Drilling for rivets

[tmoretta]

I am finding that drilling the hundreds of 1/8 inch holes in the 818 frame to rivet on the aluminum is a killer. Doing the riveting is super easy compared to pushing a drill. Anyone have a recommendation as to the best (sharpest and most effective) drill bit to use?

Buy them by the dozen and keep swapping them out. I used them for about 50-100 holes or until they break. Also buy #30 drills instead. Makes it easier to install the rivets. I sell them on my web site if you cannot find them local.

Thanks Mike. But cobalt or some other type of bit is not better?

to let the drill do the cutting. I have been a machinist for many years and the most common mistake when drilling holes is to apply too MUCH pressure. I have been involved in many builds over the years and this is the thing I recommend the most.

For the 1/8 holes I'm using a dremel tool w/ the 90 deg attachment. This works great for tight places and does a pretty good job of making quick holes. I also put some cutting oil on the tip of the bit before use. Just be careful, I was drilling holes for the trans tunnel last week and the bit caught my glove, which pulled the bit through the glove and through my thumb to the bone. I cut one of the nerves in my thumb, but other then some numbness, all is well. I feel like should just rivet my thumb since I went through the effort to put a hole in it .

For those looking, more precisely here.

For a soft metal like aluminum and even steel square tubing, better bits don't pay off much. Spend your money on bulk packs of cheap bits.

I got these tiny ones on Amazon:

Combined with a short drill...

... I should be able to get almost everywhere without a right angle. However, this little sucker gets me just about anywhere and still has plenty of power:

I've been using Chicago Latrobe short length bits that I bought from Amazon. They come in a package of 12, but I haven't used but a few of each size so far. After each drilling/riveting session I give the used bits a quick run in the Drill Dr. to resharpen them.

There are plenty of other choices, these are just what has worked well for me.

I use the packs of double ended TiN bits from harbor freight. I only used 3-4 to get my build to go kart stage. Lubrication and easy pressure are the key. http://www.harborfreight.com/7-piece...its-66213.html I just bought a multi pack of bits for the 3/16 holes http://www.harborfreight.com/316-in-...ece-61545.html

I place a small cap on the floor when I'm drilling with 1/4 inch of oil in it. I dip the bit in for every hole, it helps keep the drill cool and makes for nice quick clean drilling!

[Frank818]

What type of oil exactly is best?

[Canadian818]

I stole a bit from work, still on my first one, lol. Blip the trigger a bit, keeps the bit cooler.

You can get "cutting oil" from Harbor Freight or almost any store selling cutting tools such as drills and saws.

Nope. Plain old black oxide #30. If you're breaking them it's because the bit is dull and you are trying to wear a hole through the metal by applying pressure rather than letting the bit cut. I can do a whole roadster build with about 5 bits (if I could keep from misplacing them I could probably cut that down to 2 or 3!).

I ordered the pack of #30's from Mike; they work well. I'm almost to go-cart and am only on my 3rd bit (broke one, only tossed one for being dull so far).

[RM1SepEx]

I use whatever oil is handy
Like I said only 3-4 bits to go kart...

X2.

I got my roadster to go cart stage w/2 of them. I found lubricating w/bees wax worked best.

HTH,

I don't think I used more than 3 or 4 bits. I used regular motor oil as a lubricant (also keeps the bit cool). If the oil starts to smoke - add more and reduce the pressure. You also want to use your drill on a slow speed. Using the drill at high speed and using a lot of pressure will kill your bits and make it all go slower.

Cool advise. 2-5 bits to go-kart sounds out of this world kind of low
