blade.

Measure Twice Cut Once -- It's a lot easier to cut more off then it is to cut MORON.

Useful for just about anything, www.onlineconversion.com.
For some reason, now I have to open it in New Private Window. Didn't have to do that before.

Any blade that will fit on the saw will work, you may have to find a spacer for the bore if the arbor is smaller.

The bore is 10 mm, per European machines

Good call, Leo.

Use a spacer/adapter or settle for a slightly small diameter blade. I wouldn't trust an adapter that small to be accurate.... just me.
