HSS indexable inserts , link in post

The 0.15" groovers look interesting, though I am puzzled that the LH as RH ones look identical. I can imagine using those to make lock pins and wafers.

It an interesting indication about issues of scale that the HSS ones cost the same as carbide.

Oh, yes, I see the point entirely. I was just observing that the small production levels of a considerably easier to make part leads to price parity. In some ways I am surprised that they are not more exspensive, than carbide. I am wondering if they are actually made the same way using powder metallurgy, which would potentially make them a special run on the same machines, rather than making them by a completely separate process.
