If you have a center drill use that to start the hole.
Try using some cutting oil and a slower speed on the bit and as much pressure as you can put on it. Once the cut starts you shouldn't have any problem going through it. Like winston1 said, a smaller bit to start will make it easier.
High speed and heat will dull a drill bit very quickly.

X-2 although not all titanium bits are created equal, the cheap china made ones that you find comes in a nice little case are hardly good for lightweight sheet metal,if these are the ones you have? stop waisting your time and go to your local NAPA and buy a couple good steel bits, it would still be best to use a cutting oil :thumbsup: I have 25 year old Bits , when they start to get a little dull I'll put them in my power bit sharpener that'll get back in shape,
as far as I know the titanium bits cannot be re-sharpened,

I agree on the cheapo Ti coated bits...pretty junky. That said, I have resharpened them. It doesn't seem to make them any better or any worse. I have an old school sharpener that I got in a tool lot off ebay and is identical to this one. Sharpener Attachment - Drill Bit Sharpeners - Machining Supplies - Machining : Grainger Industrial Supply It works amazing well and will put a factory edge/point on even the hardest bits. In fact, I broke it out and used it to sharpen some of my best quality bits earlier this week.
