Little Reptilian for gears like in the video regular NLGI 2 Grease or high temp wheel bearing grease will work fine but for enclosed planetary gear boxes found in cordless drills then you would go for a thinner grease like CV joint grease which is nlgi 1 or nlgi 0. Nlgi is just the rating for thickness of the grease, the lower the number the thinner the grease. The most common is nlgi 2 which is what’s used in the video, you can find it at a petrol station or pretty much anywhere
