Can you drill through the composite bed?

I'm planning on building a bicycle rack using angle iron and want to bolt it to the inside of the bed of my 07 taco. Do you need a special drill bit to drill through the composite bed? Maybe like a concrete bit or something. I haven't tried yet and haven't found any posts about it. Just thought I'd ask before I start burning up drill bits.

 

Super easy to drill. I used bits meant for metal and they cut right in like butter.

 

What they said ^^^

a side note, wear glasses, some thing to cover your nose and mouth, and long sleves and gloves are great if it's not too hot out. the dust it puts off is very itchy

 

Make sure there is nothing behind where you are drilling. Keep in mind how long your drill bit is too.

 

Thanks guys. It's always smart to research before you start cutting or drilling on things. I appreciate the feed back.
