i wanna buy an indexable carbide endmill for corner rounding. I want a 3/8" radius. Does anybody has try swiftcarb superbee or radstar or do you have another brand to sugest? It's exclusivly to work in aluminium.

R3/8" indexable ???
2 flute -- a bit slow --- a fine finish with 1 or 2 passes may be difficult
would be a lot cheaper HSCo corner rounder ( 4 flute ) and a lot more forgiving on the heavy cutting, and would last a fairly good length of time in Alum. and may be faster than the CBD
first of all, if you look to radstar, the size of the tip is only 1/2" the holder is 210$ and it is avaible in 3/4" or 1.250" shank you only need 1 insert at 42$. Also the same holder fit for radius from 9/32 to 3/8. I make a lot of part that have a linear contour from 38" to 125" rounded. So if i can feed twice faster, that tool will pay itself in short time.
The swiftcarb superbee is a bit different. Tool tip is big enough (.750") but it is just 1/4" bigger than standar HSS corner rounding endmill. Holder costs 187$ and you need to insert at 27$ each.
So the question is not Carbide or HSSco? But how does perform that kind of endmill in alu?
Boy, are you quick off the mark,
didn't have that up long before editting ( didn't leave a comment to say I edited, it was that quick )
yeh, quick look at radstar told me my post was sh*t, and no-one likes mud in the eye, so I changed it
Still those tools won't finish the rad in 1 pass, unless roughly formed in the hogging out stage, even then, it's a lot of arc contact all at once, may work quite good with the 2000, 3000 Alum grades maybe even the 5000, but it would struggle with 6061 and 7075
I would also imagine they would be quite noisey to use
