tuanle,

Please read my post that was posted just before yours. Follow my EXACT description and you will have no problem.
Also, you are not drilling into cement, so ditch the masonry bit and get a bit made for metal!!

greenerob,

thanks. when i posted, i didn't see yours. sorry. newbie. as for the bit, couldn't find it at home depot. that was the only one that was long enough. i'll try a different home depot. not much selection at local one. were you able to drill with cordless drill or did you have to get a corded drill? electric ones have more power right? also, instead of crios recommendation of drilling towards midline, you punch your hole away from midline, right? will try again.

I drilled with a cordless drill. It probably took a little longer though. As far as the angle of the I held the screw drivfer as far towards the center as the tips would allow and then waked it a couple times. I used a long and thick flat headed screw driver.
