Deus Ex: Mankind Divided

The Ice Drill in Mission 13 can be found at the beginning, when you first enter the facility. Once you're inside, turn right and go through, where you find the terminal for the ice drill.

Position the Ice Drill at the very end of the big hall and press the button to complete the "Core Driller" Achievement.

This achievement is available to unlock in Mission 13. After you regain consciousness, Remote Hack the expandable ladder to the left and climb up. Go through the door that's on top of there and eventually you'll find yourself into a corridor that has some metal boxes to the left hand side. There should be two guards to the right, right outside a door that's also on the right hand side, but they should be visible in you radar.
Climb on top of that shelve where the boxes are and go through the vent. It will lead you to a big area and two guards will be talking right outside the vent's exit. Wait for a little bit until they split and deal with the one that stays on that level. The other one goes down the stairs and doesn't come back, so he's not an issue.
Go through the door that's beside that guard and go through the other door too straight ahead after evading the security camera. As you enter the room, you'll see a laptop in the stand in the middle and on your left hand side, a console. It faces the rest of the big area you're in.
This controls the ice drill. You are to move it away from the ice that's on the right hand side and towards the far end of this big open room. Once you move it only once (aka away from the ice first), a guard will get suspicious. Use the answer that has to do with security precautions and they'll buy it. Afterwards move it towards the other end of the room and then move it back towards the ice. The button that was previously locked will now be available to press. Press it, allowing the drill to extract a huge cylinder of ice from the wall and the achievement will unlock. EDIT: If it didn't, make a separate normal save and follow the rest of my guide, there have been reports that you need to actually go through the new path you've created with the drill.

Important: The description of the achievement reads "Use the Ice Drill to bypass a large section of the GARM facility.", with the keyword being "bypass". Right after getting the achievement, move the drill away from the ice and leave it there. Look towards the side of the room across the door and you'll see another deployable ladder. Remote hack the lazer grid on top of it and the ladder itself and climb up. Once you're on top, climb on the yellow industrial crane rails and carefully walk on it until you reach the hole that the drill had drilled before. Jump down in it and go through it. Congratulations you just bypassed some of the guards and security measures.

Quick video guide:


Once you start moving the crane a guard will contact you asking what you're doing. You will need to choose 'scold' to remain undetected.
To move it into the right position you will need to use rear, left, left and forward combination (as shown in video).
