Can't drill into exhaust pipe - SV650.org

21-02-07, 04:56 PM

Ok, my attempts at drilling a hole into my pipe has failed. I have a week to fit my exhaust before it goes in for it's service.

How can I drill a 3/16" hole?

Do I just need a more powerful drill?

Have you got the right sort of drill bit for the material you are trying to drill into ?

Why are you drilling a hole in your exhaust to fit it anyway ?

It's a cordless drill and the drill bit just spins across the surface of the pipe. What drill bit should i be using? I might leave it to be done at the service.

I'm drilling a hole cos according to my instructions I need a hole in the pipe for a securing rivet to go in which is then clamped over with the exhaust clamp.

a metal drill bit
stone has a bit welded into the end
piccy to follow

put a piece of maskin tape over where you want to drill to stop it slipping

For a start some basics, you're drilling a curved surface aren't you? either centre punch or use some gaffer tape(make a cross) to make a start point, lubricate,start slow, use a colbalt drill bit.

If you still have no joy you don't have the right tools for the job.

If its spinning across the surface, it sounds like you've got the wrong drill bit.

You want a bit designed for Metal, preferably a HSS "Hardened Speed Steel" Drill bit. ( I think ) Also if your bit is blunt thats not going to help either.

Thanks everyone

It looks like I have a (slightly blunt) metal bit, will try again tomorrow with some gaffer tape (maybe go out & get a new bit) and let you know how I get on.

You need a HSS "high speed steel" drill bit, its capable of running red hot without getting blunt, whereas a normal carbon steel bit will soften easily from the friction generated. If its a stainess steel pipe it will be harder to drill anyway because the steel "work hardens" as you are cutting it. Try a centre punch and a new HSS bit with a blob of oil on the centre punched start point to act as lubricant.
