best way to penetrate through metal?, needa drill a hole through the metal of the celica Options

[daazndood]

hey guys. unfortunetly, my 404 rear lip doesnt line up exactly with my rear bumper. the end of the lip, where you drill the holes to screw onto the car, isnt long enough to reach the predrilled holes in the cars wheel well. so i need to drill new holes a little closer to the side in order to screw on my lip.

i've noticed that this part of the car is made of metal. im having a hard time making a hole through this. any tips for me?

its the part in the wheel well of the rear wheels. on stock celicas, it has this rubber thingy. its opposite of the area where the side skirts screw on.

ummmmmmm maybe a drill??

[playr158]

lol yea use a drill dude....black oxide bit is good stuff

[daazndood]

haha. i forgot to mention that i cant drill through it for some reason. the drill would just keep going and going but not go anywehre.

[playr158]

thats cause u are using the wrong bits and/or drill

get better bits...

and u can't say it won't cause i've drilled every part on a celica

time for some new bits.
drill bits are consumable items, they do not stay sharp forever. once they stop drilling so good, you replace them.

[uberschall]

invest in a center punch too. that way you can precisely mark where you want to drill, and help keep the drill bit from walking on you.

How about a spring?
Crankshaft journal?
axle shaft? I'm sure I can think of more if I try. ha ha

...is the drill in reverse? (when u pull the trigger, does the bit spin counter clockwise or clockwise?)

thats awesome.

[97lestyousay]

Is the bit tight, or is it spinning in the chuck?

[daazndood]

yea, its tight and its going in the right direction. i guess the drill isnt strong and /or sharp enough to go through the metal. its a pretty basic electric drill so im guessing its too weak

[devilsden97]

when u say "basic" do u mean cordless....or one that plugs into the wall (aka corded, i just think that sounds stupid..."a corded drill") if its cordless how many volts?

[daazndood]

its cordless, but i dont remember how many volts it is. its not on me right now, becuase im visiting home till tomarrow. it is lower end though. even drilling through the fiberglass lip wasnt so easy for it.

if i drill metal i ALWAYS use a drill that plugs into the wall. If im forced to use a cordless i try to get a higher voltage one, and use the higher torque setting. (they usually all have a switch for 1)speed 2) torque) then I use light to medium pressure and just let the bit do all the work...some kind of lubricant can also make it easier on the drill, so that its not binding as much. Good luck bro.

edit: also, try a smaller drill bit first, then go up in size untill u get to your desired diameter...less metal removed per bit...little easier on the drill.

yeah my dad told me it would be alot weaker then a corded drill. i guess i gotta go look for a corded drill now. or a stronger cordless?

thanks though everyone!

stronger cordless will do it....i try not to use lower then an 18v cordless on metal.

[97lestyousay]

There is nothing real technical about it, as Manny said originally
the bit is toast. I have a cheap cordless that will buzz right thru
a body panel no problem with a good bit. I usually vari the pressure
until I find what works best.

[6gsillyca]

Dumb question: why is higher voltage better? When I was shopping for a drill I was going to go with a 18v drill that had a speed of 0-400/1300 rpm or something and ~280 ft lbs.

I opted for a 14.4v impact wrench with a drill adapter that puts out 2300 max rpm and 1050 ft lbs.

Even though the impact wrench/drill has less voltage, it has a drill adapter, faster speed speed, and 3x the tq wouldnt it be better? Does a regular drill do anything that I wouldnt be able to do? Wouldnt tq be one of the more important things for a drill to have?

impact drills are the bombdiggity. That'll get the job done. The most important thing about impact wrenches/drills is that they do not overtorque so it doesnt twist the heads of screws off (I used one 5-6 days a week, 8 hours a day at work for 2 summers and it NEVER overtorqued screws, given it was a DeWalt but that doesn't really matter they are all built relatively the same.) Good luck with your project!

[daazndood]

its a 12 volt

Almost any piece of crap drill, will drill though a panel. The sheetmetal
on our cars is super thin. My cordless cost 19.99 at harbor frieght
and it had no problems drilling 6 holes 3/32 dia thu fiberglass and panel,
with the same crappy bit the drill came with. I work at a machine shop
so I could use our shops dewalt and cobalt or even carbide bits, there is
simply no need. A good sharp high speed steel bit and a cordless that
is turning over 500 rpm will do the job just fine. The more rpms the better
untin you get up to 3000 or so then you start burning bits at a rapid rate.
I use 3000 as an example for a small diameter bit, a larger bit burns up
at lower rpms.


75 sfpm(surface feet per minute) is a safe surface speed for mild steel X 4 (pie rounded)= 300
300 / diameter of bit in my case .093" = 3225. 3200 is the highest rpm you should
turn otherwise you will burn up bits all day long, a larger drill would be slower than that.
The formula is the same just divide 300 by the dia bit you are using.
Different materials run different sfpm. This formula is for mild steel, aluminum would
be considerably faster, and stuff like stainless or titainium would be slower.

hmm. i dont know, cuz liek the front and rear bumper arent metal so i can drill through it with ease, but the quarter panel im trying to drill through is tough. the drill just keeps spinning and spinning and not getting anywehre.

ill say it again, maybe you didnt read it last time
BITS ARE CONSUMABLE ITEMS YOU NEED TO REPLACE THEM WHEN THEY GET WORN.
GO BUY A NEW BIT.
the metal panels on our cars are not titanium...lmao, theyre very thin sheet metal.

[purplegt4]

i just imagined him drilling thru the panel with a screwdriver bit.


i hope you get it one day!

[playr158]

hrmmm....


have you tried using astroglyde?
