Much, much, more detail.

The answer is likely to be carbide with diamond grit embedded in
the tip.

Hi,
It's so called spline type lug nut on a small Japanese car after
market rim. The nut spline cap broke off(it was hollow tubing kinda
thing, not solid metal) Now the tapered nut is in a recessed hole
making it almost impossible to do anything. Time to put on winter
tire/rim and I am stuck. Out of 5 lugs this one is giving me a big
headache. Having almost no room to do anything, drilling was my idea.
Think the El Cheapo lug was the cause. I was using air impact wrench.
I suspect the cap was partially cracked on the side by road debris or
something. It shouldn't break(shear) off like that. I was even
thinking about using welding torch sacrificing the rim and/or stud.
So far no snow yet, so I still have some time on my side.

I bet you can get it with a screw extractor then.


Advance Auto parts sells an extractor for removing tapered "security" lug
nuts,they come in a couple of different sizes.Saw them on my last visit,in
the special tool section.(or was it Harbor Freight??? senior moment!)
