This method works, but there are a couple of considerations. First, I’m not as confident in tightening the wheel by hand, so I always use a spanner wrench to make sure it’s tight enough.

Second, thin abrasive cutting wheels are more prone to breaking or weakening with this method, so we don’t recommend you try it with those. You could inadvertently create a situation where your cutting wheel fails with dangerous consequences.

Many Pros do another take on this by running the wheel against concrete to loosen it rather than by hand. Either way works and carries the same warnings. I personally find loosening by hand easier.

My favorite way to replace an angle grinder wheel involves switching out the stock flange with a Hilti Kwik-Lock flange. We originally used on Hilti’s 36V grinder and find it an excellent upgrade for any model that has the same 5/8-inch arbor.

The genius of it is a design that allows you to hand thread and tighten/loosen with just your bare hand. It’s perfectly secure and super-simple.

In the event your grinder wheel helps tighten it down too much, two holes let you get a spanner wrench in to work it back off.

Here’s the easiest way to change an angle grinder wheel:

The downside is that these flanges cost a little more than $50 each. That might be too steep for a DIYer. Having a couple of these on hand for Pros that use grinders often can make life easier, though.

Just buy an X-Lock grinder (invented by Bosch and also implemented by Makita and others). Release: pull the lever and you’re done. Time: 0,5s Attach: push the disc until the mechanism clicks. Time: 1 s. No checking the tightness. If you hear the mechanism click, it’s 100% secure. No unwanted and dangerous loosening either. Like SDS for drills and jigsaws, this makes the old method of fastening discs completely outdated and obsolete.
