Carbide insert question

[Mike8623]

Ok folks i just cannot get the ansi and iso descriptions when it comes to inserts.

I'm looking for a insert along the lines of a TPGH215 but about .450 or a little less in length. Can anyone help, and just what is the length of the tpgh215?

 

[ddickey]

~.433"

 

[Mike8623]

Yah, that would work, or is that the size of the 215?

 

[Mike8623]

I'm making a 60 degree v chamfer mill cutter.

 

[ddickey]

That's the size of the 215

 

[Mike8623]

So you are saying it is .215" in length

 

[ddickey]

No it's ~.433" long for a 215 that has .250" inscribed circle.

 

[ddickey]

I may have made a mistake. Redoing my trig now.

 

[ddickey]

Okay, the size of a 215 insert is .250" inscribed circle. A triangle needs three sides being .433" long to contain a .25" circle.
Spilt in two so we have a hypotenuse of .433" and an opposite side of .2165". So that makes the adjacent side or the length of a 215 insert ~.375." long.
Somebody feel free to peer check me.
