Come See the Drill in Action at The H&K Quarry!

Zzzzt! Zzzzt! This is the drill that drills the holes the chemicals are put in for the blast. It drills about 50 feet into the rock of the quarry. That is how the blast gets started. The drill is attached to a truck, as you can see in the picture.

The drill is also a simple machine as well as a compound machine. It is mainly a screw. If you go to the H&K Quarry in Hilltown you can see the blast of your life.


Here a picture of a drill making holes for the explosives.

When all the holes are drilled and filled with chemicals, the blast will be set off.
