Screen 7 - Slinkies

Collect the E-Tank if desired, then drop down.

Slide to the right, and use drill on the slinkies. Switch to buster at the end and proceed.

Stored Charge

You can use the stored charge technique on the slinkies here. Technically the slinkies take two hits from the drill bombs, one from the contact and a second from the explosion. You can switch back to buster after the contact damage on the second slinky to save a small number of lag frames.
