g It's too bad that term has stuck. I've talked to a lot of people over
the years who don't realize that "solid carbide" actually is a sintered
material, with tungsten carbide and tantalum carbide particles cemented
together with cobalt and/or other metals.

The genesis of the non-solid variety, as far as I know, is that in the
beginning, there
were cutters made with steel shanks and the cutter was welded on, probably
during the sintering process. I know this was true with carbide circuit
board drills. I'm sure nobody makes them this way anymore, at least in
modest sizes up to a couple inches diameter.

Solid carbide = 100% carbide as opposed to just carbide tipped.

I believe the MSC search, which I think sucks, is due to either
manufacturer key words or just that MSC had a bunch of college kids
typing in stuff, (data entry), to get their catalog into web format.
every one typed things in a little differently. Most annoying when
you get stuff like

1.0
1.00
1
1.00
1"

as selections for size.

I still think McMaster-Carr is the gold standard for web sites.
