titanium coated is just a gimmick, if you know what you are doing you cant tell the difference between a ti coated bit and a regular old black drill bit.


Titanium Nitrated bits do not make much difference on a poor quality bit. It just makes a poor quality bit last a little longer. Our world has been swamped with poor quality stuff. Thats the biggest problem . Most start with low quality drill bits to save money and use a thin coat to save as well. Its expensvie to coat bits. The purpose is to make the drill bits last longer NOT drill better thats all. If you buy a quality coated bit they last a lot longer.everyone seems to go cheap and thats what starts all the rumors.The black oxide is just to keep chips moving in the flutes more freely otherwise they are the same bit if its a quality one assuming comparing apples with apples ie) same flute
