Proper Name of this Drill Point?

[extropic]

I got this in a lot of industrial surplus. it's .250 diameter carbide. I believe it's for forcing a hole into hardened material.
I think the principal is that friction heats the immediate area sufficiently to allow the edges of the pyramid, four faceted 'cutter' to displace material creating a hole in the workpiece. If you think I'm off base, please comment.

I'm familiar with 'Hi-Roc' drills that have two straight flutes but I wonder if there is a proper name for this point grind?

My Google-Fu isn't strong enough to answer the question, so far.

EDIT: D'oh! I forgot to add the picture.

Spade tip?


Cutting oil is my blood.

I would call that a Roc-Drill or Hi-Roc type. Different than the one I'm wondering about.

I've added the picture now. Please take a look.

It looks like a spotting drill bit for starting holes in hard materials. Works nicer than a center drill bit for starting holes.

I'd call it a nail.

That was my first reaction as well.. it does look like the tip of a nail…

Then I thought that maybe is for hard ceramic… but those bits look different
