Looking for these---I forgot where I bought them from...I know there carbide and are used to cut aluminum. Anyone help?

Thanks

I have a basic question about these inserts.

Are all these triangular inserts you see in different catalogs made to a standard size.

I have only been using one supplier and alway wondered.

Anyone have an idea what size these are? It's a 3/8" holder. The only number anyplace is on the holder: MAR-6

TCGT inserts have the deep chip breaker for alunimum... they are great on wood and plastic.

the 51 at the end signifies a 1/64 radius at the tip

one with a 52 at the end signify a 1/32 tip radius

TCGT21.51..... the 21 means it fits a 3/8 tool

51 is better for facing and wrap channel shoulders.
52 is better for turning imo.

Do you think you get a smoother finish with the 52 because it's larger??

I have just always bought the 51's and never thought about it.

Yes, when you are turning .
51's are too sharp.
Great for facing to avoid the glue lines.

I would like to order some of these as well. I was looking at this chart:

https://www.carbidedepot.com/formulas-insert-d.htm

The 2 is the inscribed circle, what does that mean? Lol.

The 1 is the thickness, which seems pretty self explanatory.

I'm looking to install these on a 1/4" holder for a hightower lathe. Should I just go ahead and find a 3/8" holder to buy along with these? I have a QCTP, so I could drop the center down far enough to use bigger cutters.

It doesn't have to have a 3/8 tool. The picture at the beginning of the thread is the 3/8 cutter insert on a 1/4 inch tool ...I do it all the time it works

Thanks a bunch for that info - IIRC once upon a time I bumped into
inserts for 1/4 holders. I think they were specifically for boring bars...

I'll try a search or two.
