I have a broken exhaust bolt on my rhino and all the bits i have tried to use to drill it out have failed. What do you guys recommend to get the bolt out. Thanks for the help.?

It isn't hardened, you are either using a dull twist drill or you are spinning the drill too fast.

Where are you in SoCal?

Close to Riverside?

Tungsten carbide would be my choice, but I'd use a reverse cut bit no matter what I was trying to remove.... 99% of the time the bolt will come out before you even have to try and get an easy-out in there.

When you say they've failed, are you breaking them or are they just not cutting? Going fast isn't always the best method for something like this.

They arent cutting and a few have broken

You break a carbide drill using a hand drill in that hole and you will be either looking for a laser guy to get the drill out, or you are buying a new head.

Bring it by tonight, or first thing tommorrow and Ill do it while you wait.

Did someone say "laser?"

Not cutting sounds like dull bits...

lh drill bit and drill slow, it'll catch and make the bolt back out

they work well IF you can find em... a quality nitrided 10% cobalt bit (the gold ones in a black and decker set) should take it out...

Put a small pilot in first 3/32 or 1/8, the smaller the bit, the faster the RPM... Step up to a 3/16 if your centered up good...

Damn,

Talk about feeling like a jerk.

I never thought to ask if THE HEAD WAS OFF. Dammit. You'd be real lucky to be able to do it on a Rhino or Teryx while it was installed. Sorry for having you come all the way out.

It was good to met you anyway SM. Good bullshit'n too.

Let me know if you change your mind about the rest of it.

LOL part way through the thread I was thinking UH OH I bet the head is still on, sure enough.

Hope you get it sorted it, not a fun job.

If its broken off down inside a hole you may have to hit it with a small end mill to get a flat surface to drill into. The angle breaks are kind of a bitch. Tough to do on vehicle. Once you get a hole in it (I'd use a cobalt drill) using cutting oil at a relatively slow speed then soak in a 50-50 mix of acetone and atf (best thread release known to man) and use appropriate size easy out.

It CAN be done with the head still on the engine. bulb I work on Rhinos and Teryxs every day and see this pretty regularly. I have only had one stud that I couldn't get out with the head still on the motor. It will take a lot of patience, and you have to be limber.
KMS Performance sells some studs that they guarantee that are unbreakable. I have not tried them personally. Most of the time I see broken studs because of a poorly designed exhaust system. Flanges that are too thin, mufflers that are mounted too rigidly with no coupler in the exhaust to allow movement, etc.

Try a small masonry drill from home depo or where ever. They are carbide tipped and will cut through anything. Don't spin it to fast. Then use an easy out.

One thing on my bucket-list was to agree with John on something. I've found it! I'll also thank you for the tip, Mike!
