Sandvik, Kennametal, and about a hundred other outfits publish them.
Mostly so their potential customers can pick wich tools suit their needs.
The internet might work too. You never know.
Hmm, the Kennametal site has interesting insert application guides,
but I fear it assumes that you are a major manufacturer that already
knows the grade and coating that you desire.
Other sites of a more general nature?
PS. To my surprise, Fastenal carries machine tooling...
Trevor J>> Where is a good guide to the varied insert coatings and grades? >>
The paper catalogs are the thing for this sort of lookup. Easy to scan
through the various coatings and the assosciated charts of best
applications and work out what the coating is best applied for.
here is one sheet to keep handy. There are several others if you search
a little for them. The problem is that each carbide mfgr. has come up
with its own grade numbers. C1,C2 C3........... don't get used any
more. They were the standard grades.
I have been wading through the manufacturer's varied types, and C2,
C5, C6... seemed simple. Then I got to the individual pages for the
inserts and lost what was left of my mind.
I will be machining steel / aluminum / cast iron / bronze on a 700W
X3 (max RPM 2,000, IIRC) and / or a 9x26 lathe. I haven't the
horsepower to drive the wild stuff, nor are my machines solid enough to
really drive the tooling hard. Nor do I want to.
Time to surf...
Problems with insert tooling for the HSM:
1. There is absolutely nothing simple about the vast array of base
materials, coatings, sizes, styles, etc. of inserts.
2. Just about all the insert tooling was developed for serious
production use on serious high HP rigid machines and performs poorly on
HSM machines that can't handle the heavy cutting loads and speeds
required for the insert to work to design spec.
So my recommendation is to go with the small amount of insert tooling
sold by places like Little Machine Shop and similar that advertise in
HSM magazine and deal only with the smaller machines. What they sell
should be selected to have some chance of performing ok on said smaller
machines. When you have that 60,000# 30HP machine, then you can
experiment with the ceramic inserts and other exotic stuff.
According to Ignoramus30517 :

I don't think so.
It looks more like a boring bar for use in a lathe. I would not
expect the ground flat to be so far from the end for use in a boring
head in a mill.
I would usually put it in a tool holder with a V-bottomed slot,
and tighten one of the setscrews into the ground flat.
It looks like a nice bit of gear. The only thing which would
make me like it more would be if it had a solid carbide shank, with just
a short piece of mild steel silver-soldered on to accept the insert.
(The solid carbide bars have less problem with chatter with a long
extension of the bar. I've got one very nice tool of that sort, which I
lucked into on eBay some years ago.
The mix of insert materials is nice too. I suspect that some of
the un-coated ones have sharper edges and could produce a nicer finish
with light cuts.
