Why would you use a titanium coated drill bit? Simple; especially if you drill a lot of holes. Drill bits get hot (it's the friction you know!) and the hotter they get the less they achieve because the more blunt they get, more quickly. Titanium stops that happening.....Or at least slows it down a lot. Normally drilling meatl is a slow job, on slow speeds. These drill bits allow ou to increase that speed by up to 4 times with the same, perfect results.
