I am hereby proclaiming that I will never find myself in need of such skill, so will dutifully avoid watching the video.

So, what are the odds I’ve just jinxed myself?

Thanks for posting! I never thought of center drilling a bolt to use as a guide. Great info, David

Perfect timing.

I snapped a head bolt on one of my outboards last night..

That is neat, but I don't have a lathe to make a drilled out bolt to center the drill bit. I wonder if anyone sells a set of bolts that are drilled out for drilling a broken bolt. Of course I would need a set for SAE and Metric.

Or better yet, avoid breaking any bolts!

[billybek]

That is a great idea!
Thanks for posting the video.

if you use an axle grinder , you can get it removed pretty easy, especially in aluminium the grinder goes through it like butter, just a single cut along the lenght of the bolt usually does the trick

I wondered the same. Hint: Could make a nice little side biz for somebody here with a good lathe. Sell a set of the more common metric and SAE sizes.

You dont need a lathe for that. A good drill press and a bit of centering will get you there just as well

What is he have so many broken bolts to begin with? lol

McMaster has a few vented bolts that would get you started.

Just hit the broken bolt with a punch to start your bit. Takes seconds and works.
One size fits all.

Whacking the face of a bolt with a hammer, a little heat around it, turn in a hair and then out, impact, always helps.

To bad none of these tools will remove my broken spark plug threaded section.

Spring loaded center punch and left handed drill bits work fine from my experience anyway. Good video though, it's always nice to have options.

Wish it were that easy. Plug snapped at the threaded portion in my 2010 Cayman. These won’t work.
