Broken tap removal

Anybody got a trick to removing a broken 3/8 tap from a hole? Buddy was cleaning up threads in engine block and somehow snapped the tap off.

Most women like the strong, silent type… Fortunately for me, my wife prefers the out-of-shape, mouthy type.

Re: Broken tap removal

I'll have to bookmark that, it looks fantastic. It would be most difficult to drill a tap for an easy out. But those look like just the right thing. Let us know how it works out.

Re: Broken tap removal

If that set works, you will be money ahead.

Here is the set like that I am used to.

You can also make a chisel out of an old tap with a Cupped shape on the inside.

I can send a Picture if you're interested in that idea.

Carbide is the best thing for get HSS taps out.
But carbide prefers a Ridgid setup or it with chip and break.

Dremel tool with carbide Deburring tool works also especially if it cannot be setup in a milling machine.
