What do TAR, TAL, TBR, TBL, TE mean?
These are designations for the turning tool holders (the black bars), not the inserts.
T indicates that it holds triangular inserts.
L & R indicate left and right hand tools. Right hand tools cut from right to left.
A indicates the insert has a zero degree side angle
B indicates the insert has a 15 degree side angle
E indicates the insert has a 30 degree side angle. In other words, the point is centered.
Now that you know that, so what? Use the tool that does the job at hand.
