3 inch air cut off tool HF

Got this at HF. The only 3 inch wheels I found at Lowes just fall apart
at the shaft. The shaft is not loose or wobbly.
It just has a center bolt and washer. What do people use for these??
Do you have to remove the shroud and use 4 inch which are common?
how do you attach them?? any interesting mods..???

What kind of wheels are you trying to use on it? There are metal and stone types. You have to let the tool do the work and not press on it, as that will cause premature failure of the disk. Also if you let us know the model # of the grinder we could look to see what you have. And let us know the type wheels you are using, too. Do they have the diamond knock out in the middle?

no diamond ... not that good.. Its just a cheap tool... I just saw they lowered the price to 7 bucks.. yikes... I rigged up some washers and a new longer bolt.. it will be good for little notch type cuts.. nothing
heavy duty.. HF strikes again..

I think I have the same cut off wheel, I bought mine 10-15 yrs ago. I've never had any problems with it or the wheels. I know I've bought replacement wheels at both HF and sears, not sure if I've bought any from the big box stores.

Just went out to my shop to double check. I have 2 different brands of cut off wheels, 1 HF and the other unknown but both made in Taiwan. Are you sure you have the washer facing the right direction?

theres nothing but a round mount... If I want later I can make a custom mount with washers to keep the wheel centered but also supported..

Mine has a thick washer like piece that is about 1/8" or so thick, it's flat on one side [goes against the wheel] and the other side has a rounded edge. The bolt has a recessed hex head. I didn't bother to take my wheel off but I'm sure either the tool or the washer has a raised section to hold the cut off wheel.
