Is there a 4-1/2" grinder that you can reverse rotation of wheel?

[TTMotorsports]

Ok so many many times I'm cutting things on trucks with a 4-1/2" angle grinder and cutting from wrong direction so it wants to kick or blowing sparks directly at you. I'd assume it would need a left hand threaded but to keep that tight but it would be handy on some jobs to have.

So is there any 4-1/2" angle grinders that rotate the opposite direction from standard?

Flip the grinder 180° in your hand and it rotates the opposite direction.

Spinrite Reversible Angle Grinder

The reversing switch lets you choose the disk rotation direction, giving the user better control and reducing risk. The proprietary Arbor system allows for rotation in both directions without any risk of the disk loosening. The hex key for changing the disk stores conveniently in the handle. -...

No clue if the brand is any good or not, but looks like it uses some kind of locking hub instead of just a threaded nut so you don't have to worry about it spinning off. You'd obviously be limited to non-threaded discs and couldn't use flap disks or any other directional disk.

I wonder if you could mod a cheap grinder to spin the other way.

I do that when possible but sometimes the body of the grinder hits the body or something preventing that from being possible.

Assuming they are induction motors, swap start polarity.

And then pin the arbor so it can't spin off.

My buddy has one that you can clock the head every 90*. It was when ryobi was still blue tools but not sure. I’ve never seen them anywhere.

Cause thats the problem. You load that wheel ots coming right off.

Snapon low pro does it but it sucks as a grinder.

Most grinders are a square bolt pattern and i have seen a few that peole have flopped over.

I know most grinders can be clocked by unbolting and rotating and rebolting. His had a button that you push and it would rotate when you wanted

And then tack weld the arbor so it can't spin off.

Fixed.

You can use your normal grinder to change wheels.

The big red HF grinder does that.

Never used it. Not even to see how it worked.

I prefer the sparks to shoot at me. The grinder launches the opposite direction of the sparks.

That's why you pin it...

"And then tack weld the arbor so it can't spin off."

Or you can just pin it and make it easy on yourself..... oh, wait this is Irate and you are who you are.....

Not shit, thats why i agreed with you.

This. Way easier to hold one in tension than one that's pushing at you. But OP's still got tight space fitment issues that probably won't address.

I've got a sawzall that does that. Swivels on the ring gear, the blade rotates, and the handle rotates. Heavy, but versatile.

 

[Muckin_Slusher]

Rotating the head around the motor isn't making the wheel spin the other way.

What are you guys smoking?

Point of view. Its not spinning the other way on the axle, but it's throwing sparks the other way if you flip the axle to the other side.

But that won't solve the problem of the head not fitting in places with the blade on that side of it.

they're usually series wound brushed motors, they're easy to reverse too, google up a diagram

 

[Weasel]

Have DeWalt batteries? They have a battery cutoff tool that goes both ways. Pretty decent little unit from what I've seen.

 

[TTMotorsports]

No Dewalt batteries since I'm a Milwaukee guy but I'm sure there's adapters for that.
