Bets –
Works as expected
Works as expected. Good price, good delivery. Would recommend.
Richard E. Fischer –
Well designed
Nicely adjustable. The handle is long enough to permit lots of torque, and the rubber coating is a plus
Andy –
Works well enough, not the best ever
I like that you can adjust it to fit different sizes but at the same time it doesn’t stay where you put it very well. It will work for you most times. If you have a really stuck on grinding wheel you might have a hard time using this. I should have just bought the right sized tool for my application, but this is working for me.
Duane Harrell –
Adjustable

GREATNESS PAPA EVER! –
It works
No matter make or size it works, love it.
Matt –
Tooth popped off
Seemed to be pretty sturdy, However, the first time is used it the bolt didn’t stay tight. Then one of the teeth or rivet popped off. It did feel good in my hand though.
Giordano Paredros –
Need it to change saw blades
I recently bought a Makita angle grinder. I needed a pin wrench (not included with the saw) to secure and change blades, so I got this looked good, feels good to my grip, fits the saw and my bag. What more could I ask for
Real Name Attribution –
Broke after first time using
I wish I could share how this product worked, except that it didn’t. The pins are made of cheap material, cheaply fastened and not even flush to the wrench portion, so that as soon as I put tightening pressure on the tool it broke.Don’t waste your money
