Is this diamond cutting blade installed correctly? yes or no

[JohnfrWhipple]

The grinder is a Dewalt. The directional arrow is shown on the top by the half arrow. The spin is clockwise. The guard has been removed for your viewing pleasure and because I think they get in the way.

So - is the blade on the right way or the wrong way? Please vote.

The "directional arrow" is on the TOOL, not the blade, so how would we know? Look at the label on the blade and see which way ITS arrow is pointing. The "smart way" to install the blade is make sure BOTH arrows are pointing in the same direction, then you don't have to ask us about it.

LOL
It is a trick question.

Judging by the trails coming off the diamond bits, the blade is on the opposite way it was previously used.

I agree with what the others have said. I think it was installed correctly and used, and flipped for the picture to trick us.

That John, he's a tricky guy. Mr tricky man.

I was thinking it was tricky because the blade is not directional.

is the blade harmonically balanced?

FWIW, some blades are directional, some aren't. SOmetimes, you just cannot tell without looking for the marking on the blade, and that is not visible in the picture. If you need to remove it, then reinstall, sometimes you'll tear more diamonds out if it isn't installed the same way...the diamonds are hard, but the method used to hold them in place isn't anywhere near as hard or strong.

HJ. No sticker on the blade. It's gone. The arrow on my tool is easy to spot. Can you not see it?

LLigetfa. It is not a trick question but something most tile men should understand how to check.

RSCB. The blade has not been stepped on and is well balanced.

Vegas. I did no tricks, no photo shop. You guessed wrong. I did have the blade on backwards. I was showing you guys a simple mistake a simple way of checking your blades. Noticed it in the sun when I was having a coffee break.

Reach. The blade is directional, I have never seen one that is not.

You can tell easy which way a blade should be installed. The diamonds create little Comet like groves on all diamond blades. A comet has a tail. A trailing edge. The diamond should cut first and the trail or tail should follow.

I have bought blades that have been miss labelled. I always install my blades like the photo above.
