Sounds like you need a decent metal cutting bit and some cutting oil.Excessive pressure breaking the bits.
thought it was the drill ...maybe its the lack of no oil.. i was doing light pressure and going little at a time ..also going back and forth
ill look to grab some from home depot ..well my first hs skink will have holes all over it hopefully i get the hang of it ..if not ordering that tape lol
I use oils on stainless and carbon steels. For aluminum (and soft metals) I use a cutting wax, which melts as the bit/blade heats.
was brand new i got the first batch from local hardware place the brand was irwin ..might be a cheap one..that or the drill is crap..to weak

Is what your trying drill anodized? Aluminum is one of the easiest materials to drill/machine. Do you have the drill spinning in the right direction?
lol yes I'm in construction..trust me I'm not getting it either I'm going nuts..im goon get oil tomorrow and make sure drill is charged 100 percent before i start again
thanks

forgot to mention, don't over heat the bit tip and dip the bit in the wax or oil often to keep it cool.

Nah man, you want high speed with aluminum. Going slow is what brakes the bit. Im guessing the material is anodized, which hardens the surface. But it shouldn't be a problem once you get through the anodizing.

Redi, I stand corrected, your are right.

so that might be the problem I've been going slow

too much downward pressure causes the AL to heat & melt slightly & AL is Reallly Sticky at this temp
high speed + light pressure + oil olive /vegetable oil will do in a pinch I use olive oil with drill press smells better than cutting oil seems to do the trick as well
but if you rocked that bit back & forth trying to get the bit to cut faster (that only works in soft wood) it's way Dull
that bit is now toast
I had the same issue trying yesterday to drill some A/C64's on my drill press
once I eased back the downward pressure & then cleaned the bit with oil
easy peasy
I've had thick AL gum up my carbide chop saw by cutting too fast
again slowed down & a squirt of wd40 , easy peasy

If your using a 9v drill it probably won't ever spin fast enough no matter how u charge it.
Surely you don't use this drill for your construction work?
Maybe a family member or friend has a drill press u could use?
