Quick Answer: It's really hard crushing ice with an immersion blender, but there are tools and accessories that make it possible. Some hand/stick blenders come with extra jars that you can place the shaft into. Then, you can essentially use your immersion blender like a counter-top blender and make smoothies and crushed ice.

PS: If you don't have the accessory that we mention here, you'll want to get a countertop blender for this purpose. Check out these Vitamix Alternatives or smoothie blenders for your ice crushing needs.
How To Crush Ice With An Immersion Blender
Grab Your Blender and Beaker Jar
First, grab your blender and your beaker jar. If you don't have one, check out our best immersion blender guide, where we show you several options that are capable of handling ice.
There's also a video at the end which features the Braun Multiquick hand blender in action.
Load Up Your Ice Into the Beaker
Next step is to load the ice up into the jar where you're going to be crushing it. This step is pretty simple and straightforward.
Attach and Blend
Finally, you'll need to remove part of the shaft so that you can properly attach the hand blender to the jar. Some immersion blenders go directly into the jar, so you may not always have to do this.
After you've got everything attached, there's only one thing left to do: blend.
Crush the ice to your heart's desire and use it for your favorite drinks.
