Ryobi PCL445 ONE+ 18V 4.5" Angle Grinder 

Just went back and double checked. You are correct, in the video I installed the top spindle upside down, however just checked my tool and it's set properly, I must of noticed it at one point. To install the spindle flange correctly: The bottom flange has two flat cut outs which seats it on the spindle nut. And the top spindle nut has a protruding edge that goes into the disc. I'll pin this comment for others to see.

@@thehousemannwhen putting a cutting (thinner) disc on, the flange holds it on more securely with the flat side down. Won’t get to try my actual cut til tomorrow morning, though..

Thanks for stopping by!

Not a bad price

Thanks!

Thanks for watching! It is an 11 thread count: Spindle Thread : 5/8 x 11 UNC Straight from the manual

I have not since I use a smaller Dewalt cut off tool

Oh boy, Yea i can imagine. I'd recommend a 4ah battery

Depende cuanto lo vas a usar. Una de 4ah sería un buen balance.

The lock button is solely a safety lock out. It is not a trigger lock.

Thanks. That’s a bummer because I use an angle grinder to cope trim. You need to hold close to to motor for stability.

@@grputtputt Yea sorry for the late response, ended up catching covid. But I can see how they wouldn't want to lock it on as a safety hazard.

@@grputtputt but nothing a ziptie or small ratcheting rope can't fix 🤷🏻‍♂️😂 #dothatatyourownrisk

I have three electric ones and they all lock on. Anyway thanks so much for responding.

This one should be a standard non Brushless.
