Lisle left hand drill

[rhandwor]

Has anyone used one of these? Will they hold up for heater hose fittings. If any part is above the manifold I normally use a 3/4 blunt chisel and make it v shaped and use a screwdriver and thread out. I haven't had any break flush but if I run across one I wondered about this drill. I have a good 1/2 pipe tap.
This company has very high shipping cost but Advanced sells them.

Ok... I have used left handed drills in the removal of broken bolts. Specifically a head bolt or two but mostly other machine equipment. Left handed bits do work great and have gotten me out of more than one 'OH SHYT' moment.

That bit on ebay is a type I have never come across... and does NOT appear to be a lefty... the flutes spin in the "righty" direction... I could be so wrong... as I often am... mostly because I have never seen one like that. It almost looks like an ANNULAR bit and I have used those as well to drill perfect holes in sheet metal and plastic.

It's made to drill out a broken heater hose fitting the big center piece is so you won't damage the threads.It's expensive but worth it if required. I was worried about Lisle quality?

It looks like it cuts left.
But I do not see the purpose of it. I do not think it will cut with out a lot of tolerance.
Normally you put a mandrel where the first cutter is.

Can you explain what you mean by heater hose fitting? I can not see your use for this?

Ahhh ok... now I see it... Lisle has several tools in my collection. I'm happy with them. I am not an engine guy so I have never had that opportunity with a heater neck/fitting.

Most of my torx bits are Lisle and have yet to mar one beyond usefulness. I have broken Chinese craftsman tho...

The fittings leak and when removing occasionally break. If they have enough above the manifold I use a couple of chisels bend v -shaped and remove with a screwdriver. As they are corroded I would use a 1/2 inch pipe tap and clean out the threads.

I got it.
Having several types of easy outs and assorted stuff for thread repair it just seemed odd.
Thought it might be a special type of fitting.
Some times hack sawing down the pipe to slit it lets the easy out dig in.

If trying an easy out I would try driving a triple square impact in and try an impact wrench . I've had easy outs break and they are hard to remove.
