The promotional image has a blue powder coating on the inside of the drill but as you can see in this image this is not the case. trade in goods. I can't say it really makes a difference but not only am I not a fan if the product advertised doesn't match the product received hence -1 star. When it comes to the actual work, I've used this to drill through a wall for an ethernet cable and damn it was efficient. Very pure, very strong, amazing product.
