Carbide Inserts/ Enco

for the shapes any of these should work.

SC*N or SC*R where * is literally any letter since its the tolerance. I would recommend C, G, H, or K as they are tighter tolerances.

Numbers wise you want 42* in ANSI nomenclature, & 1203** in ISO nomenclature. * is the tip radius and bigger is better. in ANSI, 2 & 3 where common, in ISO it would be 08 & 12.

For the chip-breaker & grade/coating you will need to look it up once you find the right size and shape insert, because their is no standard, and each manufacturer has it's own naming scheme.
 
Thanks Dan for the info , guess I'll keep useing these till they melt, there kinda proud of new face mills
This one worked so good when sharp
Thanks again
 
You can always call Carbide Depot and see what they recommend, but they may be a bit more expensive but probably worth it to see what they recommend. Probably worth experimenting with some of the inserts from eBay, they are cheap in this old style. There are probably lots of other styles that would work. I just poked around at few possibilities. Note 432 is a bit thicker 3/16" 422 would be 1/8" thick, your type of holder probably has a range of thickness that it can accommodate.

I would look at a square 1/2" such as 432, 422 or 431, 421 style, SPG or SPC, SPK for aluminum (positive rake, uncoated, sharp edge, something like C2 ) probably also work well with steel in a coated insert. Sandvick H13a is uncoated carbide for non-ferrous and cast iron.

Steel and general machining would look at SNG or SPC 432, 422 style (lower cutting angle, coated, all purpose) KC850 is well suited to all purpose use, roughing, low speed. SNG seems more commonly used for insert holders with a negative rake. Not sure if a SNG will work in your setting, probably need a relief angle behind the cutting edge.
All purpose suitable for wide range of metals:

Possible alternatives if you can use SNG

Diane,

That face mill is an older one. They only had SPG or SPU style inserts back then. You should be good using a SPG422 or SPU422 or 421 if you want a sharper nose radius. It'll work fine for aluminum cutting. Don't worry about using wiper inserts, you don't need them in the home shop environment.
If the face mill was newer, some of the other things everyone posted would apply.

The angle I got up above is 70* that would be a c, SC ? Big difference 7*-70*
Tolerance? I guess G ,, SCG. .? At this point dose it matter
It needs to be 1/8" Thick 422. .? 1/8" only
So a SCG422 is what I need I think :headache:
 
I have some 1/2" x 1/8" square with no holes SPG 422. Got them in a box of stuff. I can send you what you need for your tool and see if they work

Auto thanks for the offer, not sure the corners would work as that is where the business happens
And the cutting angle looks different. All ready have a bunch I bought that don't work
Thanks
 
I just found some that look like yours. re-read my post. forget about the picture I had up.
 
That would be great if they work ied sure give them a try.
Sending pm
 
Better pic of insert mount in head

Don't believe anything but 1/8 " thick will work
I'm thinking the angle has to be the same also
Thanks for all the help
Only half boggled now
