Carbide insert grade Question?
- Thread starter furpo
- Start date
Furpo,
Cant answer your question directly, BUT..... There is a thread here that discusses selection and purposes of various insert configurations. I posted it from a tech manual from Sandvik or one of the other manufacturers. Just can't remember exactly what it contained. If you have a problem finding the thread PM me and I will do a little hunting to see if I can find it for you. There are just about as many different inserts as there is sand on the beach, so one or more should be suitable for whatever you want to do. The issue is just finding "THE" magic one. Good luck and gimme a holler if ya can't find it.

I've never heard of that carbide designation and tend to think it's a manufacturer-specific number. Those are big inserts (432) probably for a 5/8 or 3/4 (or larger) sized insert holder... It has a half inch inscribed circle (4 * 1/8), 3/16 thick and 2mm radius corner.

You may find the info here on this link. I found TNMA 434. You will have to do some searching though.

Carbide depot has a pretty good tech section. Might find a recommendation there.

Ray, 432's aren't big! Unless you're working on a watch or something. I use more cnmg 432's and dnmg 432's than anything. Great general purpose size. Grade and coating is another story though.
Sandvik has this pdf which is pretty handy. I didn't try to look those grade designations up, but them seem familiar. Haven't had enough coffee yet.

Those grades are manufacturer specific, for the most part, so you need to know who made them to get the most information about them and their application.

NT-55 is a old Newcomer grade equivalent to C-5 and TiN "gold" coated.
545 is a old Carboloy grade again equivalent to C-5 and some kind of oxide coating according to my old Newcomer chart.
Both excellent for general purpose cutting of mild to medium alloy steels (1018-4145) .

Well, I have an antique Pocket Ben, but that doesn't count. 432 is probably my most used size. Can handle all 10 hp on my best lathe. Available in a bewildering array of grades and coatings, and radii. I use an 80° diamond for roughing, some finishing, and a 35° diamond for finishing. That one does profiles very nice, and can get into corners easily. I generally get only small radius in the 35° since it's primarily used in finishing.
That's what I needed! Thanks 4gsr:
I’ve been reading charts for 3-4 days trying to verify what I was looking at.
I went ahead and ordered of FleeBay: 3 TNMG 432 INDEXABLE CARBIDE INSERT 1" LATHE TOOL HOLDERS VALENITE TP-TFR-16, TP-TFL-16, TP-TJR-16
And NEWCOMER USA TNMA 432 grade NT55
Thanks
