Its wild to think those were dropped there by glaciers.

Would have been good if you gave it more than 15 seconds
Would of been great to see how well it works on a angle rather than straight down

In the states you can buy this - Betonamit - Non-explosive cracking agent. Drill holes in the rock and pour in the chemical liquid and it will eventually break apart.

I think you should do the edge of the boulder not the center.

[vickstaple]

Its made for smaller concrete work, like sidewalks and flooring

[zoltanberkes]

You don't have to push the demolition hammer down. Just let it do the job by its own weight.

[dougmanor]

Seems it would stop hammering every now and then, check your oil level.

Next time use your pointed tip in this case…

[MelPuzon]

Wrong bit. Don't stand on the rock when you do it.
