I am not sure where you are drilling; if near the Turbo the Turbo can be removed.

If you Grease the Drill Bilt you need High Temp Grease and you need a variable speed Drill Motor to turn the Bit slow. Even then some of the Grease may Melt.

However, Gease works well on the Tap if you fill the Flutes/Grooves with grease.
