Thread: angle grinder wrench

The nut on my angle grinder was stuck. I made a BFW. It is amazing how those lock nuts can get super stuck sometimes.

BFW next to factory wrench.

That is a big wrench. I’ve had a few that were suck real bad too. I have never thought to make a better wrench though. I just usually wind up breaking stuff instead.

great idea. Make it perty and sell them. I bet you could make a killing.

That looks great but wouldn't a cheater of 1/2 pipe or so maybe 3/4 work on the factory wrench?

Box end wrenches work great for that also.

I was bending the factory wrench without a cheater bar. It was a round nut with four holes, no place for a wrench. I tried using a hammer and a punch to spin it off, I also tried a big pipe wrench, the pipe wrench would not bite.

My grinder has a little button to press to keep it from turning when i take the disc off. Not sure if I could press it hard enough when using a wrench that big

I nearly sheared that pin off trying to get the nut loose on one. It bent it badly and bunged up the case. Wound up having to get another grinder and lost the wrench for that one. Bought a replacement one that is adjustable and sucks wet dog fur. One like Charlie's would be far preferable.

Ive been in that spot.
Normally the button to hold it still fits in a hole so you just have to line up the hole and button and it wont turn. I think the last one i delt with that had the little holes in a round threaded washer i ended up using pin punches in the holds enough to get a bar between the pins and turn. They should be made with a head for a wrench.
