OK if this is in the wrong place I apologise in advance, but no one will look at it in other sections.

I formed a strip of the stuff into a tuned pipe bracket now when I come to drill it the bits just glow red and hardly mark it.

Hmmmmm.

I would use a center punch on a hard surface underneith then use a small carbide or titanium coated bit.Make sure the bit has something to bite into and make sure the bits are sharp!You want to go very slow and if it gets hot use a bit of 3 in one oild to help cool it.Use a bit of down ward pressure to.Good luck..

stainless

Use a drill press as slowly as you can and with lots of downward pressure and oil.
a new bit will help.. if you drill stainless at a high speed it will work harden the stainless.

I agree with AdamH. Also it will help to drill a small hole first, like a 1/16" and then a 1/8"

I have drilled thousands of holes in stainless steel. If you have only a couple of holes to drill a standard HighSpeed drill bit will do the job, but its gotta be really sharp. High speed and push really hard. But when its almost through you have to back off on the pressure a little bit otherwise the bit more than likely will snap just as its about to punch through the other side. Be careful that you don't do this at eye level, a drill bit shattering can send very tiny bits flying with enough force to pierce skin to over 1/8" of depth at over 3 feet. I would highly recommend that you clamp the piece down in a vice or something, because just as the bits about to punch thru the other side it will suddenly catch and spin the piece if its not properly held down, I can tell you from experience nothing cuts your fingures up as well as stainless steel except a good sharp knife.

drilling stainless steel

I have never drilled stainless steel rods but i tried threading a piece of 8mm stainless rod. Well forget it the threads in my die were gone after 5 minutes of trying to thread the rod.

Twobeers has got it right except!!

Twobeers has got it spot on except for the high speed part, a medium speed is the way to go as it limits the heat build up in the tip of the drill and helps keep temper in the drill steel.

Otherwise take note of Twobeers post as it is too easy to do damage to yourself if the drill grabs and the "job" is not clamped.

Remember the lubrication as well

Oh, most definately a medium speed, even just slightly less. Once a standard bit starts glowing red, you pretty much can write it off as sharp. And cutting oil is really a good idea. I was taught by a 50 year machinist while I was working maintenace in a plant environment.

Thanks for the replies

The first two new HSS drill bits I used were shot before even one hole. Today I tryed to obtain tunsten carbide bit and the only place i could find their £10 - only want to drill four 3mm holes. Bought a cheeper cobalt bit instead and give it ago tomorrow. Thought it would be easy, next time ill use alumumium.

rockcrawler above is the only one who has posted recently on another thread. Everybody else was around a year or more since their last post for anything. If you stand on your head while drilling the stainless steel through a can of dryed milk rolling on a treadmill, it will fly.

This of course only if the Holy Grail is on Crack while the Chinese weights on the tailgrips send a letter to the city ending Lipo flying within said city.

A problem with Fasst systems would solve this tho.

Lego you got to hang around the hot girls thread when you haul your helis to day care to eat some popcorn on your way to the job that you love.

But this is only my opinion. Hope this helps you cause it wont get me any closer to Vetran status on RR when this thread gets moved to the Off Topics.

Hope you can find a local flying club without doing a search first.

Have I covered everything?
